Functions of Carbohydrates

Four Groups of Organic Compounds

Carbohydrates:
- Elements: Carbon, Hydrogen, Oxygen
- Food sources: Sugars, starches, fiber (glucose, sucrose, fructose)
- Found in: Plants, fruits, grains, vegetables
- Functions: First source of energy, building blocks, cell structure.
Lipids:
- Elements: Carbon, Hydrogen, Oxygen
- Food sources: Fats, oils, avocado, nuts, eggs, cheese, milk.
- Functions: Energy storage (second source), insulation, cell membranes, hormones.
Proteins:
- Elements: Carbon, Hydrogen, Oxygen, Nitrogen
- Food sources: Meat, eggs, milk, fish, beans, nuts.
- Functions: Build and repair tissues, enzymes, hormones, antibodies.
Nucleic Acids:
- Elements: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus
- Food sources: High protein foods, body milk
- Functions: Carry genetic information (DNA, RNA), protein synthesis.

Uses of Compounds in the Body and Cells

Carbohydrates: Short-term energy, source of creating ATP. Components of cell walls.
Lipids: Long-term energy storage, major component of cell membranes.
Proteins: Build body tissues, enzymes, hormones, antibodies.
Nucleic Acids: Carry genetic information, essential for protein production.
