| acid | a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically, a corrosive or sour-tasting liquid of this kind |
| atom | the basic unit of a chemical element |
| base | the lowest part or edge of something, esp. the part on which it rests or is supported |
| compound | a thing that is composed of two or more separate elements; a mixture |
| convalent bond | a chemical bond that involves sharing a pair of electrons between atoms in a molecule |
| element | a part or aspect of something abstract, esp. one that is essential or characteristic |
| ion | an atom or molecule with a net electric charge due to the loss or gain of one or more electrons |
| ionic bond | a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion |
| isotope | ontain equal numbers of protons but different numbers of neutrons in their nuclei |
| metabolism | the chemical processes that occur within a living organism in order to maintain life |
| mixture | a substance made by mixing other substances together |
| nucleus | the central and most important part of an object, movement, or group, forming the basis for its activity and growth |
| pH | standard activity |
| solution | a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent). |
| diffusion | the spreading of something more widely |
| dynamic equilibrium | a state of balance between continuing processes. |
| hydrogen bond | a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other |
| polar molecule | polarity refers to a separation of electric charge leading to a molecule having an electric dipole |
| amino acids | a simple organic compound containing both a carboxyl (-COOH) and an amino (-NH2) group. |
| carbohydrates | any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose |
| enzymes | a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. |
| isomer | each of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties |
| lipid | any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents |
| nucleic acids | a complex organic substance present in living cells |
| nucleotide | monimer of nucleac acid a compound consisting of a nucleoside linked to a phosphate group |
| peptide bond | the primary linkage of all protein structures |
| polymer | a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together |
| protein | any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms |
