2 fatty acids chains attached to a glycerol molecule

Question 20

Structure of waxes

Answer 20

Fatty acid chain

Question 21

Saturated fat (propites)

Answer 21

Straight chains ( so sit straight in the bloodstream and clog )
High melting point
Single bonds

Question 22

Unsaturated fat

Answer 22

Double bond
Low melting point
Easier to digest
Bent shape don’t clog arteries as much

Question 23
