Amino-acizii sunt combinatii organice care contin in molecula una sau mai multe grupe amino si una sau mai multe grupe carboxil. Dupa structura, amino-acizii se impart in doua mari categorii:
\n1. Alifatici: unde grupele functionale sunt legate de o catena alifatica, chiar daca in molecula exista un nucleu aromatic.
\n2. Aromatici: unde grupele functionale sunt legate de un ciclu aromatic.
\nDupa asezarea relativa a grupelor functionale se deosebesc \u03b1-amino-acizi, \u03b2-amino-acizi, \u03b3-amino-acizi, etc. Dintre amino-acizii alifatici, cei mai importanti sunt \u03b1-amino-acizi, adica acei amino-acizi care contin grupele functionale legate de acelasi atom de carbon. Se deosebesc mai multe categorii mari de \u03b1-amino-acizi alifatici:
\n1. monocarboxilici
\n2. dicarboxilici
\n3. hidroxi-amino-acizi
\n4. tioamino-acizi
\n5. diamino-acizi
\n6. amino-acizi heterociclici<\/p>\n
