Synthesis of fatty acids occurs in the cytoplasm, and is catalyzed by fatty acid synthase. In animals, fatty acid synthase is a homodimer, with each chain approximately 250,000 Daltons in size. The two chains are linked head to tail. All of the components of fatty acid synthase, including ...
Fatty acid synthesis occurs in the cytosol but is essentially the reverse of β-oxidation of fatty acids (although it employs a separate set of enzymes), whereby fatty acids are synthesized from the successive additions of 2C acetyl-CoA followed by reduction. Acetyl-CoA is formed in the mitoch...
As fatty acid synthesis occurs in the cytosol, we monitored the cytosolic content of NADPH using the genetically encoded fluorescent iNAP sensor21,22. Figure 2a, b show that the NADPH level decreased by about 30% in FASN-overexpressing adipocytes. We also used a HYPER sensor23 to monitor cellu...

coli, a number of the genes are organized in the fab cluster. The bacterial acetyl-CoA carboxylase represents an example for a bacterial enzyme complex that is involved in fatty acid biosynthesis. Studies of the fatty acid synthase of Archaea are rare, because the de novo synthesis of fatty ...
(NASH). A form of liver disease that occurs when excess fat is present in the liver accompanied by inflammation and possibly fibrosis. Triglyceride lipolysis The breakdown of a triglyceride molecule to produce one glycerol molecule and three fatty acid molecules. Hepatic portal vein Blood vessel tha...
Free sterols and their fatty acid esters in Saccharomyces cerevisiae were separated by TLC, and the sterol contents and compositions of both fractions were analyzed by GLC. During respiratory adaptation of anaerobically grown yeast cells, larger amounts of esterified sterols were accumulated than of fr...

17. What occurs in the second stage of fatty acid oxidation? A. Conversion of acetyl-CoA into glucose B. Oxidation of acetyl-CoA to CO2 in the citric acid cycle C. Conversion of acetyl-CoA into ketone bodies D. Hydrolysis of acetyl-CoA Answer: B 18. How does malonyl-CoA affect fatty...
In moving from Step 2 to Step 3, the acyl group at the first sulfhydryl group attacks the malonyl group. The attack occurs at the central carbon of the malonyl group. This results in the discharge of CO2 and elongation of the growing fatty acid chain by two carbons. At this point, the...
