Lipids and implications of saturated fats on health Flashcards
Biological compounds
How are Lipids similar to Carbohydrates (elements)?
They contain carbon, hydrogen and oxygen (much less than C and H)
What are Lipids soluble in?
Organic solvents such as propanone and alcohols.
What are the roles of Lipids?
- Insulation
- Energy store
- Protection (around delicate internal organs)
- Produces metabolic water
- Buoyancy
What do Lipids break down into?
Fatty acids and glycerol.
How do you know when a fatty acid is saturated or unsaturated?
Saturated fats have only single carbon-carbon bonds.
Unsaturated fats have at least one double bond.
What are ester bonds?

What is an atherosclerosis?
Fatty deposits on the inner wall of the coronary arteries.
What is hypertension?
High blood pressure.

When does LDL build up and cause harm?
