Abstract
A comparative discussion on the aggregation properties of gangliosides is presented. It is shown that, thanks to the steric packing features of gangliosides, significative considerations can be made on the primary and secondary structure of their headgroup, starting from their cooperative behaviour, supporting NMR direct observations.
Résumé
On présente une discussion comparative de propriétés d'agrégation dans l'eau des gangliosides. Ces glycolipides sont des tensioactifs dont la tête polaire, constituée de cycles de sucres, est très volumineuse et hydratée. En accord avec des données RMN, on montre que le propriétés d'agrégation des gangliosides sont assez sensibles à la structure primaire et secondaire de leur tête polaire.
