Both lipid synthesis and composition in oil bodies and microsomes of olive fruit at the first stage of development have been studied. The rate of fatty-acid synthesis in isolated oil bodies was saturated by 4.0 microM [2-14C]-malonyl-CoA. The fatty-acids synthesized of phospholipids and neutral lipids were saturated and monounsaturated. Neutral lipids, galactolipids and, above all, phospholipids were the major acyl-lipid components of microsomal fraction, oleic and palmitic being their principal fatty-acids. When the lipids of microsomes were labelled in vivo with [1-14C]-acetate, phospholipids and neutral lipids exhibited a higher biosynthesis rate relative to the galactolipids. The increase in saturated and monounsaturated fatty-acid synthesis in microsomes, was also accompanied by an important [1-14C]-acetate incorporation into polyunsaturated acids. The data presented here, in conjunction with our previous morphological results, suggest the possibility that olive fruit oil bodies could contain the necessary enzymes for the reserve lipid biosynthesis.
