Document Summary

Isotope: elements with different numbers of neutrons shell which interact with other electrons on other atoms. Hydrogen bonds: formed when a hydrogen atom is shared between two molecules, frequently found in proteins and nucleic acids, by reinforcing each other, they serve to keep the protein structure secure. Ionic bonds: formed when electrons are completely transferred from one atom to another; the result is 2 ions, one positively charged and one negatively charged. Van der waals bonds: extremely weak bonds that from between nonpolar molecules or non polar parts of a molecule, created because of a c-h bond. Molecules: smallest identifiable unit into which a pure substance can be divided and still remain the composition and chemical properties of that substance. Metabolism: metabolism: general term used for all chemical reactions that occur in living systems, anabolism: synthesis of compounds, catabolism: breakdown of compounds. Involves carbon-containing molecules: all carbon atoms have four bonds to account for.
