| Leuco-adrenochrome | Leuco-adrenochrome is an impurity of Adrenochrome, which was first isolated from the products of an enzymatic oxidation. Synonyms: (S)-1-methylindoline-3,5,6-triol. Molecular formula: C9H11NO3. Mole weight: 181.19. |  |
| leucoanthocyanidin reductase | The enzyme catalyses the synthesis of catechin, catechin-4β-ol (leucocyanidin) and the related flavan-3-ols afzelechin and gallocatechin, which are initiating monomers in the synthesis of plant polymeric proanthocyanidins or condensed tannins.

| leucocyanidin oxygenase | The enzyme requires Fe(II) and ascorbate. It is involved in the pathway by which many flowering plants make anthocyanin (glycosylated anthocyandin) flower pigments.
