triglycerides

4 functions of triglycerides

Source of energy

Store of energy

Protect organs

Structure membranes

Structure if a triglyceride

One glycerol attached to three fatty acids

2 basic structure of a fatty acid

Carboxylic group and long chain of carbon and hydrogen atoms

Saturated fatty acids

Contain single covalent bond

Unsaturated fatty acids

At least one double covalent bond between a two carbons

monounsaturated

One double covalent bond

polyunsaturated

Two or more double covalent bonds

Structure of glycerol

Three carbon atoms with three hydroxyl groups

bond between glycerol and fatty acid chains

Ester bond

how is an ester bond formed in a triglyceride?

Condensation reaction

how us a triglyceride broken down

Lipase enzyme and water break ester bond releasing energy so a hydrolysis reaction.

why doesn't a triglyceride dissolve in water?

Non polar so hydrophobic
