Common Nameprostaglandin a1
DescriptionProstaglandin A1, also known as PGA1, belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, prostaglandin A1 is considered to be an eicosanoid lipid molecule. The systematic name of this enzyme class is (13E)-(15S)-15-hydroxy-9-oxoprosta-10,13-dienoate Delta10-Delta11-isomerase. This enzyme is also called prostaglandin A isomerase. Prostaglandin A1 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. prostaglandin a1 is found in Larix sibirica. prostaglandin a1 was first documented in 1975 (PMID: 1165130). Ightleftharpoons } (13E)-(15S)-15-hydroxy-9-oxoprosta-11,13-dienoateHence, this enzyme has one substrate, (13E)-(15S)-15-hydroxy-9-oxoprosta-10,13-dienoate (Prostaglandin A1 or PGA1), and one product, (13E)-(15S)-15-hydroxy-9-oxoprosta-11,13-dienoate (Prostaglandin C1) (PMID: 8049495) (PMID: 944773) (PMID: 16626509).
