12-methyl Myristic acid, a methylated fatty acid, can be found in various sources such as bacteria, dairy products, saltwater fish (both wild-caught and farm-raised), and mouse subcutaneous adipose tissue. In laboratory studies, 12-methyl myristic acid (0.625-40 μg/ml) has demonstrated antifouling properties by reducing the settlement of H. elegans larvae in a concentration-dependent manner. It is worth noting that the levels of 12-methyl myristic acid are lower in mice fed a high-fat diet compared to those fed a standard diet. 12-methyltetradecanoic acid, on the other hand, is a saturated fatty acid with a branched structure. It consists of tetradecanoic acid carrying a 12-methyl substituent. This compound falls into the category of long-chain fatty acids and belongs to the group of branched-chain saturated fatty acids.
