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..

For example, benzene and formamid do not want to mix and neither do hexane and ethylene glycol. The main reason for this is pr are a diverse group of compounds that are insoluble in water but soluble in organic solvents such as ethanol.. The most common types of lipid are . triglycerides. (sometimes known as true fats or neutral fats), but other important lipids include waxes, steroids and cholesterol.. Prof. Mamoun Ahram. Resources. This lecture. Lippincott’s Biochemistry, Ch. 15. What are lipids?. Lipids are heterogeneous, hydrophobic, compartmentalized in membranes, as droplets of triacylglycerol (TAG), or in lipoprotein (LP) particles or, or protein-bound. . are a large and diverse group of naturally occurring organic compounds that share some general . properties. ..
