MONOENOIC FATTY ACIDS In his classic studies on fatty acids from pork fat, Chevreul (1823) recognized the nature of oleic acid but it […]
DITERPENES They have 20 carbon atoms and are derived from geranylgeraniol pyrophosphate. They are of fungal or plant origin and are found […]
POLYENOIC FATTY ACIDS These fatty acids (also called polyunsaturated fatty acids, PUFA) have 2 or more cis double bonds which are the […]
TERPENOIDS INTRODUCTION Terpenoids (or isoprenoids), a subclass of the prenyllipids (terpenes, prenylquinones, and sterols), represent the oldest group of small molecular products […]
MONOACYLGLYCEROLS These lipids (known also as monoglycerides) are fatty acid monoesters of glycerol and thus, due to the orientation of that molecule, two […]
DIACYLGLYCEROLS These lipids (known also as diglycerides) are fatty acid diesters of glycerol and occur in two isomeric forms: R and R’ are […]
