Analog - in Science

In Science

• Analogical models, mathematical models applied in the analysis of dynamical systems
• Analogy (biology), biological structures which perform similar functions by similar mechanisms but evolved separately
• Functional analog, a chemical compound with similar properties
• No-analog (ecology), in paleoecology and ecological forecasting, a description of climatic conditions or biological communities with no current counterparts
• Structural analog, a chemical compound with a slightly altered chemical structure
• Substrate analog, a chemical compound that resembles the substrate in an enzymatic reaction
• Transition state analog, a chemical compound that resembles the transition state of a substrate in an enzymatic reaction
