Fa synthesis

• What is fatty acid synthesis?

  The enzymes of fatty acid synthesis are packaged together in a complex called as fatty acid synthase (FAS). The product of FAS action is palmitic acid. (16:0). Modifications of this primary FA leads to other longer (and shorter) FA and unsaturated FA. The fatty acid molecule is synthesized 2 carbons at a time

• What is de novo fatty acid synthesis?

  DE NOVO SYNTHESIS Fat synthesis within the mammary gland (starting from scratch) Acetate is the main carbon source β-hydroxybutyrate (BHBA) can also serve as the initial 4 carbons Both absorbed through cell’s basolateral membrane Fatty acids are built 2 carbons at a time 16 carbon limit DE NOVO FATTY ACID SYNTHESIS

• What is the end product of -oxidation of FAS?

  The end product of β-oxidation of FAs is acetyl-CoA, which is a key metabolite for energy production via mitochondrial respiration and for the synthesis of carbon skeletons via the glyoxylate cycle and gluconeogenesis.

• What is the primary source of carbons for FA synthesis in ruminants?

  In ruminants, dietary and carbohydrates fats are generally metabolized in the rumen so that the primary source of carbons for FA synthesis by the mammary gland are acetate and BHBA Glucose is limiting in ruminants

  Fatty Acid Synthesis • Occurs mainly in liver and adipocytes (mammals) • FA synthesis and degradation occur by two completely separate pathways • When glucose is plentiful, large amounts of acetyl CoA are produced by glycolysis and can be used for fatty acid synthesis • Glucose oxidation in the pentose phosphate

  precursor for FA synthesis. In oilseeds, hexoses generated by sucrose cleavage are metabolized into pyruvate for FA synthesis via the glycolysis pathway, which operates in parallel in both the cytosol and the plastid (8; 15; 16). This parallel pathway can interact through the action of highly
