		Stearic acid is prepared by treating animal fat with water at a high pressure and temperature, leading to the hydrolysis of triglycerides.
		In fireworks, stearic acid is often used to coat metal powders such as aluminium and iron.
		Stearic acid undergoes the typical reactions of unsaturated carboxylic acids, notably reduction to stearyl alcohol, and esterification with a range of alcohols.

	Stearic Acid
		Stearic acid is a saturated fat that's mainly in animal products.
		It's also in some plant foods like chocolate. It's very stable in storage and during frying. A relatively large percentage of stearic acid consumed is converted to oleic acid (a monounsaturated fat).
		Stearic acid is used to form margarines, shortenings, spreads, and as a cream base for baked products. Even though stearic acid is a saturated fat, studies have suggested that it has little effect on blood cholesterol levels, because such a high proportion is converted to oleic acid.

	Stearic Acid
		Stearic acid is a saturated acid, since there are no double bonds between neighbouring carbon atoms.
		Sodium stearate is a typical example of a detergent or soap, since it contains a long hydrocarbon 'tail' (magenta) and a carboxylic acid 'head' group (blue).
		Potassium salts of fatty acids are also used, in combination with excess stearic acid, to give a slow-drying lather for shaving soap.

	Ingredients -- Stearic acid
		Stearic acid is the most common of the long-chain fatty acids.
		Stearic acid is a member of the group called fatty acids.
		The long hydrocarbon chain of the stearic acid is hydrophobic, attracted to oils and fats instead of water.

	The Dimensions of a Molecule
		When stearic acid is added to water its molecules tend to accumulate on the surface of the water with the carboxyl group dissolved in water and the hydrocarbon end pointing away from the surface as the nonpolar ends are attracted to each other but are uncomfortable in the water..
		The thickness of the monolayer is equal to the length of the stearic acid molecule.
		Assuming that the length of a stearic acid molecule is approximately the same as that of a hydrocarbon molecule containing 18 carbon atoms, estimate the length of the stearic acid molecule, and compare the result to your experimental value.

	Stearic acid Summary
		Stearic acid, also called octadecanoic acid, is one of the useful types of saturated fatty acids that comes from many animal and vegetable fats and oils.
		Stearic acid is prepared by treating animal fat with water at a high pressure and temperature, leading to the hydrolysis of triglycerides.
		Stearic acid is used to harden soaps, particulary those made with vegetable oil, that otherwise tend to be very soft.

	Stearic Acid
		Stearic acid is an example of a fatty acid.
		Fatty acids are long molecules consisting of a hydrocarbon chain with a carboxylic acid group (-COOH) at the end.
		When a fatty acid is placed on a water surface, the hydrophilic heads of the molecules are attracted to the water.

	The Dimensions of a Molecule
		The purpose of this experiment is to determine the length and cross sectional area of a molecule of stearic acid.
		When stearic acid is added to water its molecules tend to accumulate on the surface of the water with the carboxyl group dissolved in water and the hydrocarbon end pointing away from the surface.
		The cross sectional area of a stearic acid molecule is obtained from the total area of the film and the number of molecules in the film.

		The stearic acid molecules line up with their hydrophilic acid heads attached to the surface of the water, represented here by the horizontal line, and their hydrophobic tails sticking up away from the surface of the water.
		First of all, notice that the length of a molecule of stearic acid is the thickness of the thin film.
		Using the volume of stearic acid in a drop and the approximate volume of a stearic acid molecule from #8, find the number of molecules of stearic acid in one of your films.

		Interpretive Summary: Stearic acid is the predominant fatty acid in triacylglycerols of beef fat and coconut oil (present as the ester).
		Solids researchers have proposed that stearic acids exist in a cubic phase, i.e., they self associate in a group of parallel aligned molecules.
		We demonstrate that the same explanation holds for predicting the solubility of stearic acid in four of five structurally different solvents.

	NEJM -- Effect of dietary stearic acid on plasma cholesterol and lipoprotein levels
		We studied the metabolic effects of stearic acid (18:0) on plasma lipoprotein levels in 11 subjects during three dietary periods of three weeks each.
		The oleic acid content of plasma triglycerides and cholesteryl esters increased significantly during the high-stearic-acid period, suggesting that stearic acid is rapidly converted to oleic acid.
		We conclude that stearic acid appears to be as effective as oleic acid in lowering plasma cholesterol levels when either replaces palmitic acid in the diet.
