Selelekela

L-Tryptophan ke chiral amino acid e nang le lesale la indole le sehlopha sa amino sebopeho sa eona. Hangata ke phofo e tšoeu kapa e mosehla ea kristale e qhibilihang hanyenyane metsing 'me e eketsehile ho qhibiliha tlas'a maemo a asiti. L-tryptophan ke e 'ngoe ea li-amino acid tsa bohlokoa tse ke keng tsa etsoa ke' mele oa motho, ke karolo ea liprotheine, hape ke thepa e tala ea bohlokoa ka ho hlaka le metabolism ea liprotheine.

 

Ho na le mekhoa e 'meli ea mantlha ea ho lokisa L-tryptophan. E ’ngoe e ntšoa mehloling ea tlhaho, e kang masapo a liphoofolo, lihlahisoa tsa lebese le lipeō tsa limela. E 'ngoe e entsoe ka mekhoa ea biochemical synthesis, ho sebelisoa likokoana-hloko kapa theknoloji ea boenjiniere ba liphatsa tsa lefutso bakeng sa ho kopanya.

 

L-tryptophan ka kakaretso e bolokehile, empa ho noa haholo ho ka ba le litlamorao tse ling. Ho ja ho feta tekano ho ka baka ho ferekana ka mpeng, ho nyekeloa ke pelo, ho hlatsa le mathata a mang a tšilo ea lijo. Bakeng sa bakuli ba bang, joalo ka ba nang le tryptophan ea lefutso e sa tloaelehang lefung, ho kenngoa ha L-tryptophan ho ka baka mathata a tebileng a bophelo bo botle.
