Dika amino acid di nkpa na aru mmadu, enwere ike iji L-methionine mee ihe dika ihe oriri na ihe oriri na ihe ndi ozo dika ihe ndi ozo.
Agbakwunyere na nri anumanu, L-methionine nwere ike inyere umu anumanu aka ito ngwa ngwa n'ime obere oge ma ihe 40% nke nri ha nwere ike ịchekwa.
Dịka ihe dị mkpa na njikọ protein, L-methionine nwere mmetụta nchedo na akwara obi. N'otu oge ahụ, L-methionine nwere ike gbanwee n'ime Taurine site na sọlfọ, ebe Taurine nwere mmetụta pụtara ìhè doro anya. L-methionine nwekwara ezigbo ọrụ maka nchekwa imeju na nsị, ya mere a na-ejikarị ya agwọ ọrịa nke ọrịa imeju dịka cirrhosis, imeju abụba na nnukwu ọrịa ịba ọcha n'anya na-adịghị ala ala.
