4
Q
what are fats made of
A
-3 fatty acids and 1 glycerol
5
Q
2 types of fats

A
by glycerol in form of dehydration, aka taking out h and oh
7
Q
true or false
fats are source of energy?
A
true
8
Q
brown vs white fats
A
brown= breaks down blood sugar (glucose) and fat molecules to create heat and help maintain body temperature
white= storing energy
9
Q
waxes
A
long carbon chain
is hydrophobic- hence the LONG carbon chain
10

A
change shape under pressure
used as waterproof coating since hydrophobic
