Taw qhia ntawmCAS: 672-15-1|L-homoserine
Homoserine (tseem hu ua isothreonine) yog -amino acid nrog cov tshuaj formula HO2CCH(NH2)CH2CH2OH. L-Homoserine tsis yog ib qho ntawm cov amino acids uas encoded los ntawm DNA. Nws txawv ntawm cov proteinogenic amino acid serine los ntawm kev ntxig ib qho ntxiv -CH2- rau hauv cov pob txha. Homoserine, los yog nws daim ntawv lactone, yog cov khoom ntawm cyanogen bromide cleavage ntawm peptide los ntawm degradation ntawm methionine.
Homoserine yog ib qho nruab nrab hauv biosynthesis ntawm peb yam tseem ceeb amino acids: methionine, threonine (ib qho isomer ntawm homoserine), thiab isoleucine. Nws tsim los ntawm ob qhov kev txo qis ntawm aspartic acid los ntawm kev cuam tshuam ntawm aspartate semialdehyde.
