Glossary of Chemical Terms - G
- The process of covering iron with a coat of zinc to make it less reactive to air and water.
- A device that is very sensitive and able to detect even small flows of electrons through a wire.
- The least dense state of matter.
- gas chromatography
- An analytical chemistry technique in which a sample is vaporized and passed through a column whose walls are covered with a sticky organic solvent; different chemicals in the sample have different affinities for the solvent and separate as they pass through the column.
- A mixture of 90% gasoline and 10% ethyl alcohol that is used as an automotive fuel.
- A volatile, flammable, liquid mixture of hydrocarbons, obtained from petroleum, and used as fuel for internal-combustion engines.
- A colloid in which the dispersed phase has combined with the continuous phase to produce a semisolid material as a jelly; a colloid formed by coagulation of a sol.
- The fundamental physical and functional unit of heredity. A gene is an ordered sequence of nucleotides located in a particular position on a particular chromosome that encodes a specific functional product (i.e., a protein or RNA molecule).
- A 6-carbon sugar that plays a major role in cell metabolism.
- A polysaccharide the body uses for energy storage; it is made up of chains of glucose molecules. When the body has depleted the free glucose in the blood, the liver breaks down glycogen into more glucose.
- A lipid covalently linked to a sugar or polysaccharide. These biomolecules are important parts of animal cell membranes.
- A complex biochemical process in which one molecule of glucose is anaerobically converted into two molecules of pyruvate and energy in the form of ATP.
- The basic unit of mass in the metric system.
- The most stable allotrope, or form of carbon, having a hexagonal type linking of atoms with relatively strong bonds to 3 neighboring carbon atoms, and a much weaker bond to a fourth carbon atom.
- A vertical column in the periodic table.
