Cell Biology

The four classes of biological macromolecules

Carbohydrates, lipids, proteins, and nucleic acids. All except most lipids are polymers built from repeating monomer sub

Dehydration synthesis vs. hydrolysis

Dehydration synthesis (condensation) links monomers into polymers by removing a water molecule; hydrolysis breaks polyme

Monosaccharides

The simplest carbohydrates and the monomers of larger carbohydrates. Glucose, fructose, and galactose are examples, all

Functions of lipids

Lipids store energy (fats and oils), form membranes (phospholipids), provide insulation, and act as signaling molecules

Saturated vs. unsaturated fatty acids

Saturated fatty acids have no carbon-carbon double bonds and pack tightly (solid at room temperature); unsaturated fatty
