Lipids 2: Phospholipids and cholesterol 0.0 / 5 ? BiologyBiological moleculesASOCR Created by: cfitzgeraldCreated on: 20-12-17 16:17 Describe the structure of a phospholipid? A glycerol with 2 fatty acids and a phosphate group. 1 of 5 What happens when a surrounded by water? As the tail is hydrophobic and the head, hydrophilic, phospholipids will form a sphere(micelle) 2 of 5 Explain the difference between a Triglyceride and a phospholipid a phospholipid has a phosphate group that replaces one of the fatty acid tails on a triglyceride. 3 of 5 How does the presence of a phosphate group affect the properties of a glyceride? It makes one end of the glyceride polar, which makes it attract water. The fatty acid end of the glyceride remains non-polar 4 of 5 What reaction occurs when a phosphoric acid molecules react with glycerol? Condensation 5 of 5
