Selelekela

DL-Methionine ke amino acid e seng polar. Thepa ea eona ke phofo e tšoeu ea kristale, ha e na monko, e baba hanyane, e qhibiliha ka metsing.

 

DL-Methionine e ka lokisoa ka mekhoa e fapaneng. Mokhoa o sebelisoang haholo ke oa ho kopanya lik'hemik'hale. Ka ho khetheha, DL-methionine e ka hlahisoa ke karabelo ea acylation ea alanine e lateloang ke karabelo ea phokotso.

 

Tlhahisoleseding ea Tšireletseho: DL-Methionine e bolokehile ka tšebeliso e tloaelehileng le ho noa ka mokhoa o itekanetseng. Ho ja haholo ho ka baka litla-morao tse kang ho nyekeloa ke pelo, ho hlatsa le letšollo. E lokela ho sebelisoa ka hloko ho lihlopha tse itseng tsa batho, tse kang bakhachane, masea le bana ba banyenyane, le batho ba nang le allergy.
