Chemicalsof life (Ch. 4)
-We call them chemicals of life as it is what we are made of.
-These are carbohydrates, lipids and proteins.
- There are small carbohydrates with only one sugar, called monosaccharide. This is soluble in water.
- An example of monosaccharide is glucose or fructose.
- When monosaccharide get together, a disaccharide is formed. This is soluble in water, and therefore, storages energy. An example of disaccharide is starch (plants) or glycogen (animals).
- When a long chain of many carbohydrates is formed, it is called polysaccharide. This isn’t soluble in water and it is heavy. An example is sucrose.
- Carbohydrates are the body’s main source of energy and storages it too. They contain the elements carbon, hydrogen and oxygen.
- Function; To store energy as fats.
