Term | Definition |
Acid | any compound that increases the number of hydronium ions when disolved in water; any of various water-soluble compounds having a sour taste and capable of turning litmus red and reacting with a base to form a salt |
Alkaline | a solution that has a pH value greater than 7 because of the dissociation of a base in water to produce hydroxide ions. |
Atom | The smallest unit of an element that maintains the chemical properties of that element. |
Base | any compound that increases the number of hydroxide ions when dissolved in water; bases turn red litmus paper blue and react with acids to form salts |
Carbohydrate | any organic compound that is made of carbon, hydrogen, and oxygen and that provides nutrients to the cells of living things |
Catalyst | a substance that changes the rate of a chemical reaction without being consumed or changed significantly |
Chemical Bond | The attractive force that holds atoms or ions together. |
Compound | a substance made up of two or more different elements joined by chemical bonds |
Element | a substance that cannot be separated or broken down into simpler substances by chemical means |
Lipid | a type of biochemical that does not dissolve in water, including fats and steroids; lipids store energy and make up cell membranes |
macromolecule | a very large organic molecule, usually a polymer, composed of hundreds or thousands of atoms |
Molecule | a group of atoms that are held together by chemical forces; a molecule is the smallest unit of matter that can exist by itself and retain all of a substances chemical properties. |
Neutral | having only a limited ability to react chemically; having no net electric charge; pH value of 7 |
Nucleic Acid | an organic compound, either RNA or DNA, whose molecules are made up of one or two chains of nucleotides and carry genetic information |
pH | a value that is used to express the acidity or alkalinity(basicity) of a system; a pH of 7 is neutral, a pH of less than 7 is acidic, and a pH of greater than 7 is basic. |
Protein | an organic compound that is made of one or more chains of amino acids and that is a principal component of all cells. |
