BIOL 1201 Chapter : Chapter 5 Reading Notes
Document Summary
This reaction is called a condensation reaction or dehydration reaction. contributes part of the water molecule that is lost. A hydrogen atom attaches to one monomer, and a hydroxyl group attaches to the adjacent monomer: our food is taken in as organic polymers that are too large for our cells to absorb. Within the digestive tract, various enzymes direct hydrolysis of specific polymers. An immense variety of polymers can be built from a small set of monomers: each cell has thousands of different kinds of macromolecules, these molecules vary among cells of the same individual. Sucrose is the major transport form of sugars in plants: lactose, milk sugar, is formed by joining glucose and galactose. It is the most abundant organic compound on earth: like starch, cellulose is a polymer of glucose. Concept 5. 4 proteins have many structures, resulting in a wide range of functions: proteins account for more than 50% of the dry mass of most cells.
