What does this have to do with lipids? How does the hump help the camel survive? What is the related biochemical reaction?

Introduction to lipids o Lipids contain the elements carbon, hydrogen and oxygen. o They have numerous functions, primarily energy stores in animals and plants. o Lipids consist of two types of molecules - glycerol & fatty acids.

Glycerol o A molecule of glycerol is made up of three carbon atoms. o Each of these has a hydroxyl group attached to it. o Hydrogen atoms occupy the remaining positions.

Fatty Acids

A single fatty acid molecule contains an acid (COOH) group attached to a hydrocarbon chain. Hydrocarbon usually denoted by the letter ’R’. Saturated = If every carbon atom in the chain is joined by a single C-C bond. Unsaturated = at least one C=C bond. Polyunsaturated = many double bonds. Most animal fats are saturated while most plant fats are unsaturated.

Triglycerides

o A triglyceride molecule is made of a glycerol molecule and three fatty acids. o The molecules join together through the process of condensation losing a molecule of water each time a link is made. o The link between the glycerol molecule & each fatty acid is an ‘Ester Link’. o The fatty acids in a lipid molecule can differ in length and can be saturated or unsaturated.

Triglycerides

Condensation

Phospholipids o In phospholipids one of the fatty acids of a triglyceride is substituted by a phosphate group.

Phospholipids

Formation of a phospholipid

Lipids & water o Triglycerides and phospholipids have hydrophobic and hydrophilic groups. oWhat does this mean? oTo what use is this feature put in biology? oWhat happens when you mix oil in water? Describe and explain.

Cholesterol

Steroids e.g. testosterone
