Abstract

The biosynthesis of chlorophyll a and chlorophyll b from (2__R__,3__R__)‐ and (2__S__,3__S__)‐5‐amino[2,3‐^14^C~2~,2,3‐^2^H~2~,2,3‐^3^H~2~]levulinic acid in greening barley has established that chlorophyllide a oxidase catalyses the transformation of the methyl group at C(7) of chlorophyllide a into the CHO group of chlorophyllide b with the loss of H^Si^ from the 7‐(hydroxymethyl)chlorophyllide intermediate.
