Heptadecanoic acid, or margaric acid, is a saturated fatty acid. It occurs as a trace component of the fat and milkfat of ruminants, but it does not occur in any natural animal or vegetable fat at concentrations over half a percent. Salts and esters of heptadecanoic acid are called heptadecanoates (Wikipedia). Heptadecanoic acid is found in many foods, some of which are dandelion, potato, ginger, and green bean. Heptadecanoic acid is a constituent of Erythrina crista-galli trunkwood and bark. Common constituent of lipids, e.g. present in Physalia physalis (Portuguese-man-of-war). Heptadecanoic acid is a fatty acid of exogenous (primarily ruminant) origin. Many "odd" length long chain amino acids are derived from the consumption of dairy fats (milk and meat). Heptadecanoic acid constitutes 0.61\\\\% of milk fat and 0.83\\\\% of ruminant meat fat. The content of heptadecanoic acid in the subcutaneous adipose tissue of humans appears to be a good biological marker of long-term milk fat intake in free-living individuals in populations with high consumption of dairy products. (PMID 9701185). Heptadecanoic acid is an odd chain saturated fatty acid (OCS-FA). Heptadecanoic acid is associated with several diseases, including the incidence of coronary heart disease, prediabetes and type 2 diabetes as well as multiple sclerosis[1].
