D-aspartic acid | 1783-96-6

Aspartic acid (nke akpọrọ D-AA, Asp, ma ọ bụ D) bụ α-amino acid nwere usoro kemịkalụ HOOCCH (NH2) CH2COOH. A na-akpọ carbonoxylate anion na nnu nke aspartic acid dị ka aspartate. L-isomer nke aspartate bụ otu n'ime proteinogenic amino acid 22, ya bụ, ihe mgbochi protein. codons ya bụ GAU na GAC.
Aspartic acid bụ, yana glutamic acid, nkewapụtara dị ka amino acid acid nwere pKa nke 3.9, Otú ọ dị, na peptide, pKa na-adabere na gburugburu ebe obibi. A pKa dị elu dị ka 14 abụghị ihe ọhụrụ. Aspartate na-abawanye na biosynthesis. Dị ka ọ dị na amino acid niile, ọnụnọ nke proton acid na-adabere na gburugburu kemịkalụ mpaghara nke fọdụrụ na pH nke ngwọta.
Aspartic acid bụ ụdị amino asịd. A na-eji Amino acid eme ihe dị ka ihe na-emepụta protein n'ime ahụ. A naghị eji otu ụdị aspartic acid, nke a na-akpọ D-aspartic acid, eme protein, mana a na-eji ya na ọrụ ahụ ndị ọzọ. Aspartic acid bụ α-amino acid nke a na-eji na biosynthesis nke protein. Dị ka amino acid ndị ọzọ, ọ nwere otu amino acid na carboxylic acid. D-aspartic acid bụ ụdị alfa amino acid. Ọ na-agbasa na biosynthesis nke ọrụ. D nwere ike ime aspartic acid site na oxaloacetic acid site na transamination. Maka osisi na microorganisms D-aspartic acid bụ akụrụngwa nke ọtụtụ ụdị amino acid dị ka methionine, threonine, isoleucine na lysine.
