Macromolecules
M6: Polysaccharides and Lipids are important macromolecules in cells and organisms

Learning Objective

Polysaccharides, including cellulose and chitin and Lipids contribute to the structural components of cells and organisms
Polysaccharides, including, starch and glycogen and Lipids including, fats and oil contribute to energy reserves in cells

Macromolecules Overview
Types of Compounds Elements Contained Unit Names - Large/Small Where Found/Use
Carbohydrates C, H, O - Monosaccharides = Glucose
(polysaccharides) - Disaccharides = Sucrose
- Polysaccharides = Starch, Glycogen,
Cellulose, Chitin
Lipids C, H, O (P) - Lipids (Triglycerides) = made of Glycerol
and Fatty acids (fats and oils)
- Phospholipids = made of two Fatty acids
attached to a Glycerol, a Phosphate and
Ethanolamine
- Hormone Lipid Derivatives = Steroids and
Waxes
Proteins C, H, O, N (S) Amino acids combine (20 types) to make
polypeptides which can be either;
- Structural = Collagen
- Functional = Enzymes
Nucleic Acids C, H, O, N - DNA = Chromosomes, Genes, Nucleotides,
Nitrogen Base, Sugar and Phosphate
