Iipropati ze-Amino Acids

iindaba1
Iimpawu ze-α-amino acids ziyinkimbinkimbi, kodwa zilula kuba yonke i-molecule ye-amino acid ibandakanya amaqela amabini asebenzayo: i-carboxyl (-COOH) kunye ne-amino (-NH2).
Imolekyuli nganye inokuqulatha ikhonkco elisecaleni okanye iqela le-R, umz.Amaqela e-R aneentlobo ngeentlobo zeemilo, ubukhulu, iintlawulo, kunye nokuphinda kusebenze.Oku kuvumela ii-amino acids ukuba zibekwe ngokwamaqela ngokweempawu zeekhemikhali zamatyathanga abo asecaleni.

Ii-amino acids ziziqina eziyikristale ezidla ngokunyibilika emanzini kwaye zinyibilika kancinane kuphela kwizinyibilikisi zendalo.I-solubility yabo ixhomekeke kubukhulu kunye nendalo yekhonkco yecala.Ii-amino acids zineendawo eziphezulu zokunyibilika, ukuya kuma-200-300°C.Ezinye iipropathi zabo ziyahluka kwi-amino acid nganye.
