Polymers, monomers, elements, examples
Term | Definition |
---|---|
polymer | a molecule made of many smaller subunits; result of a dehydration reaction |
monomer | small chemical unit (subunit) of a polymer; result of a hydrolysis reaction |
carbohydrates | the biomolecule that provides quick energy for the cell; made of the elements CHO |
lipids | the biomolecule that contains fats, oils, and waxes; made of the elements CHO; can be saturated or unsaturated |
proteins | the biomolecule responsible for cell transport and controlling the rate of chemical reactions (enzymes); made of the elements CHON and sometimes S |
nucleic acids | the biomolecule which contains our genetic information; made of the elements CHONP |
organic compounds | compounds that contain carbon; also called carbon compounds |
carbon compounds | another name for organic compounds because they all contain this element: C |
biomolecule | includes carbohydrates, lipids, proteins, and nucleic acids; found in all living things |
macromolecule | a very large molecule found in all living things |
amino acids | the monomer for proteins; enzymes are an example |
nucleotide | the monomer for nucleic acids; made of a 5-carbon sugar, a phosphate group, and a nitrogenous base |
glycerol and fatty acids (triglyceride) | the monomer for lipids |
molecule | 2 or more atoms covalently bonded together |
monosaccharide | the monomer for carbohydrates; glucose is an example |
polysaccharide | 3 or more monosaccharides joined together; starches such as glycogen, cellulose, and chitin are examples |
disaccharide | 2 monosaccharides joined together; example glucose + fructose = sucrose |
element | a pure substance made of only one type of atom |
mono- | a prefix meaning 1 |
