| 설명 | 1. 같은 원자 번호와 질량수를 가지면서 반감기, 에너지 상태, 방사능의 성질이 다른 원자핵. 2. 분자식은 같지만 다른 물리적-화학적 성질을 갖는 화합물. 분자 안에서 원자의 배열 방식이 다르기 때문에 이러한 화합물이 생긴다. |

| isomer | 1. <chemistry> One of two or more molecules that have the same chemical formula but have a different stereochemical arrangement of their atoms. 2. <radiobiology> Nuclides having the same number of neutrons and protons but capable of existing, for a measurable time, in different quantum states with different energies and radioactive properties. Commonly, the isomer of higher energy decays to one of lower energy by the process of isomeric transition. (13 Nov 1997) |
|---|---|
| isomerase | <enzyme> An enzyme that converts molecules into their positional isomers. (09 Oct 1997) |
| isomerases | <enzyme> A class of enzymes that catalyze geometric or structural changes within a molecule to form a single product. The reactions do not involve a net change in the concentrations of compounds other than the substrate and the product. Registry number: EC 5. (12 Dec 1998) |
| isomeric | <chemistry> Having the same percentage composition; said of two or more different substances which contain the same ingredients in the same proportions by weight, often used with with. Specif., Polymeric; i. E, having the same elements united in the same proportion by weight, but with different molecular weights; as, acetylene and benzine are isomeric (polymeric) with each other in this sense. See Polymeric. Metameric; i. E, having the same elements united in the same proportions by weight, and with the same molecular weight, but which a different structure or arrangement of the ultimate parts; as, ethyl alcohol and methyl ether are isomeric (metameric) with each other in this sense. See Metameric. Origin: Iso- + Gr. Part: cf. F. Isomerique. Source: Websters Dictionary (01 Mar 1998) |
| isomeric function | The individual function of an isolated segment of the spinal cord. (05 Mar 2000) |
| isomeric transition | The transition of a nuclear isomer to a lower quantum state; e.g., 131mXe → 131Xe + g. (05 Mar 2000) |
| isomeride | <chemistry> An isomer. Source: Websters Dictionary (01 Mar 1998) |
| isomerism | A condition in which several chemical compounds have the same molecular formula (have the same number and type of atoms) but, because those atomsare arranged differently in each, they all have different chemical properties. (09 Oct 1997) |
| isomerization | A process in which one isomer is formed from another, as in the action of isomerases. Enzyme isomerization, reversible changes in enzyme conformation. (05 Mar 2000) |
| isomeromorphism | <chemistry> Isomorphism between substances that are isomeric. Origin: Isomer + Gr. Form + -ism. Source: Websters Dictionary (01 Mar 1998) |
| isomerous | <chemistry> Having the same percentage composition; said of two or more different substances which contain the same ingredients in the same proportions by weight, often used with with.

E, having the same elements united in the same proportion by weight, but with different molecular weights; as, acetylene and benzine are isomeric (polymeric) with each other in this sense.

| geometric isomer | <chemistry> Geometric or also called cis-trans isomers are stereoisomers in molecules with restricted rotation about a bond. Cycloalkanes and alkenes form cis-trans isomers due to the restriction of rotation about the double bond or due to the restriction in a ring. In order for an alkene to freely rotate, the pi bond must be broken. This process has a high activation energy and does not occur at room temperature. Cis isomers have the two substituents on each of the carbons of the double bond on the same side, whereas in the trans isomer they are on opposite sides. The expression cis and trans only applies to alkenes or cycloalkanes if one of the substituents on each of the carbons are the same. If there are three or four different substituents, E,Z or R,S nomenclature must be used. (09 Jan 1998) |
|---|---|
| chain isomer | <chemistry> One of two or more compounds having the same chemical composition but differing in the arrangement of the atoms (usually carbon atoms) forming the backbone of the structure of the compounds. (21 Mar 1998) |
| dextrorotatory isomer | A stereoisomer that does a clockwise rotation of plane-polarized light. (09 Oct 1997) |
| levorotatory isomer | A stereoisomer that rotates the plane of polarized light counterclockwise. (09 Oct 1997) |
