Reach

ganglioside GD1a (18:1(4E)/18:0)

362,296 routes · scope human · up to 3 steps · built 5 October 2026 · Reactions · API

Inferred

Every route here is a hypothesis drawn from reference reactions (Rhea and Human-GEM), not a finding. Currency species such as water, ATP and NAD(H) never form a step. Evidence key

Does it reach a compound?

No route from ganglioside GD1a (18:1(4E)/18:0) is recorded in the reactions loaded for scope ‘human’, within 3 steps. That does not mean the body cannot transform it — only that these two public releases record no such path.
