Nhanganyaya

D-alanine inonzi chiral amino acid. D-alanine icrystalline solid isina ruvara inonyungudika mumvura nemaasidhi. Iyo ine acidic uye alkaline uye inoshandawo se organic acid.

Nzira yekugadzirira yeD-alanine iri nyore. Nzira yekugadzirira yakajairika inowanikwa ne enzymatic catalysis ye chiral reactions. D-alanine inogonawo kuwanikwa ne chiral isolation yealanine.

Chinhu chinokuvadza chinogona kukonzera kushatirwa kwemaziso, nzira yekufema, uye ganda. Makemikari ekuchengetedza magirazi, magurovhosi uye masks anofanirwa kupfekwa panguva yekushanda kuve nechokwadi chekuchengetedza.

Heino sumo pfupi yezvivakwa, kushandiswa, kugadzirira uye chengetedzo ruzivo rweD-alanine. Kuti uwane rumwe ruzivo rwakadzama, bvunza anoenderana nemakemikari mabhuku kana bvunza nyanzvi.

Zvakapfuura: Boc-beta-alanine (CAS# 3303-84-2)

Zvinotevera: BOC-L-2-Amino butyric acid (CAS# 34306-42-8)
