Branched chain fatty acids

Branched chain fatty acids (BCFA) are usually saturated fatty acids with one or more methyl branches on the carbon chain.[1][2] BCFAs are most often found in bacteria,[2] but can be found in Nattō[3], dairy[4], vernix caseosa of human infants and California sea lions[5] where they may play a role in fostering the development of their intestinal microbiota.[1] Another waxy animal material containing BCFAs is lanolin.[2]
