D-Aspartic Acid | 1783-96-6

Aspartic acid (e khutsufalitsoeng e le D-AA, Asp, kapa D) ke α-amino acid e nang le foromo ea lik'hemik'hale HOOCCH(NH2)CH2COOH. Carboxylate anion le letsoai la aspartic acid li tsejoa e le aspartate. L-isomer ea aspartate ke e 'ngoe ea li-amino acid tse 22 tsa proteinogenic, ke hore, li-block tsa liprotheine. Li-codon tsa eona ke GAU le GAC.
Aspartic acid e, hammoho le glutamic acid, e khetholloa e le acidic amino acid e nang le pKa ea 3.9, leha ho le joalo, ka peptide, pKa e itšetlehile haholo ka tikoloho ea sebaka seo. PKa e phahameng joalo ka 14 ha se ntho e sa tloaelehang ho hang. Aspartate e atile haholo ho biosynthesis. Joalo ka li-amino acid tsohle, boteng ba liprothone tsa asiti bo ipapisitse le tikoloho ea sebaka sa masala ea lik'hemik'hale le pH ea tharollo.
Aspartic acid ke mofuta oa amino acid. Li-amino acid li sebelisoa e le lithupa ho etsa protheine 'meleng. Mofuta o mong oa asiti ea aspartic, e bitsoang D-aspartic acid, ha e sebelisoe ho etsa protheine, empa e sebelisoa mesebetsing e meng ea 'mele. Aspartic acid ke α-amino acid e sebelisoang ho biosynthesis ea liprotheine. Joalo ka li-amino acid tse ling kaofela, e na le sehlopha sa amino le asiti ea carboxylic. D-Aspartic Acid ke mofuta oa alfa amino acid. E atile ho biosynthesis ea karolo. D Aspartic Acid e ka etsoa ka oxaloacetic acid ka transamination. Bakeng sa limela le likokoana-hloko D-aspartic acid ke thepa e tala ea mefuta e mengata ea amino acid, joalo ka methionine, threonine, isoleucine le lysine.
