Desaturation of linoleic acid from exogenous lipids by isolated chloroplasts.

Abstract

When [14C]diacylgalactosylglycerol was added to isolated pea or lettuce chloroplasts linolenate synthesis was seen. The desaturation of [14C]linoleate in diacylgalactosylglycerol to [14C]linolenate was stimulated by the addition of a soluble protein fraction containing lipid-exchange activity. Other [14C]acyl lipids were ineffective, except that [14C]phosphatidylcholine in the presence of UDP-galactose and sn-glycerol 3-phosphate could also supply [14C]linoleate for desaturation. These results are consistent with a role of diacylgalactosylglycerol in linolenate synthesis, as indirectly suggested by labelling experiments.
