Protein
Carbohydrate
Fat

4. Carbohydrates - Sugars
Made up of carbon (carbo-), hydrogen, and oxygen (-hydrate)
Monosaccharides – simplest sugars
Polysaccharides – made from monosaccharides

5. Carbohydrates - Starches
Made up of carbon (carbo-), hydrogen, and oxygen (-hydrate)
Consists of lots of glucose molecules joined together
Produced by most green plants as an energy storage
Amylose
Amylopectin

6. Consists of a sugar alcohol (glycerol) and three fatty acids
Fats - Triglycerides
Ester
Consists of a sugar alcohol (glycerol) and three fatty acids
There can be saturated and non-saturated fats

7. Chain of amino acids covalently linked
Proteins
Chain of amino acids covalently linked
Amine group (-NH2)
Carboxylic acid (-COOH)

8. Amino acids bond together by peptide bonds
Proteins
Amino acids bond together by peptide bonds
Peptide bonds are seen between the carbon atom and the nitrogen atom
