Biomolecules (biological macromolecules) - 4 types
Carbohydrates
Lipids
Proteins
Nucleic Acids
14
Carbohydrates
Functions: Stores energy and provide structural support
Carbs are broken down into simple sugars.
When the body needs energy, carbs are broken down into simple sugars that serve as an energy source
In plants, a carb provides structural support in cell walls
Made up of Carbon, Hydrogen, Oxygen (CHO)

16
Lipids
Functions: energy storage and provide barriers
Lipids are made up of fats, oils, and waxes
Plants are coated with wax to prevent water loss, and honeycomb in a beehive is made of beeswax
Made up of Carbon, Hydrogen, Oxygen (CHO)

Proteins
Functions: Builds and repairs tissues, makes hormones, speed up reactions
Our muscles, skin and hair are all made of proteins
Made up of small Carbon compounds called Amino acids
Amino acids are made of Carbon, Hydrogen, Oxygen, Nitrogen (CHON)
