What other necessary precursors can be / are generated as part of the transport process? 0O 5. anabolic pathways are converted to fatty acids and stored as triacylglycerols. In this mini-review, we describe recent progress that has been made with the yeast Saccharomyces cerevisiae in understanding formation of TAG and its cell biological role. Triacylglycerol is composed of three fatty acyl groups esterified to a glycerol backbone at the sn-1, sn-2 and sn-3 positions.In higher plants, triacylglycerol is the predominant component of the oil of the seeds or fruits of oleaginous plants and primarily serves as an energy store to support the growth of the young seedling during the early stages of germination.

View the article PDF and any associated supplements and figures for a period of 48 hours. 16.9 Synthesis of Triacylglycerols (TGs) and Glycerophospholipids (GPLs) • Most fatty acids in cells are found in esterified forms as TGs or GPLs • Phosphatidic acid (phosphatidate) is an intermediate in the synthesis of TGs and GPLs • Glycerol 3-phosphate is acylated by fatty acyl CoA molecules Prentice Hall c2002 Chapter 16 62 How is it transported to the site of fatty acid biosynthesis? The fatty acids synthesized in the liver are used for triacylglycerol, phosphoglyceride, and sphingolipid synthesis. Fatty acids are synthesized mainly in the liver in humans, with dietary glucose serving as the major source of carbon. Where is it generated?
