Definition

ChEBI: 5-hydroxy-4',7-dimethoxyflavanone is a dimethoxyflavanone that is naringenin in which the hydroxy groups at positions 4' and 7 are replaced by methoxy groups. It has a role as a plant metabolite. It is a member of 4'-methoxyflavanones, a dimethoxyflavanone and a monohydroxyflavanone. It is functionally related to a naringenin.
