Amino-acizi naturali<\/span><\/u><\/b><\/div>\n
\n<\/div>\n
\n<\/div>\n
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: <\/span><\/div>\n
1.      <\/span><\/span><\/span>Alifatici<\/span><\/u>: unde grupele functionale sunt legate de o catena alifatica, chiar daca in molecula exista un nucleu aromatic.<\/span><\/div>\n
2.      <\/span><\/span><\/span>Aromatici<\/span><\/u>: unde grupele functionale sunt legate de un ciclu aromatic.<\/span><\/div>\n
\n<\/div>\n
Dupa asezarea relativa a grupelor functionale se deosebesc \u03b1-amino-acizi, \u03b2-amino-acizi, \u03b3-amino-acizi, etc.<\/span> <\/span>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:<\/span><\/div>\n
1.      <\/span><\/span><\/span>monocarboxilici<\/span><\/div>\n
2.      <\/span><\/span><\/span>dicarboxilici <\/span><\/div>\n
3.      <\/span><\/span><\/span>hidroxi-amino-acizi<\/span><\/div>\n
4.      <\/span><\/span><\/span>tioamino-acizi<\/span><\/div>\n
5.      <\/span><\/span><\/span>diamino-acizi<\/span><\/div>\n
