(4Z,15Z)-bilirubin IXalpha

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

3 compounds within 3 steps: 2 in 1, 1 in 2, 0 in 3
