3-Oxododecanoyl-CoA
C33H56N7O18P3S (963.2615266000001)
3-oxododecanoyl-coa, also known as 3-oxolauroyl-CoA is an acyl-CoA or acyl-coenzyme A. More specifically, it is a 3-oxododecanoic acid thioester of coenzyme A. 3-oxododecanoyl-coa is an acyl-CoA with 12 fatty acid group as the acyl moiety attached to coenzyme A. Coenzyme A was discovered in 1946 by Fritz Lipmann (Journal of Biological Chemistry (1946) 162 (3): 743–744) and its structure was determined in the early 1950s at the Lister Institute in London. Coenzyme A is a complex, thiol-containing molecule that is naturally synthesized from pantothenate (vitamin B5), which is found in various foods such as meat, vegetables, cereal grains, legumes, eggs, and milk. More specifically, coenzyme A (CoASH or CoA) consists of a beta-mercaptoethylamine group linked to the vitamin pantothenic acid (B5) through an amide linkage and 3-phosphorylated ADP. Coenzyme A is synthesized in a five-step process that requires four molecules of ATP, pantothenate and cysteine. It is believed that there are more than 1100 types of acyl-CoA’s in the human body, which also corresponds to the number of acylcarnitines in the human body. Acyl-CoAs exists in all living species, ranging from bacteria to plants to humans. The general role of acyl-CoA’s is to assist in transferring fatty acids from the cytoplasm to mitochondria. This process facilitates the production of fatty acids in cells, which are essential in cell membrane structure. Acyl-CoAs are also susceptible to beta oxidation, forming, ultimately, acetyl-CoA. Acetyl-CoA can enter the citric acid cycle, eventually forming several equivalents of ATP. In this way, fats are converted to ATP -- or biochemical energy. Acyl-CoAs can be classified into 9 different categories depending on the size of their acyl-group: 1) short-chain acyl-CoAs; 2) medium-chain acyl-CoAs; 3) long-chain acyl-CoAs; and 4) very long-chain acyl-CoAs; 5) hydroxy acyl-CoAs; 6) branched chain acyl-CoAs; 7) unsaturated acyl-CoAs; 8) dicarboxylic acyl-CoAs and 9) miscellaneous acyl-CoAs. Short-chain acyl-CoAs have acyl-groups with two to four carbons (C2-C4), medium-chain acyl-CoAs have acyl-groups with five to eleven carbons (C5-C11), long-chain acyl-CoAs have acyl-groups with twelve to twenty carbons (C12-C20) while very long-chain acyl-CoAs have acyl groups with more than 20 carbons. 3-oxododecanoyl-coa is therefore classified as a long chain acyl-CoA. The oxidative degradation of fatty acids is a two-step process, catalyzed by acyl-CoA synthetase/synthase. Fatty acids are first converted to their acyl phosphate, the precursor to acyl-CoA. The latter conversion is mediated by acyl-CoA synthase. Three types of acyl-CoA synthases are employed, depending on the chain length of the fatty acid. 3-oxododecanoyl-coa, being a long chain acyl-CoA is a substrate for long chain acyl-CoA synthase. The second step of fatty acid degradation is beta oxidation. Beta oxidation occurs in mitochondria and, in the case of very long chain acyl-CoAs, the peroxisome. After its formation in the cytosol, 3-Oxododecanoyl-CoA is transported into the mitochondria, the locus of beta oxidation. Transport of 3-Oxododecanoyl-CoA into the mitochondria requires carnitine palmitoyltransferase 1 (CPT1), which converts 3-Oxododecanoyl-CoA into 3-oxododecanoylcarnitine, which gets transported into the mitochondrial matrix. Once in the matrix, 3-oxododecanoylcarnitine is converted back to 3-Oxododecanoyl-CoA by CPT2, whereupon beta-oxidation can begin. Beta oxidation of 3-Oxododecanoyl-CoA occurs in four steps. First, since 3-Oxododecanoyl-CoA is a long chain acyl-CoA it is the substrate for a long chain acyl-CoA dehydrogenase, which catalyzes dehydrogenation of 3-Oxododecanoyl-CoA, creating a double bond between the alpha and beta carbons. FAD is the hydrogen acceptor, yielding FADH2. Second, Enoyl-CoA hydrase catalyzes the addition of water across the newly formed double bond to make an alcohol. Third, 3-hydroxyacyl-CoA dehydrogenase oxidizes the alcohol group to a ket... 3-Oxododecanoyl-CoA is a human metabolite involved in the fatty acid elongation in mitochondria pathway. The enzyme acetyl-CoA C-acyltransferase catalyzes the formation of this metabolite from Acetyl-CoA. [HMDB]

3-Oxooctanoyl-CoA is the substrate of the acetyl-CoA C-acyltransferase/oxoacyl-CoA thiolase A (EC 2.3.1.16, SCP2/3-oxoacyl-CoA thiolase) present in peroxisomes from normal liver. Peroxisomes beta -oxidize a wide variety of substrates including straight chain fatty acids, 2-methyl-branched fatty acids, and the side chain of the bile acid intermediates di- and trihydroxycoprostanic acids. Peroxisomes contain several beta -oxidation pathways with different substrate specificities; or example, straight chain acyl-CoAs are desaturated by palmitoyl-CoA oxidase, and their enoyl-CoAs are then converted to 3-oxoacyl-CoAs by MFP-1, which forms (hydration) and dehydrogenates L-3(3S)-hydroxyacyl-CoAs; for example, straight chain acyl-CoAs are desaturated by palmitoyl-CoA oxidase (23), and their enoyl-CoAs are then converted to 3-oxoacyl-CoAs by 3-hydroxyacyl-CoA dehydrogenase (EC 1.1.1.35), which forms (hydration) and dehydrogenates L-3(3S)-hydroxyacyl-CoAs and their enoyl-CoAs are then converted to the corresponding 3-oxoacyl-CoAs by long-chain-enoyl-CoA hydratase(EC 4.2.1.74), which forms and dehydrogenates D-3(3R)-hydroxyacyl-CoAs.

It is involved in bile acid synthesis and is the second-to-last component in the synthesis of chenodeoxyglycocholate. 3a,7a-dihydroxy-5b-24-oxocholestanoyl-CoA is synthesized from 3a,7a,24-trihydroxy-5b-cholestanoyl-CoA and then transformed via acetyl-coA acyltransferase to chenodeoxyglycocholoyl-CoA and then finally to chenodeoxyglycocholate. Chenodeoxyglycocholate is a glycine conjugated bile acid. Bile acids are steroid acids found predominantly in bile of mammals. The distinction between different bile acids is minute, depends only on presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g., membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues.

3-Oxopimelyl-CoA
3-Oxopimelyl-CoA is an intermediate in benzoyl-CoA degradation II (anaerobic) and can be generated from the enzymatic oxidation of 3-hydroxypimelyl-CoA via the enzyme 3-hydroxypimeloyl-CoA dehydrogenase(EC 1.1.1.259). Biodegradation of aromatic compounds is a common process in anoxic environments. The many natural and synthetic aromatic compounds found in the environment are usually degraded by anaerobic microorganisms into only few central intermediates, prior to ring cleavage. Benzoyl-CoA is the most important of these intermediates since a large number of compounds, including chloro-, nitro-, and aminobenzoates, aromatic hydrocarbons, and phenolic compounds, are initially converted to benzoyl-CoA prior to ring reduction and cleavage.
