 Palmitic Acid - LoveToKnow 1911
PALMITIC ACID, n-Hexadecylic Acid, Ch3(Ch2)14c02h, an organic acid found as a glyceride, palmitin, in all animal fats, and partly as glyceride and partly uncombined in palm oil.
It is most conveniently obtained from olive oil, after removal of the oleic acid, or from Japanese beeswax, which is its glyceride.
Artificially it may be prepared by heating cetyl alcohol with soda lime to 270° or by fusing oleic acid with potassium hydrate.

 Evaporation of Fatty Acids and the Formation of Ghost Images by Framed Oil Paintings
The fatty acid compositions in the sand bath ghosts were proportional to the levels of free fatty acids present in the paint samples, but in every instance the ghosts were enriched in the more volatile, lower-boiling species.
The TG data are in broad agreement with the observed high levels of palmitic acid in ghost images, although strict comparison between half-time estimates and the composition of ghost images from the test paints is not possible due to limitations in the design of the experimental apparatus.
Presumably, the fatty acids were released either from the oil matrix through hydrolysis of the glyceride ester backbone or else from decomposition of pigment extenders (such as stearates), and once liberated were able to migrate through the paint and deposit on the surface.

 U.S. FDA/CFSAN: Agency Response Letter: GRAS Notice No. GRN 000192
High 2-palmitic acid vegetable oil is prepared by the enzymatic modification of palm stearin (composed mainly of tripalmitin) to yield an ingredient that more closely resembles human milk triglycerides in its fatty acid positional distribution relative to traditional vegetable oils.
The high 2-palmitic acid vegetable oil is produced by enzymatic esterification of randomized palm stearin with fatty acids (primarily oleic acid) from either palm kernel oil or high oleic sunflower oil.
The palmitic acid residues on the palm stearin triglycerides are replaced by oleic acid residues at the sn-1 and sn-3 positions, leaving the sn-2 fatty acids (primarily palmitic acid as well as some oleic acid) unaltered.

Hydrogenation is used to remove the unsaturation of fatty acids in order to increase the oxidative stability of oils and to raise their melting points, which allows for the modification of their physical properties allowing for a broader range of usage in the food industry.
The unsaturated fatty acids are 43% oleic acid (monunsaturates) and 12% linoleic acid (polyunsaturates).
