Gangliosides

Definition

Gangliosides are a type of glycosphingolipid that are essential components of cell membranes, particularly in the nervous system. They play a critical role in cell signaling and neurodevelopment.

5 Must Know Facts For Your Next Test

1. Gangliosides are predominantly found in the outer layer of neuronal cell membranes.
2. They are involved in modulating signal transduction and neuron-to-neuron communication.
3. Certain neurological diseases, such as Tay-Sachs disease, are associated with abnormalities in ganglioside metabolism.
4. Dietary sources like dairy and certain meats can influence ganglioside levels in the body.
5. Gangliosides contribute to neuroplasticity, which is crucial for learning and memory throughout the lifespan.
