Study Notes
Proteins
- Proteins are composed of monomers called amino acids.
- Hemoglobins transport oxygen (O2) to cells; antibodies play a crucial role in the immune system.
- The diverse functions of proteins, such as hemoglobins and antibodies, arise from their unique three-dimensional structures.
Lipids
- Lipids, unlike polymers, are not made of repeating monomers connected by dehydration reactions.
- Phospholipids consist of fatty acids and glycerol, essential components of cell membranes.
Carbohydrates
- Polysaccharides are formed from monomers known as sugars.
- Chitin is a carbohydrate with structural functions, contributing to the integrity of cellular structures.
DNA
- The functional properties of DNA are derived from its structural characteristics.
- DNA forms a double helix due to noncovalent bonds between bases, while the sugar-phosphate backbone interacts with water.
Energy Storage
- The human body stores energy as glycogen, a polymer of glucose.
- When energy is needed, glycogen undergoes hydrolysis to convert back to glucose.
