Sphingolipid metabolism: integrated pathway (Homo sapiens)

From WikiPathways

Jump to: navigation, search


Description

This pathway is inspired by the [Lipidmaps>Sphingolipids pathway (all chain lengths)](https://lipidmaps.org/pathway/pathways_maps). Sphingolipids are a class of lipids, which act as signal transduction and cell recognition molecules. This pathway shows all different tail lengths and their conversions into specific products. All products are annotated with lipid-specific identifiers (if available). The general overview pathway can be found [here](https://www.wikipathways.org/index.php/Pathway:WP4344).
