Carbohydrates | compounds made up of carbon, hydrogen and oxygen in a ratio of 1:2:1. |
Polymerization | the process in which large compounds are built by joining smaller ones together |
Monosaccharide | single sugar unit; the monomer of carbohydrates. |
Polysaccharide | a long chain of monosaccharides joined together. |
Cellulose | a polysaccharide used by plants that provides strength and rigidity. |
Glycogen | a polysaccharide used by animals to store excess sugar. |
Lipids | are fats, oils and waxes; generally not soluble in water and used to store energy. Made up of fatty acids bonded to a glycerol molecule. |
Phospholipids | form biological membranes |
Nucleic Acids | store and transmit hereditary information. |
Two types of nucleic acids | DNA and RNA |
Saturated fatty acid | has the maximum number of hydrogen bonds. |
Unsaturated fatty acid | has less than the maximum number of hydrogen bonds (at least one double bond). |
Protein | polymer that is made up of amino acids |
Amino Acid | the monomer of proteins |
Enzymes | biological catalyts; speed up chemical reactions by lowering activation energy |
activation energy | the amount of energy required to get a reaction to start. |
factors that affect enzyme funciton | temperature, pH, and concentration |
active site | the part of the enzyme that the substrate binds to. |
Substrate | the molecule acted on by an enzyme. |
Products | the result of a chemical reaction. |
polymer | large molecule formed by the joining of individual units or monomers. |
monomer | simplest unit of a biological molecule. |
DNA | dexoyribonucleic acid |
RNA | ribonucleic acid |
