Palmitelaidoyl-CoA
Palmitelaidoyl-CoA is a monounsaturated fatty acid, the product of palmitoyl-CoA from a reaction catalyzed by stearoyl-CoA desaturase (EC 1.14.99.5, SCD) in the endoplasmic reticulum, an enzyme that catalyzes the delta9-cis desaturation of saturated fatty acyl-CoAs. These monounsaturated fatty acids are used as substrates for the synthesis of triglycerides, wax esters, cholesteryl esters and membrane phospholipids. The saturated to monounsaturated fatty acid ratio affects membrane phospholipid composition and alteration in this ratio has been implicated in a variety of disease states including cardiovascular disease, obesity, diabetes, neurological disease, skin disorders and cancer. Thus, the expression of SCD is of physiological importance in normal and disease states. Unsaturated fatty acids are the most abundant form of stored fat in the human body and are vital for all living organisms. In addition to their role as an energy source, they are integral constituents of cell membranes, playing a role in membrane fluidity, cell signaling, and membrane integrity. Numerous beneficial physiologic effects have been attributed to unsaturated fatty acids, including protection from obesity, diabetes, cancer, and atherosclerosis. Palmitelaidoyl-CoA has been shown to inhibit oxidative phosphorylation in human cells which has implications for long-chain fatty acid disorders.

(4R,8R,12R)-Trimethyl-2E-tridecenoyl-CoA
(4R,8R,12R)-trimethyl-2E-tridecenoyl-CoA is an acyl-CoA with (4R,8R,12R)-trimethyl-2E-tridecenoate moiety. Acyl-CoA (or formyl-CoA) is a coenzyme involved in the metabolism of fatty acids. It is a temporary compound formed when coenzyme A (CoA) attaches to the end of a long-chain fatty acid inside living cells. The compound undergoes beta oxidation, forming one or more molecules of acetyl-CoA. This, in turn, enters the citric acid cycle, eventually forming several molecules of ATP. (4R,8R,12R)-trimethyl-2E-tridecenoyl-CoA is an acy-CoA with (4R,8R,12R)-trimethyl-2E-tridecenoate moiety.
9Z-hexadecenoyl-CoA
9Z-hexadecenoyl-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. 9Z-hexadecenoyl-CoA is considered to be slightly soluble (in water) and acidic. 9Z-hexadecenoyl-CoA is a fatty ester lipid molecule
(6Z)-Hexadecenoyl-CoA
(6z)-hexadecenoyl-coa is an acyl-CoA or acyl-coenzyme A. More specifically, it is a (6Z)-hexadec-6-enoic acid thioester of coenzyme A. (6z)-hexadecenoyl-coa is an acyl-CoA with 16 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. (6z)-hexadecenoyl-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. (6z)-hexadecenoyl-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, (6Z)-Hexadecenoyl-CoA is transported into the mitochondria, the locus of beta oxidation. Transport of (6Z)-Hexadecenoyl-CoA into the mitochondria requires carnitine palmitoyltransferase 1 (CPT1), which converts (6Z)-Hexadecenoyl-CoA into (6Z)-Hexadecenoylcarnitine, which gets transported into the mitochondrial matrix. Once in the matrix, (6Z)-Hexadecenoylcarnitine is converted back to (6Z)-Hexadecenoyl-CoA by CPT2, whereupon beta-oxidation can begin. Beta oxidation of (6Z)-Hexadecenoyl-CoA occurs in four steps. First, since (6Z)-Hexadecenoyl-CoA is a long chain acyl-CoA it is the substrate for a long chain acyl-CoA dehydrogenase, which catalyzes dehydrogenation of (6Z)-Hexadecenoyl-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 keto...
