Desaturation of oleoyl groups in envelope membranes from spinach chloroplasts.

Abstract

Envelope membranes isolated from chloroplasts of spinach (Spinacia oleracea) desaturate oleoyl groups in monogalactosyl diacylglycerol to linoleoyl groups. The desaturation requires NADPH in combination with ferredoxin and is not restricted to monogalactosyl diacylglycerol, since it is also observed in biosynthetic intermediates as, for example, in phosphatidic acid. This indicates a certain degree of unspecificity of the oleate desaturase in isolated envelope membranes. Lipid desaturation is another important function of chloroplast envelopes.
