He uaua nga ahuatanga o te waikawa α-amino, engari he ngawari i te mea ko ia ngota ngota o te waikawa amino e rua nga roopu mahi: carboxyl (-COOH) me te amino (-NH2).
Kei ia ngota ngota he mekameka taha, he roopu R ranei, hei tauira ko Alanine te tauira o te waikawa amino paerewa kei roto te roopu mekameka taha methyl.He maha nga ahua o nga roopu R, nga rahi, nga utu, me nga tauhohenga.Ma tenei ka taea te whakarōpū i nga waikawa amino i runga i nga ahuatanga matū o o ratou mekameka taha.

Ko nga waikawa Amino he totoka tioata he wairewa te wai, he iti noa te memeha i roto i nga whakarewa waro.Ko to ratou whakarewatanga ka whakawhirinaki ki te rahi me te ahua o te mekameka taha.Ko nga waikawa amino he tino teitei te rewa, tae atu ki te 200-300°C.He rereke o raatau ahuatanga mo ia waikawa amino.
