Glycine yog ib qho tsis tseem ceeb amino acid rau tib neeg lub cev
Taw qhia
Glycine tag nrho yog ib qho polar molecule (tag nrho cov amino acids yog polar), tab sis nws yog ib qho tsis-polar amino acid. Qhov no yog vim qhov polarity ntawm cov amino acid yog txiav txim los ntawm qhov xwm ntawm nws pawg R, tsis yog tag nrho cov molecule.
Glycine branched saw yog ib tug hydrogen atom uas faib nws raws li ib tug hydrocarbon saw, uas tsis yog-polar. Ib yam li ntawd, txawm tias nws yooj yim soluble hauv dej, nws yog hydrophobic amino acid.
