Pathway of triglyceride biosynthesis during seed ripening

The investigations on the mode of triglyceride biosynthesis during ripening ofSolanum indicum, Salvadora persica, Mimusops hexandra, Aegle marmelos andMesua ferrea seeds, using chromatographic techniques have shown that these fats follow essentially a stepwise mechanism involving the formation of mono‐ and diglycerides as intermediate products. This is in agreement with the general in vitro enzymatic esterification by bacteriolipase, castor bean lipase and pancreatic lipase. The experimental basis of the Quantum mechanism of lipogenesis, postulated earlier forCocos nucifera and recently for many phanerograms, has been shown to be inadequate and hence the validity of Quantum hypothesis appears to be doubtful.
