Toetran'ny asidra amino

vaovao1
Ny toetran'ny asidra α-amino dia sarotra, nefa tsotra satria ny molekiola tsirairay amin'ny asidra amino dia misy vondrona roa miasa: karboksil (-COOH) sy amino (-NH2).
Ny molekiola tsirairay dia mety misy rojo anilany na vondrona R, ohatra ny Alanine dia ohatra amin'ny asidra amino mahazatra misy vondrona methyl side chain.Ny vondrona R dia manana endrika isan-karazany, habe, fiampangana ary hetsika.Izany dia mamela ny asidra amino ho vondrona araka ny toetra simika amin'ny rojo vy.

Tabilao misy fanafohezana sy fananana asidra amino mahazatra

Ny asidra amino dia solida kristaly izay matetika levona anaty rano ary tsy levona afa-tsy amin'ny solvent organika.Ny solubility azy ireo dia miankina amin'ny habeny sy ny toetran'ny rojo sisiny.Ny asidra amino dia manana teboka levona avo be, hatramin'ny 200-300 ° C.Ny fananany hafa dia miovaova ho an'ny asidra amino tsirairay.
