FACTOID # 140: In Switzerland, the average person has to work for 102 minutes to buy a kilogram of beef - one of the longest times in the developed world. On the other hand, they only have work 14 hours to buy a refrigerator for it.

Encyclopedia > Fatty acid synthase

Fatty acids are aliphatic acids fundamental to energy production and storage, cellular structure and as intermediates in the biosynthesis of hormones and other biologically important molecules. They are synthesised by a series of decarboxylative claisen condensation reactions from Acetyl-CoA and Malonyl-CoA. Following each round of elongation the beta keto group is reduced to the fully saturated carbon chain by the action of a ketoreductase, enol reductase and dehydratase. In chemistry, especially biochemistry, a fatty acid is a carboxylic acid (or organic acid), often with a long aliphatic tail (long chains), either saturated or unsaturated. ... In chemistry, non-aromatic and non-cyclic (acyclic) organic compounds are called aliphatic. ... Norepinephrine A hormone (from Greek όρμή - to set in motion) is a chemical messenger from one cell (or group of cells) to another. ... The Claisen condensation is a carbon-carbon bond forming reaction that occurs between two esters or one ester and another carbonyl compound in the presence of a strong base, resulting in a β-keto ester or a β-diketone. ...

The growing fatty acid chain is carried as an acyl carrier protein linked substrate, and is released by the action of a thioesterase. The acyl carrier protein is an important component in both fatty acid biosynthesis and polyketide synthases, with the growing polyketide chain bound during synthesis as a thiol ester at the distal thiol of a 4-phophopantethiene moiety. ... Thioesterases are enzymes which belong to the Esterase family. ...


There are two principal classes of fatty acid synthases.

  • Type I systems utilise a single large, multifunctional polypeptide and are common to both mammals and fungi (although the structural arrangement of fungal and mamallian synthases differ).
  • Type II, or bacterial systems, use discrete, monofunctional enzymes which are used iteratively to elongate and reduce the fatty acid chain.
