WebFeb 21, 2024 · phospholipids: the major components of cell membranes. steroids: serve as chemical messengers and have other roles. Triglycerides One type of lipid is called a triglyceride, an ester derived from glycerol combined with three fatty acid molecules. Figure 14.2. 3: Triglyceride components. WebAre phospholipids polar or nonpolar? Phospholipids can be described as amphipathic (amphi means both), because they have this dual nature (part polar and part non-polar). This characteristic causes phospholipids to self-associate into large macromolecular complexes in an aqueous (watery) environment. Are phospholipids water soluble?
