| immunoglobulins, heavy-chain | Major components of immunoglobulin molecules. They are the larger of the two types of polypeptide chains responsible for the biological and immunological properties of the different immunoglobulins. They differ according to the class of ig from which they were isolated, contain 450 to 600 amino acid residues per chain, and have molecular weights of 51-72 kD. One ig molecule comprises two heavy and two light chains. (12 Dec 1998) |

| alkali earth metal | See: alkaline earth elements. (05 Mar 2000) |
| alkali metal | <chemistry> Any of the highly reactive metals (such as sodium or potassium) found in the first column of the periodic table, these metals act as bases. (13 Nov 1997) |
| Babbitt metal | An alloy of antimony, copper, and tin; used occasionally in dentistry. (05 Mar 2000) |

| metal | 1. <chemistry> An elementary substance, as sodium, calcium, or copper, whose oxide or hydroxide has basic rather than acid properties, as contrasted with the nonmetals, or metalloids. No sharp line can be drawn between the metals and nonmetals, and certain elements partake of both acid and basic qualities, as chromium, manganese, bismuth, etc. Popularly, the name is applied to certain hard, fusible metals, as gold, silver, copper, iron, tin, lead, zinc, nickel, etc, and also to the mixed metals, or metallic alloys, as brass, bronze, steel, bell metal, etc. 2. Ore from which a metal is derived; so called by miners. 3. A mine from which ores are taken. "Slaves . . . And persons condemned to metals." (Jer. Taylor) 4. The substance of which anything is made; material; hence, constitutional disposition; character; temper. "Not till God make men of some other metal than earth." (Shak) 5. Courage; spirit; mettle. See Mettle. The allusion is to the temper of the metal of a sword blade. 6. The broken stone used in macadamizing roads and ballasting railroads. 7. The effective power or calibre of guns carried by a vessel of war. 8. Glass in a state of fusion. 9. The rails of a railroad. <mathematics> Base metal, an alloy resembling brass, consisting of three parts of copper to one of zinc; also called Prince Rupert's metal. Origin: F. Metal, L. Metallum metal, mine, Gr. Mine; cf. Gr. To search after. Cf. Mettle, Medal. Source: Websters Dictionary (01 Mar 1998) |
| metal base | A metallic portion of a denture base forming a part of the wall of the basal surface of the denture; it serves as a base for the attachment of the plastic (resin) part of the denture and the teeth. (05 Mar 2000) |
| metal ceramic alloys | The fusion of ceramics (porcelain) to an alloy of two or more metals for use in restorative and prosthodontic dentistry. Examples of metal alloys employed include cobalt-chromium, gold-palladium, gold-platinum-palladium, and nickel-based alloys. (12 Dec 1998) |
| heavy metals |
Metallic elements with high molecular weights. Such metals are often residual in the environment, exhibit biological accumulation, and are generally toxic in low concentrations. Examples include chromium, mercury, and lead.
