| analog | 1. One of two organs or parts in different species of animals or plants which differ in structure or development but are similar in function. 2. A compound that resembles another in structure but is not necessarily an isomer (e.g., 5-fluorouracil is an analog of thymine); analog's are often used to block enzymatic reactions by combining with enzymes (e.g., isopropyl thiogalactoside vs. Lactose). Synonym: analogue. Origin: G. Analogos, proportionate (05 Mar 2000) |
| analog-digital conversion | The process of converting analog data such as continually measured voltage to discrete, digital form. (12 Dec 1998) |
| analogous | According to a due ratio, conformable, proportionate, resembling or similar in some respects, as in function or appearance, but not in origin or development. Compare: homologous. Origin: Gr. Analogos (18 Nov 1997) |
| analogue | <chemistry> A compound that is structurally similar to another. (10 Jan 1998) |
| analogy | <biology> Two anatomical structures or behavioural traits within different and unrelated organisms which perform the same functions in each organism but which did not originate from an ancestral structure or trait that the organisms' ancestors had in common. Instead, the structures or traits arose separately and then later evolved to perform the same function (or similar functions). See: convergent evolution. Compare: homology. (09 Oct 1997) |
| analphalipoproteinaemia | Familial high {density lipoprotein deficiency}; a heritable disorder of lipid metabolism characterised by almost complete absence from plasma of high density lipoproteins, and by storage of cholesterol esters in foam cells, tonsillar enlargement, an orange or yellow-gray colour of the pharyngeal and rectal mucosa, hepatosplenomegaly, lymph node enlargement, corneal opacity, and peripheral neuropathy; autosomal recessive inheritance.

| analyser | <microscopy> An optical device, capable of producing plane polarized light, used for detecting the state of polarization. A second polarizing element inserted beyond a preparation. When its vibration direction is at right angles to the vibration direction of the polarize, the field becomes black if no anisotropic specimen is on the stage or when viewing an anisotropic substance in an extinction position or directly down an optic axis of an anisotropic crystal. (05 Aug 1998) |
| analysis | <technique> The separation into component parts or elements, the act of determining the component parts of a substance. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
