Y Nyob hauv cov nroj tsuag thiab cov kab mob, threonine yog
synthesized los ntawm aspartic acid ntawm α-aspartyl-semialdehyde thiab homoserine . Homoserine tau txais O-phosphorylation; Qhov no phosphate ester tau dhau los ua hydrolysis concomitant nrog kev hloov chaw ntawm OH pawg.
Dab tsi tshwj xeeb txog threonine?
Threonine yog lwm yam hydroxyl-muaj amino acidNws txawv ntawm serine los ntawm kev muaj methyl hloov pauv hauv qhov chaw ntawm ib qho ntawm hydrogens ntawm β carbon thiab nws txawv ntawm valine los ntawm hloov cov methyl hloov nrog ib pawg hydroxyl. Nco ntsoov tias ob qho tib si α thiab β carbons ntawm threonine yog optically active.
Threonine ua pyruvate li cas?
Threonine tuaj yeem ua rau pyruvate los ntawm nruab nrab aminoacetone. Peb carbon atoms ntawm tryptophan tuaj yeem tshwm sim hauv alanine, uas tuaj yeem hloov mus rau hauv pyruvate.
Dab tsi ua haujlwm pab pawg yog threonine?
Nws muaj ib qho α-amino pawg (uas yog nyob rau hauv protonated −NH + 3 daim ntawv nyob rau hauv cov kab mob lom), ib pawg carboxyl (uas yog nyob rau hauv deprotonated −COO- daim ntawv nyob rau hauv cov kab mob lom), thiab ib sab saw muaj ib pab pawg neeg hydroxyl, ua rau nws ib tug polar, uncharged amino acid.
Yuav ua li cas ntawm threonine?
Threonine xav tau los tsim glycine thiab serine, ob amino acids uas tsim nyog rau kev tsim cov collagen, elastin, thiab cov leeg nqaij. Threonine pab kom cov ntaub so ntswg thiab cov nqaij ntshiv thoob plaws lub cev muaj zog thiab elastic, suav nrog lub plawv, qhov twg nws pom muaj ntau npaum li cas.
