Abscisic acid (ABA) is an isoprenoid plant hormone, which is synthesized in the plastidal 2-C-methyl-d-erythritol-4-phosphate (MEP) pathway; unlike the structurally related sesquiterpenes, which are formed from the mevalonic acid-derived precursor farnesyl diphosphate (FDP), the C15 backbone of ABA is formed after cleavage of C40 carotenoids in MEP. 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-ABA5-(1-Hydroxy-2,6,6-trimethyl-4-oxo-2-cyclohexen-1-yl)-3-methyl-2,4-pentadienoic acid, 9CIAbscisin IIDorminC15H20O4264.3169264.136159128(2E,4E)-5-(1-hydroxy-2,6,6-trimethyl-4-oxocyclohex-2-en-1-yl)-3-methylpenta-2,4-dienoic acidabscisic acid, (+)-7773-56-0C\C(\C=C\C1(O)C(C)=CC(=O)CC1(C)C)=C/C(O)=OInChI=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.Abscisic acids and derivativesOrganic compoundsLipids and lipid-like moleculesPrenol lipidsSesquiterpenoidsAliphatic homomonocyclic compoundsCarboxylic acidsCyclohexenonesHydrocarbon derivativesHydroxy fatty acidsMedium-chain fatty acidsMethyl-branched fatty acidsMonocarboxylic acids and derivativesOrganic oxidesTertiary alcoholsUnsaturated fatty acidsAbscisic acidAlcoholAliphatic homomonocyclic compoundBranched fatty acidCarbonyl groupCarboxylic acidCarboxylic acid derivativeCyclic ketoneCyclohexenoneFatty acidFatty acylHydrocarbon derivativeHydroxy fatty acidKetoneMedium-chain fatty acidMethyl-branched fatty acidMonocarboxylic acid or derivativesOrganic oxideOrganic oxygen compoundOrganooxygen compoundTertiary alcoholUnsaturated fatty acidabscisic acidslogp1.88logs-3.17solubility1.79e-01 g/lmelting_point161-163 °Clogp2.09pka_strongest_acidic4.74pka_strongest_basic-3.5iupac(2E,4E)-5-(1-hydroxy-2,6,6-trimethyl-4-oxocyclohex-2-en-1-yl)-3-methylpenta-2,4-dienoic acidaverage_mass264.3169mono_mass264.136159128smilesC\C(\C=C\C1(O)C(C)=CC(=O)CC1(C)C)=C/C(O)=OformulaC15H20O4inchiInChI=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+inchikeyJLIDBLDQVAYHNE-WEYXYWBQSA-Npolar_surface_area74.6refractivity74.98polarizability28.33rotatable_bond_count3acceptor_count4donor_count2physiological_charge-1formal_charge0Specdb::CMs26075Specdb::CMs44721Specdb::CMs167132Specdb::MsMs323746Specdb::MsMs323747Specdb::MsMs323748Specdb::MsMs371986Specdb::MsMs371987Specdb::MsMs371988Specdb::MsMs2751679Specdb::MsMs2751680Specdb::MsMs2751681Specdb::MsMs2930427Specdb::MsMs2930428Specdb::MsMs2930429HMDB3609322152#<Reference:0x00005556758482f0>#<Reference:0x0000555675848110>American cranberryType 1specificVaccinium macrocarpon13750AniseType 1specificPimpinella anisum2711920.02240.02240.0224mg/100 gAppleType 1specificMalus pumila283210AvocadoType 1specificPersea americana3435BarleyType 1specificHordeum vulgare4513CarawayType 1specificCarum carvi48032CarobType 1specificCeratonia siliqua20340Common beanType 1specificPhaseolus vulgaris3885Common peaType 1specificPisum sativum3888CorianderType 1specificCoriandrum sativum4047CornType 1specificZea mays4577FennelType 1specificFoeniculum vulgare48038Garden onionType 1specificAllium cepa4679Garden tomato (var.)Type 1specificSolanum lycopersicum var. lycopersicum397755Scarlet beanType 1specificPhaseolus coccineus3886Soy beanType 1specificGlycine max3847SunflowerType 1specificHelianthus annuus4232Sweet orangeType 1specificCitrus sinensis2711
