What are fats made up of?
1 glycerol and 3 fatty acids
Are fats hydrophobic or hydrophilic?
Hydrophobic
What are the 3 main functions of fats?
1) Energy storage
2) Protects internal organs
3) Prevents heat loss
Do saturated fats contain a double C (C=C) bond and what does it say about its characteristics?
No
It forms straight chains and is solid at room temperature
Do unsaturated fats contain a double C (C=C) bond and what does it say about its characteristics?
Yes
It forms a bend in the molecular structure and is liquid at room temperature
What are lipids made up of?
1 glycerol, 2 fatty acids and a phosphate
What part of a phospholipid is hydrophobic and what part is hydrophilic?
Fatty acid chain is hydrophobic and the phosphate group head is hydrophilic
What are steroids made up of?
