Isolation and characterization of 2-(β,D-glucopyranosyl)-4-alanyl-3-Isoxazolin-5-one : a second UV-sensitive heterocyclic α-amino acid from Pisum sativum L
No full textIn addition to 2-alanyl-3-isoxazolin-5-one (I) an other UV-sensitive heterocyclic α-amino acid (III) has been isolated and purified from pea seedlings. Some properties of III are compared with those of synthetic isoxazolinone derivatives and with those of I. The chemical structure was analyzed by chemical methods and by spectroscopy. The structure was found to be: 2-(β,D-glucopyranosyl)-4-alanyl-3-isoxazolin-5-one
