The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]

, 1994
The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown
