| what are triglycerides? | they are a type of lipid |
| what does polar mean? | molecules with have dipoles |
| what does non - polar mean? | molecules which do not have dipoles |
| what does lipids contain | C,H and O |
| what is the structure of a lipid / triglycerides? | 1 glycerol and 3 fatty acid chains |
| what in the fatty acid binds with the glycerol to form the ester bond. | the OH in the carboxyl group at the end of the hydrocarbon chain |
| what does esterification mean? | the formation of an ester bond between the hydroxyl group of the glycerol binds with the carboxyl group of the fatty acids. an example of condenstion reaction |
| what does the formation of one trigylceride release. | 3 water molecles due to the 3 ester bonds |
| explain these specific ester bonds. | So, the H2O is released so the H from glycerol and the OH from the 3 fatty acids are taken out / removed so the O from the glycerol is the only that stays and the O=c- stays and bonds to an ester linkage |
| 4 function of triglycerides | insulation, protection, buoyancy and energy storage |
| how does it do insulation | as part of the myelin sheath and as adipose tissue below the skin |
| how does it peform proteciton | adipose tissue protects organs from mechanical damage |
| how does it perform buoyancy | fat/adipose tissue is low density allowing animals to float |
| how does it perform energy storage | when oxidized, a lot of energy is released. Stored in large amounts. |
