title: Capsinoid is biosynthesized from phenylalanine and valine in a non-pungent pepper, Capsicum annuum L. cv. CH-19 sweet.
abstract: The biosynthetic pathway of capsinoid in 'CH-19 Sweet' was investigated. [(3)H]Valine and [(14)C]phenylalanine were injected into the fruits of the intact plant. Both of radioactivities were detected in capsinoid fractions. (14)C radioactivity was observed in phenylpropanoid compounds, and in vanillin, vanillylamine, vanillyl alcohol, and vanillic acid. We confirmed that capsinoid is biosynthesized from phenylalanine and valine.
