Organic Molecules
| Term | Definition |
|---|---|
| Acid | |
| Atom | the smallest particle of an element that can exist either alone or in combination |
| Base | Any substance that forms hydroxide ions in water. |
| Compund | A substance that is composed of atoms of two or more different elements that are chemically combined. |
| Covalent Bonds | a chemical bond formed between atoms by the sharing of electrons |
| Element | any of the fundamental substances that consist of atoms of only one kind and that singly or in combination constitute all matter |
| Ion | an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons |
| Ionic Bond | a chemical bond formed between oppositely charged species because of their mutual electrostatic attraction |
| Isotope | any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties |
| Metabolism | the chemical changes in living cells by which energy is provided for vital processes and activities and new material is assimilated |
| Mixture | a portion of matter consisting of two or more components in varying proportions that retain their own properties |
| Molecule | the smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms |
| Nucleus | the positively charged central portion of an atom that comprises nearly all of the atomic mass and that consists of protons and usually neutrons |
| pH | a measure of acidity and alkalinity of a solution that is a number on a scale on which a value of 7 represents neutrality and lower numbers indicate increasing acidity and higher numbers increasing alkalinity |
| Solution | an act or the process by which a solid, liquid, or gaseous substance is homogeneously mixed with a liquid or sometimes a gas or solid |
| Diffusion | the process whereby particles of liquids, gases, or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration |
| Dynamic Equilibrium | This condition, in which there is continous movement but no overall concentration change. |
| Amino Acid | an amphoteric organic acid containing the amino group NH2; especially |
| Carbohydrate | any of various neutral compounds of carbon, hydrogen, and oxygen (as sugars, starches, and celluloses) most of which are formed by green plants and which constitute a major class of animal foods |
| Enzyme | any of numerous complex proteins that are produced by living cells and catalyze specific biochemical reactions at body temperatures |
| Isomer | one of two or more compounds, radicals, or ions that contain the same number of atoms of the same elements but differ in structural arrangement and properties |
| Lipid | any of various substances that with proteins and carbohydrates constitute the principal structural components of living cells, and that include fats, waxes, phosphatides, cerebrosides, and related and derived compounds |
| Nucleic Acid | |
| Nucleotide | |
| peptide Bond | |
| Polymer | |
| Protein |
