Li-amino acid li sebetsa e le li-chelator tsa tlhaho, tse tlamang liminerale tsa bohlokoa joalo ka tšepe, zinki le manganese, 'me li thusa ho ts'oaroa ha tsona ka metso ea limela. Ts'ebetso ena ea chelation e thibela ho koalloa ha limatlafatsi mobung, taba e tloaelehileng le menontsha e tloaelehileng, ho netefatsa hore limela li fumana phepelo e leka-lekaneng ea limatlafatsi tse nyane. Mohlala, glycine le glutamic acid li ntlafatsa ho monya ha k'halsiamo le magnesium, tse bohlokoa bakeng sa photosynthesis le nts'etsopele ea litholoana. Ka ho eketsa katleho ea tšebeliso ea limatlafatsi (NUE), manyolo a amino acid a fokotsa tlhokahalo ea lisebelisoa tse feteletseng tsa lik'hemik'hale, ho fokotsa litšenyehelo le ho fokotsa tšilafalo ea tikoloho.
