L-Aspartic Acid | 56-84-8 : kuv

Aspartic acid (abbreviated li D-AA, Asp, los yog D) yog α-amino acid nrog cov tshuaj formula HOOCCH (NH2) CH2COOH. Carboxylate anion thiab ntsev ntawm aspartic acid yog hu ua aspartate. L-isomer ntawm aspartate yog ib qho ntawm 22 proteinogenic amino acids, piv txwv li, lub tsev blocks ntawm cov proteins. Nws cov codons yog GAU thiab GAC.
Aspartic acid yog, ua ke nrog glutamic acid, cais raws li ib tug acidic amino acid nrog pKa ntawm 3.9, txawm li cas los xij, nyob rau hauv peptide, pKa yog nyob ntawm qhov chaw hauv cheeb tsam. Ib pKa siab li 14 tsis yog qhov tsis tshua muaj. Aspartate yog pervasive hauv biosynthesis. Raws li nrog rau tag nrho cov amino acids, muaj cov kua qaub protons nyob ntawm qhov seem ntawm cov tshuaj lom neeg hauv zos thiab pH ntawm cov tshuaj.
l-arginine l-aspartate yog ib qho ntawm 20 amino acids uas tsim cov protein. l-arginine l-aspartate yog ib qho ntawm cov amino acids tsis tseem ceeb, lub ntsiab lus nws tuaj yeem ua ke hauv lub cev.
l-arginine l-aspartate yog ib qho ua ntej ntawm nitric oxide thiab lwm yam metabolites. Nws yog ib qho tseem ceeb ntawm collagen, enzymes, daim tawv nqaij thiab cov ntaub so ntswg. l-arginine l-aspartate plays lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm ntau cov protein molecules; creatine yog qhov yooj yim tshaj plaws lees paub. Nws tuaj yeem muaj cov cuab yeej antioxidant thiab txo cov khoom sib xyaw xws li ammonia thiab plasma lactate, los ntawm cov khoom ntawm kev tawm dag zog lub cev. Nws kuj tseem inhibits platelet aggregation thiab kuj tau paub tias txo cov ntshav siab.
