GO:0001576 globoside biosynthetic process

The chemical reactions and pathways resulting in the formation of a ceramide with a core structure of GalNAc-beta-(1->3)-Gal-alpha-(1->4)-Glc(I).

• New superclass (parent) suggested

If this is a valid classification it should have is_a ceramide biosynthetic process, since it is defined as a ceramide

• Reference(s), if appropriate

may be a definition proble.
Glycosphingolipids are derived from ceramides

This is a ChEBI issue. Please open a ticket there.

Is globoside definitely a ceramine, though?

[deustp01]

A quick Google search shows that:

• Globosides are a type of glycosphingolipid (GSL) made up of a ceramide backbone, and a terminal oligosaccharide.
• A ceramide is composed of sphingosine and a fatty acid joined by an amide bond.
• Sphingosine (2-amino-4-trans-octadecene-1,3-diol) is an 18-carbon amino alcohol with an unsaturated hydrocarbon chain.

So a ceramide is a part of a globoside in the same way that adenine is a part of NAD.

OK, I will alter the definiton.
