BIO 360 Chapter Notes - Chapter 21: Triglyceride, Glycerol, Phospholipid
Document Summary
Most glycerol 3- phosphate comes from siphoning off dihydroxyacetone phosphate idhap) from glycolysis. V1 a glycerol 3- phosphate dehydrogenase some glycerol 3 phosphate is made from glycerol. V1 a glycerol kinase minor pathway in liver + kidney. Fatty acyl group is activated by formation of the fatty acyl-coa then transferred to ester linkage with l -glycerol 3-phosphate , Phosphatldlc acid (2) at c-2 of the glycerol molecule . Intermediate product with only one esterified fatty acyl group is iysophosphatldlc acid . To conserve space in subsequent figures , both fatty acyl groups of glycerophospholipids , + all three acyl groups of tri acylglycerols are shown projecting to the right . Phosphatldlc acid precursor to tags + phospholipids fatty acids attached by acyltransferases releases coa. It can then be made into tri acyl glycerol or phospholipid. Phosphatldlc acid phosphatase (lip in) removes the 3- phosphate from the phosphatldlc acid yields 1,2 - diacylglycerol.
