Fatty Acid Biosynthesis 2 Citrate Shuttle • FAs are synthesized in the cytoplasm from acetylCoA • AcetylCoA generated from pyruvate by the action of PDH and by β-oxidation of fatty acids is in the mitochondria. • For fatty acid biosynthesis, acetylCoA has to be transported from the mitochondria to the cytoplasm. This is done via a Fatty acids are synthesized by step-wise addition of two-carbon units in the form of acetyl-CoA. It may be remembered that acetyl-CoA is an important intermediate, produced by decarboxylation of pyruvic acid in course of glucose breakdown pathway. Although long-chain fatty acids are synthesized by addition of two-carbon units at a time, this two-carbon unit is donated not by acetyl-CoA directly, but by a carboxylated product of acetyl-CoA viz. malonyl-CoA.

In fatty acid synthesis, acetyl‐CoA is the direct precursor only of the methyl end of the growing fatty acid chain. All the other carbons come from the acetyl group of acetyl‐CoA but only after it is modified to provide the actual substrate for fatty acid synthase, malonyl‐CoA. Malonyl‐CoA contains a 3‐carbon dicarboxylic acid, malonate, bound to Coenzyme A. Malonate is formed from acetyl‐CoA by the addition of CO 2 using the biotin cofactor of the enzyme acetyl‐CoA carboxylase.

The anaerobic synthesis is carried out by the enzymatic complex synthesizing the saturated fatty acids with the following variant: the 10 carbon atom β-hydroxyacyl-ACP will be dehydrated (see fig. 5-19) to give simultaneously a α, β-dehydroacyl-ACP (C 10, ∆ 2) and a β, γ-dehydroacyl-ACP (C 10, ∆ 3 ).

Lecture 10: Fatty Acid Synthesis

I bought a roll of unexposed film that expired in 1974 on eBay, but when it came it turned out the roll was already exposed! So I sent it off to the lovely folks at Harman Lab who took on the challenge of developing this 45 year old roll of film. Here are the scans, completely unaltered in all their psychedelic glory.
