Makhalidwe a α-amino acid ndi ovuta, koma ophweka chifukwa molekyu iliyonse ya amino acid imaphatikizapo magulu awiri ogwira ntchito: carboxyl (-COOH) ndi amino (-NH2).
Molekyu iliyonse imatha kukhala ndi unyolo wam'mbali kapena gulu la R, mwachitsanzo, Alanine ndi chitsanzo cha amino acid omwe ali ndi gulu la methyl side chain.Magulu a R ali ndi mawonekedwe osiyanasiyana, kukula kwake, mtengo wake, ndi zochitikanso.Izi zimathandiza kuti ma amino acid agawidwe m'magulu molingana ndi mankhwala a maunyolo awo am'mbali.

Ma amino acid ndi zolimba za crystalline zomwe nthawi zambiri zimasungunuka m'madzi ndipo zimasungunuka pang'ono mu zosungunulira za organic.Kusungunuka kwawo kumadalira kukula ndi chikhalidwe cha unyolo wam'mbali.Ma amino acid ali ndi malo osungunuka kwambiri, mpaka 200-300 ° C.Makhalidwe awo ena amasiyanasiyana pamtundu uliwonse wa amino acid.
