What is the chemical formula for ethanol?

C2H5OH.

p.8
Saturated vs Unsaturated Fatty Acids

What is a key feature of unsaturated fatty acids?

What replaces the third fatty acid in phospholipids?

A phosphate group.

p.10
Saturated vs Unsaturated Fatty Acids

What does it mean if a fat or oil is described as unsaturated?

It means that not all the bonds are filled up with hydrogen.

p.11
Saturated vs Unsaturated Fatty Acids

What does 'Mono' refer to in terms of bonds?

One double bond.

p.1

Phospholipids and Cell Membranes

What is similar to a triglyceride but has one fatty acid replaced by a phosphate group?

Phospholipid.

p.12
Energy Storage in Lipids

What is a key energy characteristic of fats?

Fats provide 2 times the energy of carbohydrates due to their numerous bonds.

p.14
Phospholipids and Cell Membranes

What are the main components of cell membranes?

Phospholipids.

p.3
Saturated vs Unsaturated Fatty Acids

What does it mean if a fat is described as unsaturated?
