General chemical structure of an acyl-CoA, where R is a carboxylic acid side chain. Acyl-CoA is a group of CoA-based coenzymes that metabolize carboxylic acids. Fatty acyl-CoA's are susceptible to beta oxidation, forming, ultimately, acetyl-CoA. The acetyl-CoA enters the citric acid cycle, eventually forming several equivalents of ATP. In this ...
Yeast fatty acyl synthase, of Type I FAS, is composed of a α 6 β 6 complex in which an αβ unit forms one functional center for fatty acid synthesis. Yeast fatty acyl synthase therefore has six reaction units for its fatty acid synthesis, in which each of these units function independently from one another.
Acyl-CoAs are acyl derivatives formed via fatty acid metabolism. Acetyl-CoA, the most common derivative, serves as an acyl donor in many biosynthetic transformations. Such acyl compounds are thioesters. Names of acyl groups of amino acids are formed by replacing the -ine suffix with -yl.
When a fatty acid oxidation disorder affects the muscles, it is a metabolic myopathy. Moreover, cancer cells can display irregular fatty acid metabolism with regard to both fatty acid synthesis [44] and mitochondrial fatty acid oxidation (FAO) [45] that are involved in diverse aspects of tumorigenesis and cell growth.
Saturated fatty acids 16 and 18 carbons in length are the dominant types in the epidermis, [35] [36] while unsaturated fatty acids and saturated fatty acids of various other lengths are also present. [ 35 ] [ 36 ] The relative abundance of the different fatty acids in the epidermis is dependent on the body site the skin is covering. [ 36 ]

Fatty acid synthase is a multi-enzyme protein that catalyzes fatty acid synthesis. It is not a single enzyme but a whole enzymatic system composed of two ...
Long-chain-fatty-acid—CoA ligase catalyzes the reaction between a fatty acid with ATP to give a fatty acyl adenylate, plus inorganic pyrophosphate, which then reacts with free coenzyme A to give a fatty acyl-CoA ester and AMP. If the fatty acyl-CoA has a long chain, then the carnitine shuttle must be utilized (shown in the table below):
The fatty acid synthetase used to produce omega-alicyclic fatty acids is also used to produce membrane branched-chain fatty acids. In bacteria with membranes composed mainly of omega-alicyclic fatty acids, the supply of cyclic carboxylic acid-CoA esters is much greater than that of branched-chain primers. [ 24 ]
