Lipids
-
Triglycerides
-
-
Each hydroxyl (OH) group in the glycerol interacts with a fatty acid, resulting in esterification and an ester bond

Structure
-
Esterification is a condensation reaction, water is formed by removing hydrogen from the glycerol OH- group and taking away the OH- group on the fatty acid, there is then an ester bond between carbon from the fatty acid and oxygen from the glycerol
The fatty acids can be saturated, monounsaturated or polyunsaturated
saturated fats have no double carbon-carbon bonds because they are saturated with hydrogen atoms, they are solid at room temparature
-
polyunsaturated fats have multiple double carbon-carbon bonds, liquid at room temparature
Lipids contain hydrogen, carbon and oxygen
Lipids are macro molecules - large, complex and build from repeating units
Phospholipids
-
Similar structure to triglycerides but there are only two fatty acids and the remaining one is replaced with a phosphate group
-
Head: negatively charged phosphate group which is hydrophilic meaning it will interact with and is attracted to water
