FIG. 6.
Schematic representation of branched-chain fatty acid biosynthesis with leucine, isoleucine, and valine leading to iso- and anteiso-branched fatty acid products, respectively. a, a soluble branched-chain amino acid amino transferase; b, NAD- and CoA-dependent branched-chain α-keto-acid decarboxylase. The underlined metabolites were supplied externally, as indicated in the text. This scheme is adapted from the one presented by Kaneda (20).
