Phospholipide amphiphile
WebUn phospholipide est un lipide contenant un groupe acide phosphorique en tant que mono ou di-ester. Cette famille inclut notamment les acides phosphatidiques et les phosphoglycérides [1]. Ce sont des lipides amphiphiles, c'est-à-dire constitués d'une « tête » polaire et de deux « queues » aliphatiques (hydrophobes). La plupart ...
