Lithethefatsi tsa 1.Amino acid, lisebelisoa tse tala bakeng sa ho tšeloa ha amino acid le litokisetso tsa motsoako oa amino acid.
Li-reagents tsa likokoana-hloko, lithethefatsi tse ngata. Ke amino acid e sa hlokahaleng bakeng sa 'mele oa motho. Thabisa methapo, hanela khatello ea maikutlo, tsitsise maikutlo; fokotsa lebelo la pelo, laola khatello ea mali; ntlafatsa mamello ea 'mele.
Lisebelisoa tse 3 tsa phepo e nepahetseng. E sebelisoa meriana ho phekola myelitis, lefuba encephalitis, hyperthyroidism le maloetse a mang. E boetse e sebelisoa ho etsa L-dopa diiodotyrosine. Kamora ho futhumatsa le tsoekere, amino carbonyl reaction e ka hlahisa lintho tse khethehileng tsa tatso.
