Iithegi zeMveliso

I-DL-Pyroglutamic acid (CAS # 149-87-1) isingeniso
I-DL pyroglutamic acid yi-amino acid, eyaziwa ngokuba yi-DL-2-aminoglutaric acid. I-DL pyroglutamic acid ngumgubo wekristale ongenambala onyibilikayo emanzini nakwi-ethanol.

Ngokuqhelekileyo kukho iindlela ezimbini zokuvelisa i-DL pyroglutamic acid: i-chemical synthesis kunye ne-microbial fermentation. I-Chemical synthesis ifumaneka ngokuphendula iikhompawundi ezifanelekileyo, ngelixa ukuvutshelwa kwe-microbial kusebenzisa i-microorganisms ethile ukuze i-metabolize kwaye idibanise i-amino acid.

Ulwazi lokhuseleko lwe-DL pyroglutamic acid: Ithathwa njengekhompawundi ekhuselekileyo nengenabutyhefu obucacileyo. Njengekhemikhali, kufuneka igcinwe kwaye isetyenziswe phantsi kweemeko ezifanelekileyo, ukuphepha ukudibanisa nee-oxidants ezinamandla. Ngaphambi kokusebenzisa i-DL pyroglutamic acid, kufuneka iphathwe ngokweenkqubo ezichanekileyo zokusebenza kunye namanyathelo okukhusela umntu.
