Isingeniso

I-D-alanine iyi-chiral amino acid. I-D-alanine iyikristale eqinile engenambala encibilika emanzini nama-asidi. Ine-asidi ne-alkaline futhi isebenza njenge-asidi ephilayo.

 

Indlela yokulungiselela i-D-alanine ilula. Indlela evamile yokulungiselela itholakala nge-enzymatic catalysis of chiral reactions. I-D-alanine ingatholakala futhi ngokuhlukaniswa kwe-chiral kwe-alanine.

Kuyinto evamile eyingozi engase ibangele ukucasuka emehlweni, umgudu wokuphefumula, nesikhumba. Izibuko zokuphepha zamakhemikhali, amagilavu ​​namamaski kufanele kugqokwe ngesikhathi sokusebenza ukuze kuqinisekiswe ukuphepha.

 

Nasi isingeniso esifushane sezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwe-D-alanine. Ukuze uthole ulwazi oluthe xaxa, thintana nezincwadi zamakhemikhali ezifanele noma thintana nochwepheshe.
