Terms | Definitions |
|---|---|
 Matter | Anything that occupies space and has mass. comes in gas, liquid, or solid form. |
| Atoms | building blocks making up matter. Combine to form molecules, such as compounds and elements. |
| Protons | +1 electric charge |
| Neutrons | No electric charge |
| Atomic Mass | # of protons and neutrons |
| Atomic Number | # of protons |
| Chemical Reactions | occur when atoms share, donate, or borrow their outter e- with other atoms. |
| Elements | cannot be reduced to smaller form by ordinary chemical reactions |
| Isotopes | Have different atomic masses, but same number of electrons. |
| Radioisotopes | isotopes which are instable and radiate particles or rays of energy. |
| Compound | Two or more elements combine |
| Molecules | Two or more atoms combine |
| Chemical Bonds | Form to make atoms more stable by filling their outter shells. |
| Ionic Bonds | Form when one atom donates electrons and a neighbor atom borrows those electrons. Both become ions. |
| Cation | Positively charged ion. |
| Anion | Negatively charged ion. |
| Covalent Bonds | Atoms share electrons. |
| Organic Compounds | Composed of C-C or C-H covalent bonds. Chains can become huge molecules. Stable in water |
| Inorganic Compounds | Lack C, but all are small molecules that cannot be used to build large structures. Some are unstable in water. |
| Water | The most abundant compound in the body. |
| Dehydration Synthesis | A reaction where one reactant loses a H, the other loses an OH. a water molecule forms. The two leftover fragments bond to form a larger product. Build protein, carbo, and lipids. |
| Hydrolysis | A large product molecule is split into smaller reactants by a small protein called an enzyme. |
| Acids | Dissociate in water into H+ ion and an anion (not an OH), creating an excess of H+ ions. |
| Bases | Dissociate in water into OH- and some cation (but not a H+), creating and excess of OH-, or a decrease of H+ ions. |
| Buffers | Sponge up excess H+ |
| Carbohydrates | means C and H2O. Are made of C, H, O. |
| Monosaccharide | Basic building unit of a carbohydrate. |
| Lipids | Basic building unit is a fatty acid. Forms fats and oils. |
| Triglycerides | Useful in storing energy in cells called adipocytes. |
| Proteins | Basic building unit is the amino acid. |
| Collagen | a connective tissue protein fiber found between cells that holds many body tissues together. |
| Keratin | a waterproof fiber found inside the outer cells of the skin. |
| Glycoproteins | small glycogens attached to large proteins. |
| Lipoproteins | small lipids attached to large proteins. |
| Nucleotides | 4 building units that construct nucleic acids. |
| DNA | Formed by guanine, adenine, cytosine, and thymine |
| RNA | Formed by guainine, adenine, cytosine, and URACIL |
| mRNA | a created "photocopy" of the DNA that leaves the nucleus and goes out into the cell and translates the code into the making of proteins. |
