Skin Care, Herbal Skin Care Remedies, Home Skin Health, Skin Disorders   (Site not responding. Last check: 2007-10-31) Fatty acids are important to the health of the skin as a nutrient, and unsaturated fatty acids are particularly known to possess fungicidal and bactericidal properties. Palmitoleic acid when applied directly to the skin can increase triglyceride concentration in the lipid barrier of the skin, one of the naturally occurring stratum corneum lipid components, as well as consequently enhancing the protective nature of the stratum corneum. Hyaluronic acid is naturally distributed throughout the human body where, among other noteworthy properties, it holds water in the intercellular matrix of dermal connective tissue and contributes to the elasticity of skin. www.herbal-powers.com /auskdi.html   (1634 words)

palmitoleic acid, oleic acid and inositol A diet enriched with oleic acid is associated with decreased susceptibility of oxidation of LDL,improvement of fluidity of the HDL which is associated with a greater ability to stimulate cholesterol efflux from cells, and an increase in the fluidity of LDL which decreases the atherogenicity. Two fatty acids with the double bond at the delta9 position, palmitoleic acid (omega7, delta9) and oleic acid (omega9, delta9), enhanced PG flux into the dermis and increased the dermal steady state level of PG. Oleic acid, besides exerting relatively minor effects on the quantitative and qualitative regulation of cholesterol levels, appears to interfere directly with the inflammatory response that characterizes early atherogenesis. www.anagen.net /palm.htm   (1003 words)

Clinic-Macadamia Fatty acid profiles for popcorn cooked in several oils were obtained for comparison because of public awareness and concern over high levels of saturated fat found in popcorn sold in theaters. Palmitoleic acid is a minor monounsaturated fatty acid in the human diet and in blood plasma. Palmitoleic acid (+4% en) behaves like a saturated and not a monounsaturated fatty acid in its effect on LDL cholesterol. www.raintree-health.co.uk /plants/macadamia.html   (335 words)

British Journal of Pharmacology - Effects of the gap junction uncoupler palmitoleic acid on the activation and ...   (Site not responding. Last check: 2007-10-31) Palmitoleic acid led to marked alterations of the activation pattern, expressed as the percentage of unchanged activation vectors (reduction from 32 to 10%, P<0.01, EC Figure 2). It may be noted that with increasing concentration of palmitoleic acid, the standard error or mean of the action potential duration is also slightly, although not significantly, increasing (see Table 2), which might reflect the increase in dispersion observed in the more compex whole heart preparation. Palmitoleic acid is supposed to block gap junction channels by incorporation into the plasma membrane thus disturbing the correct conformation of the channels and probably disturbing the docking as well. www.nature.com /bjp/journal/v128/n7/full/0702902a.html   (7579 words)

Marine Invertebrate Larval Biology   (Site not responding. Last check: 2007-10-31) Palmitelaidic acid, the trans isomer of highly active palmitoleic acid, was ineffective at inducing larval settlement. For example, although palmitoleic acid (16:1) was a potent inducer of larval settlement, oleic acid (18:1) was not, due to its greater molecular length. Linoleic (18:2) and linolenic acids (18:3) were active, however, because the additional cis double bonds act to twist and shorten these molecules to an overall shape similar to that of palmitoleic acid. people.uncw.edu /pawlikj/larvalbio.html   (1158 words)

monoenoic fatty acids Important cyclopentyl acids (tuberonic acid) and their glucosides belong to the jasmonate family that are likely to play a role in plant development (tuber-inducing factor in potatoes). These fatty acids were found in the esterified form in glyceride type lipids, amounted to 74 to 93% of the total fatty acids in the bacteria, and were shown to be formed from glucose and shikimic acid. As a furan fatty acid (10,13-epoxy-11-methyloctadeca-10, 12-dienoic acid) was detected in the cellular lipids of several marine bacteria (Shirasaka N et al., Biochim Biophys Acta 1995, 1258, 225), the authors propose that those detected in marine fish are derived from marine plants and/or intestinal bacteria of fishes. www.cyberlipid.org /fa/acid0002.htm   (5427 words)

Carboxylic Acid Reactivity Acetic acid is ten times weaker an acid than formic acid (first two entries in the second row), confirming the electron donating character of an alkyl group relative to hydrogen, as noted earlier in a discussion of carbocation stability. Reactions in which the hydroxyl group of a carboxylic acid is replaced by another nucleophilic group are important for preparing functional derivatives of carboxylic acids. Acid catalysis is necessary to increase the electrophilic character of the carboxyl carbon atom, so it will bond more rapidly to the nucleophilic oxygen of the alcohol. www.cem.msu.edu /~reusch/VirtualText/crbacid1.htm   (3475 words)

Monounsaturated Fatty Acids Prevent the Deleterious Effects of Palmitate and High Glucose on Human Pancreatic ...   (Site not responding. Last check: 2007-10-31) Ceramide is synthesized from long-chain fatty acids, and Palmitoleic and oleic acids increased expression of the antiapoptotic acid is correlated with de novo synthesis of ceramide (30). diabetes.diabetesjournals.org /cgi/content/full/52/3/726   (4897 words)

Biochemistry of Lipids The numeric designations used for fatty acids come from the number of carbon atoms, followed by the number of sites of unsaturation (eg, palmitic acid is a 16-carbon fatty acid with no unsaturation and is designated by 16:0). These two fatty acids cannot be synthesized from precursors in the body, and are thus considered the essential fatty acids; essential in the sense that they must be provided in the diet. Sphingosine is N-acetylated by a variety of fatty acids generating a family of molecules referred to as ceramides. www.indstate.edu /thcme/mwking/lipids.html   (825 words)

Gamma Linolenic Acid and Alpha Linolenic Acid - Revivogen Research The effect of gamma-linolenic acid is localized at the site of its application; topical application of gamma-linolenic acid did not affect the androgen-dependent growth of other organs such as testis, epididymis, seminal vesicle, and prostate. Certain unsaturated fatty acids, such as gamma-linolenic acid, are potent 5 alpha-reductase inhibitors, suggesting a linkage between unsaturated fatty acids and androgen action. The results of the binding assay and the enzymatic assay correlated well except for elaidic acid and linolelaidic acid, the trans isomers of oleic acid and linoleic acid respectively, which were much less active than their cis isomers in the binding assay but were as potent in the enzymatic assay. www.revivogen.com /research/gla.html   (778 words)

Ayaz & Kadioglu--Fatty acid changes in persimmon In the fruit, 11 fatty acids were identified and quantified: myristic acid (14:0), palmitic acid (16:0), palmitoleic acid (16:1), stearic acid (18:0), oleic acid (18:1), linoleic acid (18:2), linolenic acid (18:3), arachidic acid (20:0), behenic acid (22:0), lignoceric acid (24:0), and pentacosanoic acid (26:0). Four acids: palmitic acid (16:0), palmitoleic acid (16:1), linoleic acid (18:2), and linolenic acid (18:3) were identified as the major acids in significant amounts (P = 0.05) during development. Another four fatty acids: arachidic acid (20:0), behenic acid (22:0), lignoceric acid (24:0), and pentacosanoic acid (26:0), did not show the same increases or decreases in during development, but the levels were found to be significantly important in some stages. www.rsnz.org /publish/nzjchs/1999/31.php   (278 words)

Raztec - Azelaic acid for hair loss and balding A research report by Stamatiadis in 1988 suggested that azelaic acid (and combinations of it and zinc ion and vitamin B6) was a strong type I 5-alpha reductase (5-AR) inhibitor. The effects of zinc sulphate and azelaic acid on 5 alpha-reductase activity in human skin were studied using an in vitro assay with 1,2[3H]-testosterone as substrate. Azelaic acid was also a potent inhibitor of 5 alpha-reductase; inhibition was detectable at concentrations as low as 0.2 mmol/l and was complete at 3 mmol/l. www.raztec.com /azelaic.html   (542 words)

Chemoprevention & Various Oils: Breast Ca This report is on the transcriptional and DNA-binding properties of vegetable oils and fatty acids, and on the potentials of these compounds to prevent the formation of E2 epoxide. Similarly, unsaturated fatty acids, regardless of chain length and number of double bonds, were all able to prevent the formation of E2 epoxide as reflected by the loss of the ability of [3H]E2 to bind DNA. In contrast to vegetable oils, the results indicated that the unsaturated fatty acids palmitoleic, oleic, linoleic, linolenic and arachidonic acid could be activated by DMDO to inhibit nuclear RNA synthesis, and that the mono-unsaturated fatty acids (i.e. www.annieappleseedproject.org /chemvaroilbr.html   (364 words)

Clinic-MA Fatty acid profiles for popcorn cooked in several oils were obtained for comparison because of public awareness and concern over high levels of saturated fat found in popcorn sold in theaters. Palmitoleic acid is a minor monounsaturated fatty acid in the human diet and in blood plasma. Because macadamia oil is at least one potentially large source of palmitoleic acid, we tested its effect on plasma lipid levels against two other dietary fatty acids, oleic acid and palmitic acid. www.rain-tree.com /clinic/clinicma.htm   (656 words)

Oleic acid, an unsaturated fatty acid, in Cell Culture Fatty acids are esterified to a glycerol backbone to form a group of compounds known as mono-, di- and tri- glycerides (neutral fats). Natural fatty acids have their double bonds in the cis-configuration and are usually esterified to glycerol backbones to form complex lipids. Palmitic acid (16:0) is a precursor of stearic acid (18:0). www.sigmaaldrich.com /Area_of_Interest/Life_Science/Cell_Culture/Key_Resources/Media_Expert/Oleic_acid.html   (828 words)

Data Both experimental approaches demonstrated that oleic acid is the most efficacious UFA in overcoming the toxic effects of ethanol in growing yeast cells. We also showed that the most ethanol-tolerant transformant, which expresses the insect desaturase TniNPVE, produces twice as much oleic acid as palmitoleic acid in the absence of ethanol and undergoes a fourfold increase in the ratio of oleic acid to palmitoleic acid in response to exposure to 5% ethanol. These findings are consistent with the hypothesis that ethanol tolerance in yeast results from incorporation of oleic acid into lipid membranes, effecting a compensatory decrease in membrane fluidity that counteracts the fluidizing effects of ethanol. www.bionewsonline.com /l/d_data.htm   (452 words)

Carbonyl Group Formic acid and acetic acid have a sharp, pungent odor. Butyric acid, for example, is found in sweat, and the odor of rancid meat is due to carboxylic acids released as the meat spoils. Tartaric acid, for example, is a by-product of the fermentation of wine, and succinic, fumaric, malic, and oxaloacetic acid are intermediates in the metabolic pathway used to oxidize sugars to CO chemed.chem.purdue.edu /genchem/topicreview/bp/2organic/carbonyl.html   (1650 words)

Lipids The carboxylic acids with 12, 14, 16 and 18 carbon atoms are named from the Latin stem for the bay tree, laurel; the genus for the spice nutmeg, Myristica; the Latin stem for the palm tree, palma; and the Greek stem for the tallow used to make candles, stear. (Formic acid has an odor that is even sharper than acetic acid.) By the time the hydrocarbon chain has grown to a total of four carbon atoms, the odor of these compounds has taken a significant turn for the worse. So much attention is paid to the structures of the fatty acids in discussions of the chemistry of lipids that it is easy to miss an important point: Free fatty acids are seldom found in nature. chemed.chem.purdue.edu /genchem/topicreview/bp/1biochem/lipids6.html   (1217 words)
