الشَحميات السِّفنغولية السكرية أو الشحميات السفنجولية السكرية (بالإنجليزية: Glycosphingolipid) هي أحد الأنواع الفِرعية من التي تحتوي الكحول الأميني سفينغوزين، ومن المُمكن أن تُعتبر شحميات سفينغولية مُرتبطة مع مجموعة سكريات، تتضمن هذه الشحميات: * السيريبروزيد. * الغانغليوزيد. * الغلوبوزيد. (ar) Als Glycosphingolipide (GSL) bezeichnet man eine Gruppe von Lipiden (genauer gesagt von Sphingolipiden), die am Aufbau von Zellmembranen beteiligt sind. Sie enthalten einen hydrophoben Ceramid-Anteil und einen glycosidisch gebundenen Kohlenhydratanteil. Dieser Oligosaccharid-Anteil wird auf der Außenseite der Zellmembran präsentiert, wo er für biologische Prozesse wie Zell-Adhäsion oder Zell-Zell-Interaktionen von Bedeutung ist. Auch bei der Onkogenese sowie der Ontogenese sind Glycosphingolipide von Bedeutung. (de) Glycosphingolipids are a subtype of glycolipids containing the amino alcohol sphingosine. They may be considered as sphingolipids with an attached carbohydrate. Glycosphingolipids are a group of lipids (more specifically, sphingolipids) and are a part of the cell membrane. They consist of a hydrophobic ceramide part and a glycosidically bound carbohydrate part. This oligosaccharide content remains on the outside of the cell membrane where it is important for biological processes such as cell adhesion or cell–cell interactions. Glycosphingolipids play also important role in oncogenesis and ontogenesis. (en) La sphingosine est liée à une chaîne glucidique dont l'enchaînement des oses code une information. Les glycosphingolipides se retrouvent donc sur certaines membranes plasmiques spécialisées. * Portail de la chimie * Portail de la biochimie (fr) 당스핑고지질(영어: glycosphingolipid)은 인 스핑고신을 함유하고 있는 당지질의 한 종류이다. 당스핑고지질은 탄수화물이 부착된 스핑고지질로 간주될 수 있다. 당스핑고지질은 지질(보다 구체적으로 스핑고지질)의 한 부류이며, 세포막의 일부이다. 당스핑고지질은 소수성인 세라마이드 부분과 글리코사이드 결합으로 결합된 탄수화물 부분으로 구성되어 있다. 이러한 탄수화물 부분은 세포막의 외부에서 세포 부착이나 세포-세포 상호작용과 같은 생물학적 과정에서 중요한 역할을 한다. 당스핑고지질은 또한 종양발생 및 개체발생에서 중요한 역할을 한다.
