Biological molecules- lipids

Question 1

What are the 2 types of Lipids?

Answer 1

Triglycerides (fat for energy store, insulation, protection of organs)
 Phospholipids (to make membranes)

Question 2

Structure of triglyceride?

Answer 2

 made of 1 glycerol and 3 fatty acids
 joined by condensation reaction, ester bonds
 bond is COOC
 there are 2 types of triglycerides: saturated fat and unsaturated fat

Question 3

Saturated Fat

Answer 3

has no carbon double bonds in the R group of the fatty acid

Question 4

Unsaturated Fat

Answer 4

has carbon double bonds in the R group of the fatty acid

Question 5

Structure of phospholipid

Answer 5

 made of 1 glycerol, 2 fatty acids and 1 phosphate
 phosphate forms a hydrophillic head, fatty acids form hydrophobic tails
 forms a phospholipid bilayer, basic structure of membranes
