cis,cis-11,14-Eicosadienoyl-CoA
This compound belongs to the family of Acyl CoAs. These are organic compounds contaning a coenzyme A substructure linked to another moeity through an ester bond.
8Z,11Z-eicosadienoyl-CoA
8Z,11Z-eicosadienoyl-CoA is classified as a member of the Long-chain fatty acyl CoAs. Long-chain fatty acyl CoAs are acyl CoAs where the group acylated to the coenzyme A moiety is a long aliphatic chain of 13 to 21 carbon atoms. 8Z,11Z-eicosadienoyl-CoA is considered to be practically insoluble (in water) and acidic. 8Z,11Z-eicosadienoyl-CoA is a fatty ester lipid molecule

(8Z,11Z)-icosa-8,11-dienoyl-CoA
(8z,11z)-icosa-8,11-dienoyl-coa is an acyl-CoA or acyl-coenzyme A. More specifically, it is a (8Z_11Z)-icosa-8_11-dienoic acid thioester of coenzyme A. (8z,11z)-icosa-8,11-dienoyl-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. (8z,11z)-icosa-8,11-dienoyl-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. (8z,11z)-icosa-8,11-dienoyl-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, (8Z,11Z)-icosa-8,11-dienoyl-CoA is transported into the mitochondria, the locus of beta oxidation. Transport of (8Z,11Z)-icosa-8,11-dienoyl-CoA into the mitochondria requires carnitine palmitoyltransferase 1 (CPT1), which converts (8Z,11Z)-icosa-8,11-dienoyl-CoA into (8Z_11Z)-icosa-8_11-dienoylcarnitine, which gets transported into the mitochondrial matrix. Once in the matrix, (8Z_11Z)-icosa-8_11-dienoylcarnitine is converted back to (8Z,11Z)-icosa-8,11-dienoyl-CoA by CPT2, whereupon beta-oxidation can begin. Beta oxidation of (8Z,11Z)-icosa-8,11-dienoyl-CoA occurs in four steps. First, since (8Z,11Z)-icosa-8,11-dienoyl-CoA is a long chain acyl-CoA it is the substrate for a long chain acyl-CoA dehydrogenase, which catalyzes dehydrogenation of (8Z,11Z)-icosa-8,11-dienoyl-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 ...
