Bonjour,

j'ai besoin d'aide pour comprendre les exercices 21 et 22 du CC2013. Je ne comprends pas pourquoi le lipide doublement marqué est forcément un ether-phospholipide car on ne nous donne aucune information sur les coupures par des phospholipases etc seulement une migration: pour moi le lipide en question pourrait être un glycérophospholipide, un sphingolipide, un alkyl phospholipide ou bien en effet un éther-phospholipide.

21=DE

22=E
