Triglycerides are composed of glycerol attached to three fatty acids via dehydration synthesis. Notice that glycerol gives up a hydrogen atom, and the carboxyl groups on the fatty acids each give up a hydroxyl group.

Polysaccharides can contain a few to a thousand or more monosaccharides. Three are important to the body:

Starches are polymers of glucose. They occur in long chains called amylose or branched chains called amylopectin, both of which are…
