Description

Isoglobo pathway in its entirety from SphinGOMAP.

Solid conversion arrows are documented according to Sphingomap. Dotted conversions are hypothetical, either not occurring or undocumented (Sphingomap details all possible permutations of a pathway to the final glycolipid).

Numbers represent the sphingomap IDs, to be converted. Metabolites coloured red are not yet in LIPIDMAPS

Metabolites with a dotted box are hypothetical. These may or may not exist on the pathway to the final product as several different routes could occur.
