Fatty-acyl-CoA synthase, or more commonly known as yeast fatty acid synthase (and not to be confused with long chain fatty acyl-CoA synthetase), is an enzyme complex responsible for fatty acid biosynthesis, and is of Type I Fatty Acid Synthesis (FAS). Yeast fatty acid synthase plays a pivotal role in fatty acid synthesis.
In biochemistry, fatty acid synthesis is the creation of fatty acids from acetyl-CoA and NADPH through the action of enzymes called fatty acid synthases. This process takes place in the cytoplasm of the cell. Most of the acetyl-CoA which is converted into fatty acids is derived from carbohydrates via the glycolytic pathway.
Acetyl-CoA synthetase (ACS) or Acetate—CoA ligase is an enzyme (EC 6.2.1.1) involved in metabolism of acetate. It is in the ligase class of enzymes, meaning that it catalyzes the formation of a new chemical bond between two large molecules.

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 ...
The latter conversion is mediated by acyl-CoA synthase" acyl-P + HS-CoA → acyl-S-CoA + P i + H + Three types of acyl-CoA synthases are employed, depending on the chain length of the fatty acid. [3] For example, the substrates for medium chain acyl-CoA synthase are 4-11 carbon fatty acids. [4] The enzyme acyl-CoA thioesterase takes of the acyl ...
The long chain fatty acyl-CoA ligase (or synthetase) is an enzyme (EC 6.2.1.3) of the ligase family that activates the oxidation of complex fatty acids. [2] Long chain fatty acyl-CoA synthetase catalyzes the formation of fatty acyl-CoA by a two-step process proceeding through an adenylated intermediate. [3]
In biochemistry and metabolism, beta oxidation (also β-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. Acetyl-CoA enters the citric acid cycle, generating NADH and FADH 2, which are electron carriers used in the ...
Fatty acid synthesis starts with acetyl-CoA and builds up by the addition of two-carbon units. Fatty acid synthesis occurs in the cytoplasm of cells while oxidative degradation occurs in the mitochondria. Many of the enzymes for the fatty acid synthesis are organized into a multienzyme complex called fatty acid synthase. [5]
