Protein bụ nnukwu biomolecules, ma ọ bụ macromolecules, nke nwere otu ma ọ bụ karịa ogologo ogologo nke amino acid residues. Protein na-arụ ọrụ dịgasị iche iche n'ime ihe ndị dị ndụ, gụnyere catalysing metabolic reactions, DNA replication, na-azaghachi ihe mkpali, na-enye ihe owuwu na mkpụrụ ndụ na ihe ndị dị ndụ, ma na-ebugharị ụmụ irighiri ihe site n'otu ebe gaa ebe ọzọ. Protein dị iche na ibe ha na usoro amino acid, nke usoro nucleotide nke mkpụrụ ndụ ihe nketa ha na-ekpebi, nke na-emekarị ka protein na-agbanye n'ime usoro atọ dị iche iche nke na-ekpebi ọrụ ya. Ajụjụ: Gịnị bụ aha ọzọ maka nnukwu biomolecules?
