D-Aspartic Acid | 1783-96-6

Aspartic acid (ti a kukuru bi D-AA, Asp, tabi D) jẹ α-amino acid pẹlu agbekalẹ kemikali HOOCCH (NH2) CH2COOH. Anion carboxylate ati iyọ ti aspartic acid ni a mọ ni aspartate. L-isomer ti aspartate jẹ ọkan ninu awọn amino acids proteinogenic 22, ie, awọn bulọọki ile ti awọn ọlọjẹ. Awọn codons rẹ jẹ GAU ati GAC.
Aspartic acid jẹ, papọ pẹlu glutamic acid, ti a pin si bi amino acid ekikan pẹlu pKa ti 3.9, sibẹsibẹ, ninu peptide kan, pKa gbarale pupọ si agbegbe agbegbe. pKa ti o ga bi 14 kii ṣe loorekoore rara. Aspartate jẹ ibigbogbo ni biosynthesis. Gẹgẹbi pẹlu gbogbo awọn amino acids, wiwa awọn protons acid da lori agbegbe kemikali agbegbe ti o ku ati pH ti ojutu naa.
Aspartic acid jẹ iru amino acid. A lo awọn amino acids bi awọn bulọọki ile lati ṣe amuaradagba ninu ara. Iru aspartic acid kan, ti a npe ni D-aspartic acid, ko lo lati ṣe amuaradagba, ṣugbọn o nlo ni awọn iṣẹ ara miiran. Aspartic acid jẹ α-amino acid ti o lo ninu biosynthesis ti awọn ọlọjẹ. Bii gbogbo awọn amino acids miiran, o ni ẹgbẹ amino kan ati acid carboxylic kan. D-Aspartic Acid jẹ iru alfa amino acid. O ti wa ni ibigbogbo ni biosynthesis ti ipa. D Aspartic Acid le ṣee ṣe lati oxaloacetic acid nipasẹ transamination. Fun awọn ohun ọgbin ati awọn microorganisms D-aspartic acid jẹ ohun elo aise ti ọpọlọpọ awọn iru amino acids, bii methionine, threonine, isoleucine ati lysine.
