Methylene blue, methylfolate, na methyl-B12: ogige kemịkal na ọrụ dị iche iche
Methylene blue abụghị methylfolate ma ọ bụ methyl-B12. Methylfolate bụ ụdị vitamin B9; methyl-B12 bụ methylcobalamin, ụdị vitamin B12. Ha na-ekere òkè n'otu mmeghachi omume kemịkal n'ahụ. Methylene blue bụ ihe e ji esiji agba nke a na-emepụta site na kemịkal, bụrụkwa ihe nwere mmetụta ọgwụ, nke kemịkal ya dị iche. Ọ bụghị ihe na-enye otu methyl dị ka nri na-edozi ahụ, ọ bụghịkwa ihe nnọchi anya vitamin nke ọ bụla n'ime ha.
