Lipid compounds including: . 3.4 What Are Lipids?. Lipids. are a diverse group of molecules that contain regions composed almost entirely of hydrogen and carbon. All lipids contain large chains of nonpolar hydrocarbons. Most lipids are therefore hydrophobic and water insoluble. Learning Objectives. Learn what a triglyceride is.. Learn what a fatty acid is.. Learn the structure of a . phospholipid. .. Learn how lipids are tested for.. What is a lipid?. Like most other biochemical substances, lipids contain . Chapter 4. Objectives.

Lipids are found naturally in all living organisms.. Lipids are hydrophobic or amphipathic small molecules that may originate entirely or in part by carbanion-based condensations of thioesters (fatty acids, polyketides, etc.) and/or by carbocation-based condensations of isoprene units .
