progoitrin

progoitrin

an antithyroid substance in the seeds, and to a lesser extent the foliage, of rape and other plants in the family Brassicae. It is a glycoside which is converted to an active oxazolidone by an enzyme also resident in the plant. This substance 1,5-vinyl-2-thiooxazolidone is goitrogenic and inhibits growth.
