Isingeniso

I-DL-Methionine iyi-amino acid engeyona i-polar. Izakhiwo zayo ziyi-white crystalline powder, ayinaphunga, iyababa kancane, inyibilika emanzini.

 

I-DL-Methionine ingalungiswa ngezindlela ezahlukahlukene. Indlela esetshenziswa kakhulu yi-chemical synthesis. Ngokuqondile, i-DL-methionine ingakhiqizwa ukusabela kwe-acylation ye-alanine kulandelwa ukusabela kokunciphisa.

 

Ulwazi Lokuphepha: I-DL-Methionine iphephile ngokusetshenziswa okuvamile kanye nokudla okusesilinganisweni. Ukudla ngokweqile kungase kubangele imiphumela ethile engemihle njengesicanucanu, ukuhlanza, nesifo sohudo. Kufanele isetshenziswe ngokuqapha emaqenjini athile abantu, njengabesifazane abakhulelwe, izinsana nabantwana abancane, kanye nabantu abane-allergies.
