Q

Funções dos nucleotídeos

A

1) fornecimento de energia - ex: ATP (adenosina trifosfato)

2) mensageiro secundário - ex: AMPc (adenosina monofosfato cíclico)

3) aceptores de elétrons - ex: NAD (dinucleotídeo de nicotinamida e adenina)

4) Ligação fosfodiéster - ligação covalente que une os nucleotídeos entre um C 3’ de um e um C 5’ do outro.
