| terpene | <plant biology> Lipid species, very abundant in plants. In principle terpenes are polymers of isoprene units. Function in plants is not clear. In animals dolichol, an important carrier species in the formation of glycoproteins, is a terpenoid. Similarly, squalene, an intermediate in the synthesis of cholesterol is a terpene. (13 Jan 1998) |
