D-Aspartic Acid | 1783-96-6

Aspartic acid (yofupikitsidwa ngati D-AA, Asp, kapena D) ndi α-amino acid yokhala ndi mankhwala a HOOCCH(NH2)CH2COOH. Carboxylate anion ndi mchere wa aspartic acid amadziwika kuti aspartate. L-isomer ya aspartate ndi imodzi mwa 22 proteinogenic amino acid, mwachitsanzo, zomanga zamapuloteni. Ma codons ake ndi GAU ndi GAC.
Aspartic acid ndi, pamodzi ndi glutamic acid, yomwe imatchedwa acidic amino acid yokhala ndi pKa ya 3.9, komabe, mu peptide, pKa imadalira kwambiri chilengedwe. PKa yokwera mpaka 14 si yachilendo konse. Aspartate imapezeka mu biosynthesis. Mofanana ndi ma amino acid onse, kukhalapo kwa ma protoni a asidi kumadalira malo okhala ndi mankhwala am'deralo komanso pH ya yankho.
Aspartic acid ndi mtundu wa amino acid. Ma amino acid amagwiritsidwa ntchito ngati zomangira kupanga mapuloteni m'thupi. Mtundu umodzi wa aspartic acid, wotchedwa D-aspartic acid, sugwiritsidwa ntchito popanga mapuloteni, koma umagwiritsidwa ntchito m'ntchito zina za thupi. Aspartic acid ndi α-amino acid yomwe imagwiritsidwa ntchito mu biosynthesis ya mapuloteni. Monga ma amino acid ena onse, ili ndi gulu la amino ndi carboxylic acid. D-Aspartic Acid ndi mtundu wa alfa amino acid. Imafalikira mu biosynthesis ya gawo. D Aspartic Acid imatha kupangidwa kuchokera ku oxaloacetic acid ndi transamination. Kwa zomera ndi tizilombo D-aspartic asidi ndi zopangira mitundu ingapo ya amino zidulo, monga methionine, threonine, isoleucine ndi lysine.
