D-Aspartic Acid |1783-96-6 : kuv
Khoom Description
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 ib puag ncig.Ib pKa siab li 14 tsis yog qhov tsis tshua muaj.Aspartate yog pervasive hauv biosynthesis.Raws li nrog tag nrho cov amino acids, lub xub ntiag ntawm cov kua qaub protons nyob ntawm qhov seem ntawm cov tshuaj lom neeg hauv zos thiab pH ntawm cov tshuaj.
Aspartic acid yog ib hom amino acid.Amino acids yog siv los ua cov khoom tsim los ua cov protein hauv lub cev.Ib hom aspartic acid, hu ua D-aspartic acid, tsis yog siv los ua cov protein, tab sis nws yog siv rau lwm lub cev ua haujlwm.Aspartic acid yog α-amino acid uas siv rau hauv biosynthesis ntawm cov protein.Zoo li tag nrho lwm cov amino acids, nws muaj ib pawg amino thiab carboxylic acid.D-Aspartic Acid yog ib hom alfa amino acid.Nws yog dav hauv biosynthesis ntawm lub luag haujlwm.D Aspartic Acid tuaj yeem tsim los ntawm oxaloacetic acid los ntawm kev hloov pauv.Rau cov nroj tsuag thiab microorganisms D-aspartic acid yog raw khoom ntawm ntau hom amino acids, xws li methionine, threonine, isoleucine thiab lysine.
Function & Application
zaub mov thiab tshuaj lom neeg kev lag luam.
Hauv kev lag luam khoom noj khoom haus, nws yog ib qho khoom noj khoom haus zoo, ntxiv rau ntau yam dej qab zib refreshing;Nws tseem yog cov khoom siv tseem ceeb ntawm cov khoom qab zib (aspartame)-aspartame.
