Secondary Products Originating from L-Valine

L-Valine is a branched chain amino acid with 5 C-atoms. Most secondary products formed from L-valine still contain this isopentane skeleton (cf. the formulas of pantoic acid and erythroskyrin). 

Secondary products derived from L-valine are synthesized in microorganisms, plants and animals. 

L-valine is built by a pathway resembling L-isoleucine formation (Fig. 196). It may be degraded to succinyl CoA, as shown in Fig. 197.
