Fatty acid thiokinase
WebMedium-chain fatty acids (MCFAs) are saturated or unsaturated fatty acids found at high concentrations in food such as coconut oil, with lauric acid (C12:0) representing ∼50% of its fat content. MCFAs are quickly oxidized by the liver and thus less obesogenic than LCFAs. Once the fatty acid is inside the mitochondrial matrix, beta-oxidation occurs by cleaving two carbons every cycle to form acetyl-CoA. The process consists of 4 steps. A long-chain fatty acid is dehydrogenated to create a trans double bond between C2 and C3. This is catalyzed by acyl CoA dehydrogenase to produce … See more 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, … See more Once inside the mitochondria, each cycle of β-oxidation, liberating a two carbon unit (acetyl-CoA), occurs in a sequence of four reactions: This process continues until the entire chain is cleaved into acetyl CoA units. The final cycle produces … See more β-Oxidation of unsaturated fatty acids poses a problem since the location of a cis bond can prevent the formation of a trans-Δ bond. These … See more The ATP yield for every oxidation cycle is theoretically a maximum yield of 17, as NADH produces 3 ATP, FADH2 produces 2 ATP and a full rotation of Acetyl-CoA in citric acid cycle produces 12 ATP. In practice it is closer to 14 ATP for a full oxidation cycle as … See more Free fatty acids cannot penetrate any biological membrane due to their negative charge. Free fatty acids must cross the cell membrane through specific transport proteins, … See more In general, fatty acids with an odd number of carbons are found in the lipids of plants and some marine organisms. Many ruminant animals form a large amount of 3-carbon propionate during the fermentation of carbohydrates in the rumen. Long-chain … See more Fatty acid oxidation also occurs in peroxisomes when the fatty acid chains are too long to be handled by the mitochondria. The same enzymes are used in … See more
