Fatty acid synthesis khan academy. What Ive drawn out here are three compartments found inside of a cell and what I want to go ahead and do now is kind of label what I have to run out here because these three compartments are going to be very important when discussing the three kind of major phases involved in oxidizing and extracting ATP from fatty acids inside of the cells so starting up here this compartment Im going to.

Fatty Acid Synthesis Problems. 2-46-71013-1421-24 281 Stages of FA Synthesis 1. Transfer of acetyl-CoA from mitochondria to cytosol.
Five step elongation cycle of FA synthesis via ACP intermediates. Fatty Acid Biosynthesis 4 Fatty Acid Synthase FAS FAS is a polypeptide chain with multiple domains each with distinct enzyme activities required for fatty acid biosynthesis. Recall that CoA is used as an activator for β-oxidation.
For fatty acid biosynthesis the activator is a protein called the acyl carrier protein ACP. The main ATP source is AcCoA that udergoes Krebs Cycle which is sythesised from palmic acid oxidation. Whilst oxidation of a two carbon segment on palmic acid involves strippindg off hydrogens from that segment.
Thus NADH is sythesised which is processed to ATP through Electron Transport Chain. In acyl transfer reaction the fatty acid residue is transferred back to the -SH group to which the acetyl group was transferred in initiation reaction. The cycle is repeated again and again with malonyl transfer condensation etc till the tatty acid residue consists of up to 16 to 18 C atoms.
How do we extract ATP from fat. How much ATP do we produce. Structure of fatty acids Tuesday June 14 2016 Rajesh Chaudhary 2 3.
Some facts De Novo Synthesis of Fatty acids Large portion of fatty acid supplied in our body is through diet. In adults fatty acid synthesis occurs in primarily in liver and lactating. The pathway is called fatty acid synthesis atleast in my text book glucose is broken down into pyruvate which in turn stimulates the TCA cycle Citrate gets shuttled out to the cytoplasm gets converted back into Acetyl- CoA which then though a few more steps gets converted into Fatty acids 3.
Fatty acid synthesis involves the de novo assembly of acetate into saturated fatty acids as well as the desaturation and elongation of the dietary essential fatty acids linoleic acid C182n-6 and α-linolenic acid C183n-3 to highly unsaturated 20- and 22-carbon fatty acids essential to reproduction cell differentiation inflammation and cognition. Fatty Acid Oxidation - Part I. If playback doesnt begin shortly try restarting your device.
The role of glycolysis and the pentose-phosphate pathway in fatty acid synthesis. Acetyl CoA for fatty acid synthesis comes mostly from glycolytic breakdown of glucose. Glucose Yields Acetyl CoA – Schematic This process is somewhat roundabout.
Glucose is first degraded to pyruvate by aerobic glycolysis in the cytoplasm.
