Carbohydrates
Carbohydrates
A type of organic molecule that serves as an easily accessible energy source for the body. They are composed of carbon, hydrogen, and oxygen in a ratio of approximately 1:2:1.
Monosaccharide
Monosaccharide
The simplest form of carbohydrate. It is a single chain or ring structure, with the most important ones being pentose (5 carbons) and hexose (6 carbons).
Disaccharide
Disaccharide
A carbohydrate formed when two monosaccharides are joined together through a process called dehydration synthesis.

Study Notes
Organic Molecules
- Organic molecules are the molecules of life.
- Carbohydrates are a readily available energy source for the body.
- Their general structure is Carbon : 2 * Hydrogen : Oxygen.
- Monosaccharides are single-chain or single-ring structures.
- Pentose (5 carbon) and hexose (6 carbon) sugars are crucial for the body.
- Disaccharides form when two monosaccharides join through dehydration synthesis.
- Polysaccharides are large, insoluble molecules, ideal for storage.
- Starch is the storage carbohydrate formed by plants.
- Glycogen is the storage carbohydrate of animal tissues.
Lipids
- Lipids insulate body organs, create cell membranes, and provide stored energy.
- Triglycerides are neutral molecules consisting of one glycerol and three fatty acids, serving as an energy storage molecule.
- They are primarily found beneath the skin.
- Phospholipids are modified triglycerides, having two fatty acid chains with a phosphorus-containing group, the primary component in cell membrane structure.
- Steroids are flat molecules composed of four interconnected hydrocarbon rings.
