      A long-chain primary fatty alcohol that is henicosane in which a hydrogen attached to one of the terminal carbons is replaced by a hydroxy group. It has been isolated from the aerial parts of <ital>Si egesbeckia orientalis</ital> and from an Italian bread wheat variety, Pegaso, and its 11 near-isogenic lines. ChEBI CHEBI:78410
