organic molecule that contains carbon, hydrogen, and oxygen and provides energy to cells
weak intermolecular force that results from an attraction between a positively charged hydrogen atom in one molecule and a negatively charged atom in a nearby molecule
one of two or more atoms of an element that have the same number of protons but different numbers of neutrons
chemical reaction in which an acid and a base in solution interact, producing salt and water and changing the pH
molecule made of nucleotides. It exists in cells in two forms: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
polar covalent bond
