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

I-Aspartic acid (efushanisiwe njenge-D-AA, Asp, noma D) iyi-α-amino acid enefomula yamakhemikhali ethi HOOCCH(NH2)CH2COOH.I-carboxylate anion kanye nosawoti we-aspartic acid aziwa njenge-aspartate.I-L-isomer ye-aspartate ingenye yama-amino acid angama-22 e-proteinogenic, okungukuthi, amabhlogo wokwakha amaprotheni.Ama-codons ayo yi-GAU ne-GAC.
I-aspartic acid, kanye ne-glutamic acid, ihlukaniswa njenge-acidic amino acid ene-pKa engu-3.9, nokho, ku-peptide, i-pKa incike kakhulu endaweni yendawo.I-pKa efinyelela ku-14 ayivamile neze.I-Aspartate igcwele ku-biosynthesis.Njengawo wonke ama-amino acid, ukuba khona kwamaphrothoni e-asidi kuncike endaweni yamakhemikhali ensalela kanye ne-pH yesixazululo.
I-Aspartic acid iwuhlobo lwe-amino acid.Ama-amino acid asetshenziswa njengezakhi zokwakha amaprotheni emzimbeni.Olunye uhlobo lwe-aspartic acid, olubizwa nge-D-aspartic acid, alusetshenziselwa ukwenza amaprotheni, kodwa lusetshenziswa kweminye imisebenzi yomzimba.I-Aspartic acid iyi-α-amino acid esetshenziswa ku-biosynthesis yamaprotheni.Njengawo wonke amanye ama-amino acid, iqukethe iqembu lama-amino kanye ne-carboxylic acid.I-D-Aspartic Acid iwuhlobo lwe-alfa amino acid.Kusabalele ku-biosynthesis yendima.D I-Aspartic Acid ingenziwa nge-oxaloacetic acid ngokushintshwa.Ezitshalweni nama-microorganisms i-D-aspartic acid iyimpahla eluhlaza yezinhlobo eziningana zama-amino acid, njenge-methionine, i-threonine, isoleucine ne-lysine.
