Saturated fatty acid of Caproic acid

Caproic acid CH3(CH2)4COOH is also known as Hexanoic acid, Capronic acid. Caproic acid derived its name from Latin word caper, which means goat.

It is a colorless oily liquid smelling of cheese. It is a fatty acid found as a triglyceride in cow and goat butter, and in coconut and palm oils.

Caproic acid has and heavy, acrid-acid, fatty-acid odor, often described as sweat-liked. Caproic acid is medium chain triglycerides (MCT). MCTs are widely used for parenteral nutrition in individuals requiring supplemental nutrition and are being more widely used in foods, drugs and cosmetics; they are essentially non-toxic.

This fatty acid is used as flavour ingredient and very characteristic of human sweat. It is an important ingredient in Italian cheese flavors and is also important in the profile of fermentation products.

Lignoceric acid

Lignoceric acid, also known as tetracosanoic acid, is a normal carboxylic acid, a very long chain fatty acid (VLCFA). Lignoceric acid is a constituent of cerebrosides and of sphingomyelin.

Lignoceric acid, a 24-carbon saturated (24:0) fatty acid and in mammals, it is synthesized during brain development.

The fatty acids of peanut oil contain small amounts of lignoceric acid (1.1% – 2.2%). This fatty acid is also a byproduct of lignin production. Reduction of lignoceric acid yields lignoceryl alcohol.

The tamarind kernel oil from India is unique in having a large proportion (22.3%) of the saturated fatty acid, lignoceric acid. The only other oil that has been reported to contain substantial quantities of lignoceric acid comes from the seed of coral wood.

Saturated fatty acid: Stearic acid

Stearic acid (systematic name, octadecanoic acid, CH3 (CH2) 16COOH) is a long-chain fatty acid consisting of 18 carbon atoms without double bonds. It is classified as a saturated fatty acid (SFA), both biochemically, and for purposes of food labeling and dietary recommendations.

Also known as n-octade- canoic acid, stearic acid is used in the preparation of metallic stearates, as a lubricant, and in pharmaceuticals.

In nature stearic acid occurs primarily as a mixed triglyceride, or fat, with other long-chain acids and as an ester of a fatty alcohol.

Stearic acid, as a percent of total fat calories, is fairly constant in beef, pork, lamb and veal at approximately 9% to 12%, with poultry lower at approximately 6% to 7%. Common cooking oils contain relatively small amounts of stearic acid, 2% to 4%, although hydrogenation of vegetable oils for the production of shortening and margarine can increase the concentration. Stearic acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products.

Stearic acid has been used in the development of a drug delivery system, because it is considered to be inert, inexpensive, and biocompatible, as well as of a low toxicity. In addition, stearic acid has been used for a cyclosporine-A drug carrier system, and for masking the bitter taste of pharmaceutical compounds.
