1A 4 Lipids

How many times do the lipids of same mass store energy compared to carbs ?

3

What state are fats at room temperature ?

Solid

What state are oils at room temperature ?

Liquid

What substances do fats and oils contain ?

They contain fatty acids and glycerol ( propane-1,2,3-triol )

How do the fatty acids and glycerol bond ?

Via ester bonds.

What is the chemical formula of glycerol ?

C3H8O3

What do all fatty acids have ?

1. A long hydrocarbon chain, a folded backbone of carbon atoms with hydrogen atoms attached

2. And a carboxyl group (-COOH) at one end.

How do fatty acids differ ?

1. The length of carbon chain can differ.

2. The fatty acid may be saturated or unsaturated.

How are the carbon atoms in a saturated fatty acid carbon chain joined together ?

1. Via single covalent bonds

What makes an unsaturated fatty acid an unsaturated fatty acid ?

1. It may have one or more carbon-carbon double bonds.

2. Monounsaturated fatty acids have one carbon-carbon double bond.

3. Polyunsaturated fatty acids have more than one.

When is a triglyceride made ?

1. When one glycerol is combined with 3 fatty acids.

What is esterification ?

1. Esterification is a type of condensation reaction.

2. During this condensation reaction, a carboxyl group of a fatty acid and a hydroxyl group of the glycerol bond together.

3. Producing 3(H20) molecules.

How does esterification looks like ?
