| twist | 1. The act of twisting; a contortion; a flexure; a convolution; a bending. "Not the least turn or twist in the fibres of any one animal which does not render them more proper for that particular animal's way of life than any other cast or texture." (Addison) 2. The form given in twisting. "[He] shrunk at first sight of it; he found fault with the length, the thickness, and the twist." (Arbuthnot) 3. That which is formed by twisting, convoluting, or uniting parts. Specifically: A cord, thread, or anything flexible, formed by winding strands or separate things round each other. A kind of closely twisted, strong sewing silk, used by tailors, saddlers, and the like. A kind of cotton yarn, of several varieties. A roll of twisted dough, baked. A little twisted roll of tobacco. One of the threads of a warp, usually more tightly twisted than the filling. A material for gun barrels, consisting of iron and steel twisted and welded together; as, Damascus twist. The spiral course of the rifling of a gun barrel or a cannon. A beverage made of brandy and gin. 4. [OE.; so called as being a two-forked branch. See Twist] A twig. Gain twist, or Gaining twist, a twist of which the spiral course has an equal pitch throughout. Source: Websters Dictionary (01 Mar 1998) |

| carbohydrate conformation | The characteristic 3-dimensional shape of a carbohydrate. (12 Dec 1998) |
| molecular conformation | The characteristic three-dimensional shape of a molecule. (12 Dec 1998) |
| conformation | The three-dimensional arrangement of side groups on a molecule which canfreely rotate into different positions without breaking any bonds. (09 Oct 1997) |
| protein conformation | The characteristic 3-dimensional shape of a protein, imposed upon it by the secondary and tertiary structure of the peptide chain. This stage in the structure of a protein describes the highest level of organization in overall structure assumed by multimeric proteins (aggregates of more than one polypeptide chain). This is the fourth folding level of protein building. (12 Dec 1998) |
| native conformation | <chemistry> The conformation in which a molecule is biologically active. (09 Oct 1997) |
| nucleic acid conformation | The characteristic 3-dimensional shape of a nucleic acid or polynucleotide. Its secondary structure is due to the formation of hydrogen bonds between nucleotides, resulting in base pairing and areas with alpha helix structure. (12 Dec 1998) |
