(ăn′ə-lôg′, -lŏg′)
1. Biology An organ or structure that is similar in function to one in another kind of organism but is of dissimilar evolutionary origin.
2. Chemistry A structural derivative of a parent compound that often differs from it by a single element.
Of, relating to, or being a device in which data or a signal is represented by continuously variable, measurable, physical quantities, such as length, width, voltage, or pressure.

noun A compound that is structurally similar to another.

adjective An MRI term referring to or having a continuous range of values.

adjective Referring to data in the form of continuously variable (non-discrete) physical quantities, the mode in which most lab instruments produce information, where data is generated as non-discrete signals, as in AC or DC current, voltage changes or pulse amplitudes.

Molecular biology
adjective Referring to a molecule that is structurally and functionally related to another molecule.

noun A molecule that is structurally and functionally related to another molecule.    

noun A therapeutic agent with structural or chemical similarity to, or which mimics the effects of, another agent, but which differs chemically.

, analog (an'ă-lawg)
1. One of two organs or parts in different species of animals or plants that differ in structure or development but are similar in function.
2. A compound that resembles another in structure but is not necessarily an isomer; analogues are often used to block enzymatic reactions by combining with enzymes.
