| Question | Answer |
| ISOMERS | Compounds that have the same chemical formula, but which differ in the arrangement of atoms |
| POLYMERS | Longer chains of repeating monomer units |
| CONDENSATION REACTION | When 2 monosaccharides join to from a disaccharide with the elimination of water and the formation of a glycosidic bond |
| HYDROLYSIS | The addition of water to a disaccharide resulting in the formation of 2 monosaccharides |
| DISACCHARIDE | 2 monosaccharide units linked together with the formation of a glycosidic bond and the elimination of water, called a condensation reaction |
| POLYSACCHARIDE | Large, complex molecules called polymers formed from large numbers of monosaccharide units linked together by glycosidic bonds |
| POLAR | Charged molecules that have 2 ends/poles that interact differently to water and fat. A hydrophillic head is attracted to water but not fat, whereas a hydrophobic tail mixes readily with fat but is repelled by water |
| HYDROPHILLIC | Attracts water |
| HYDROPHOBIC | Repels water |
| METABOLIC WATER | Water produced from the oxidation of food. When water is scarce, a camel can metabolise fats |
| TRIGLYCERIDE | Consists of one molecule of glycerol and three fatty acid molecules, and are formed by condensation reactions |
| SATURATED | Contains only single carbon-carbon bonds |
| UNSATURATED | Contains one or more double carbon-carbon bonds |
| R - GROUP | Groups that can vary |
| COHESION | The sticking together of water molecules in a strong lattice framework |
| HIGH SPECIFIC HEAT | Large amount of heat energy is needed to raise the temperature of water because hydrogen bonds between water molecules restrict their movement |
| HIGH LATENT HEAT | Great deal of heat energy is needed to change water from a liquid to a vapour state |
