I-D-Aspartic Acid | 1783-96-6

I-Aspartic acid (efinyeziweyo njenge-D-AA, i-Asp, okanye i-D) i-α-amino acid ene-chemical formula HOOCCH (NH2) CH2COOH. I-carboxylate anion kunye neetyuwa ze-aspartic acid zaziwa njenge-aspartate. I-L-isomer ye-aspartate yenye ye-22 proteinogenic amino acids, oko kukuthi, iibhloko zokwakha iiprotheni. Iikhowudi zayo yi-GAU kunye ne-GAC.
I-Aspartic acid, kunye ne-glutamic acid, ihlelwa njenge-acidic amino acid ene-pKa ye-3.9, nangona kunjalo, kwi-peptide, i-pKa ixhomekeke kakhulu kwindawo yendawo. I-pKa ukuya kutsho kwi-14 ayiqhelekanga kwaphela. I-aspartate ixhaphake kakhulu kwi-biosynthesis. Njengazo zonke ii-amino acids, ubukho beeproton ze-asidi buxhomekeke kwindawo yentsalela yekhemikhali yendawo kunye ne-pH yesisombululo.
Aspartic acid luhlobo lwe amino acid. Ii-amino acids zisetyenziswa njengeebhloko zokwakha ukwenza iprotein emzimbeni. Olunye uhlobo lwe-aspartic acid, ebizwa ngokuba yi-D-aspartic acid, ayisetyenziselwa ukwenza iprotheni, kodwa isetyenziselwa eminye imisebenzi yomzimba. I-Aspartic acid yi-α-amino acid esetyenziswa kwi-biosynthesis yeeprotheni. Njengazo zonke ezinye ii-amino acids, iqulethe iqela le-amino kunye ne-carboxylic acid. I-D-Aspartic Acid luhlobo lwe-alfa amino acid. Ixhaphakile kwi-biosynthesis yendima. D I-Aspartic Acid inokwenziwa nge-oxaloacetic acid ngokugqithiswa. Kwizityalo kunye ne-microorganisms i-D-aspartic acid yimathiriyeli ekrwada yeentlobo ezininzi ze-amino acid, njenge-methionine, i-threonine, i-isoleucine kunye ne-lysine.
