| Question | Answer |
|---|---|
| molecules that coontain carbon | organic molecules |
| what are the four groups of organic molecules | carbohydrates, lipids, proteins and nucleic acids |
| molecules used for energy, storage of energy and cellular structures | carbohydrates |
| carbohydrates are composed of | atoms of carbon, hydrogen, oxygen, |
| the simplist (simple sugar) form of carbohydrate is called | monosaccharide |
| two monosaccharides joined together in a synthesis reaction is called a | disaccharide |
| the combination of two or more simple materials to form one or more complex materisla by removing water | dehydration synthesis |
| breaks down more complex materials into simpler ones by adding water | hydrolysis |
| a combination of many monosaccharides joined together by dehydration synthesis | polysaccharides |
| used by the body for energy and are stored in fat for future energy needs | lipids |
| four classes of lipids | neutral fats, phospholipids, steriods, eicosanoids |
| lipids are composed of | carbon,hydrogen, oxygen and sometimes phosphorous |
| a lipid composed of three fatty acids and a glycerol | neutral fat or triglyceride |
| a chain of carbon atoms attached to each carbon by a single or double bonds | fatty acid |
| when all the bonds in the hydrcarbon chain fats that have single bonds so as many hydrogen atoms as possible are attached to the carbon. found mainly in animal fats. | saturated fatty acid |
| fats that have some double bonds between carbon and and hydrogen atoms. found mainly in plants | unsaturated fatty acid |
| a macro molecule composed of proteins and lipids | lipoprotein |
| composed of two fatty acids attached to glycerol and a phosphate group | phospholipids |
| steroids |
