Tšebeliso

Phofo e tšoeu ea kristale
Liplatelete tse tšoeu, tse kristale kapa phofo e nang le monko o ikhethang.1 g e qhibiliha ka 30 ml ea metsi.E qhibiliha ka har'a li-acids tse hlapollang le methapong ea alkali hydroxides.E qhibiliha hanyenyane joala, 'me ha e khonehe ho ether.Ha e sebetse ka mokhoa oa optically.PH ea tharollo ea 1 ho 100 e pakeng tsa 5.6 le 6.1.Ntho ena e ka lokisoa ka ho eketsoa ha methanethiol ho acrolein;ka phetoho ea lik'hemik'hale ea methylthiopropionic aldehyde.

d,l-Methionine e na le monko o ikhethang.Ke amino acid ea bohlokoa 'me e boetse e sebelisoa e le tlatsetso ea phepo le lijo.

Tlhahiso ea metsoako e sa tsitsang e amanang le tatso ea lijo tse tsoang ho senyeha ha Strecker ea DL-methionine.Ho eketsoa ha methionine ka bongata bo loketseng lijong tsena ho ka lebelloa ho ntlafatsa boleng ba protheine.Ka moruo, DL-methionine e ka ba khetho e ntle.An nonpolar amino acid e nang le oxidative stress defense properties.DL-Methionine ka linako tse ling e fanoa e le tlatsetso ho lintja;e thusa ho boloka lintja hore li se ke tsa senya joang ka ho fokotsa pH ea urine.Methionine e lumelloa e le tlatsetso ho lijo tsa likhoho tse phelang tlas'a lenaneo la US certified organic.
