1、Chapter 25: Fatty Acid Biosynthesis,CH234 Bruce A. Hathaway,1,Acetyl Coenzyme A,Acetyl Coenzyme A is the starting material for fatty acid biosynthesis. It is derived from metabolism of carbohydrates, fats and some amino acids. The two-carbon piece provides the carbons for the new fatty aci...
Activation by Malonyl-CoA Acetate Units are Activated for Transfer in Fatty Acid Synthesis by Malonyl-CoA Fatty acids are built from 2-C units - acetyl-CoA Acetate units are activated for transfer by conversion to malonyl-CoA Decarboxylation of malonyl-CoA and reducing power of NADPH drive chain...

Currently, the PPTase has been proved to be involved in the biosynthesis of polyunsaturated fatty acids (PUFAs) via a polyketide synthase (PKS) pathway in Thraustochytrids, while its characteristics are not clarified. Results: Here, the heterologous PPTase gene (pfaE) from bacteria was first ...
Cholesterol Biosynthesis Stage 1: Condensation of Mevalonate from Acetate Final step in β-oxidation of fatty acids in reverse (cytosolic) Aldol condensation at C3 carbonyl to form HMG-CoA Reduction of HMG-CoA Committed step in biosynthesis of isoprenes Requires 2 NADPH for reduction of carboxylate...
In the PG, an intriguing question is several fatty acyls of various chain lengths and isomeric forms. The present study describes an extensive search of the Spodoptera exigua PG that revealed two active pgFAR candidates, and a heterologous gene expression study in yeast demonstrated that each FAR...
Complex polyketides are typically associated with microbial metabolism. Here, we report that animals also make complex, microbe-like polyketides. We show there is a widespread branch of fatty acid synthase- (FAS)-like polyketide synthase (PKS) proteins,
Heart Muscle Heart exclusively aerobic and has no glycogen stores. Fatty acids are the hearts primary fuel source. Can also use ketone bodies. Doesn’t like glucose Liver Major function is to provide fuel for the brain, muscle and other tissues Metabolic hub of the body Most compounds absorb ...
