EN effet, suivant le pH du milieu, l'acide aminé sera sous forme COOH ou COO-Si maintenant tu prends la sérine, l'hydrogène du OH "part difficilement". Toutefois, il y a quand même une différence de charge (meme faible) entre le O et le H et le groupement est donc polaire.

Serine Definition & Structure Britannica

WebSerine has two ionizable groups: the carboxyl group (-COOH) and the amino group (-NH2). At different pH values, these groups can be either protonated or deprotonated, leading to different forms of serine. The three possible forms of serine are: Doubly protonated serine (H3Ser+), where both the carboxyl and amino groups are protonated. http://www.biology.arizona.edu/biochemistry/problem_sets/aa/Tyrosine.html mở file pdf trong word
