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 |
