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.
