Fatty acid methyl esters (FAME) are a type of fatty acid ester than can be produced by an alkali-catalyzed reaction between fats or fatty acids and methanol. The molecules in biodiesel are primarily FAMEs, usually obtained from vegetable oils by transesterification.
In some other studies, complementary techniques should be considered. Metabolic studies involve the knowledge of the intensity of labelling of molecular species with radioactive atoms while identification studies require the separation and quantification of hydroxylated, branched-chain, trans or conjugated fatty acids. These acids are almost entirely straight chain, even-numbered mono carboxylic acids containing from 8 to 22 carbons. Most new plants have been built in Southeast Asia which is the major source for coconut, palm and palm kernel oils. It is any of a class of organic compounds corresponding to the inorganic salts and formed from an organic acid and an alcohol.
Clinical analysis can determine the lengths, bonds, rings and branches of the FAME. To perform this analysis, a bacterial culture is taken, and the fatty acids extracted and used to form methyl esters. The volatile derivatives are then introduced into a gas chromatagraph, and the patterns of the peaks help identify the organism. This is widely used in characterizing new species of bacteria, and is useful for identifying pathogenic strains.
