essay on beta oxidation
Answers
Answer:
Beta-oxidation consists of four steps:
1) Dehydrogenation catalyzed by acyl-CoA dehydrogenase, which removes two hydrogens between carbons 2 and 3.
2) Hydration catalyzed by enoyl-CoA hydratase, which adds water across the double bond.
3) Dehydrogenation catalyzed by 3-hydroxyacyl-CoA dehydrogenase, which generates NADH.
4) Thiolytic cleavage catalyzed beta-ketothiolase, which cleaves the terminal acetyl-CoA group and forms a new acyl-CoA which is two carbons shorter than the previous one.
The shortened acyl-CoA then reenters the beta-oxidation pathway.
Answer:
β-Oxidation (in which all reactions involve the β-carbon of a fatty acyl-CoA) is a spiral consisting of four sequential steps, the first three of which are similar to those in the TCA cycle between succinate and oxaloacetate. ... A double bond is produced between the α- and β-carbons, and an enoyl-CoA is formed.
Beta oxidation breaks down fatty acids to produce energy. In biochemistry and metabolism, beta-oxidation is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which are co-enzymes used in the electron transport
Fatty acid oxidation is the mitochondrial aerobic process of breaking down a fatty acid into acetyl-CoA units. ... The bond is broken between the second carbon/beta carbon and the third carbon/gamma carbon, hence the name beta oxidation. This process provides energy from fats.
