Zeaxanthin is the first committed ABA precursor; a series of enzyme-catalyzed epoxidations and isomerizations, and final cleavage of the C40 carotenoid by a dioxygenation reaction yields the proximal ABA precursor, xanthoxin, which is then further oxidized to ABA. Abamine has been patented by the Japanese researchers Shigeo Yoshida and Tadao Asami, which are very reluctant to make this substance available in general, neither commercially nor for research purposes.; Abscisic acid (ABA), also known as abscisin II and dormin, is a plant hormone. It functions in many plant developmental processes, including bud dormancy. Abscisic acid is found in many foods, some of which are carob, anise, soy bean, and scarlet bean. 2-trans-ABA 5-(1-Hydroxy-2,6,6-trimethyl-4-oxo-2-cyclohexen-1-yl)-3-methyl-2,4-pentadienoic acid, 9CI Abscisin II Dormin C15H20O4 264.3169 264.136159128 (2E,4E)-5-(1-hydroxy-2,6,6-trimethyl-4-oxocyclohex-2-en-1-yl)-3-methylpenta-2,4-dienoic acid abscisic acid, (+)- 7773-56-0 C\C(\C=C\C1(O)C(C)=CC(=O)CC1(C)C)=C/C(O)=O InChI=1S/C15H20O4/c1-10(7-13(17)18)5-6-15(19)11(2)8-12(16)9-14(15,3)4/h5-8,19H,9H2,1-4H3,(H,17,18)/b6-5+,10-7+ JLIDBLDQVAYHNE-WEYXYWBQSA-N belongs to the class of organic compounds known as abscisic acids and derivatives. These are terpene compounds containing the abscisic acid moiety, which is characterized by a 3-methylpenta-2,4-dienoic acid attached to the C1 carbon of a 4-oxocyclohex-2-ene moiety.
