1Endergonic reaction — In chemical thermodynamics, an endergonic reaction (also called an unfavorable reaction or a nonspontaneous reaction) is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed. In layman s terms the… …
2Nazarov cyclization reaction — The Nazarov cyclization reaction (often referred to as simply the Nazarov cyclization) is a chemical reaction used in organic chemistry for the synthesis of cyclopentenones. The reaction is typically divided into classical and modern variants,… …
3Ene reaction — The Ene reaction (also known as the Alder ene reaction) is a chemical reaction between an alkene with an allylic hydrogen (the ene) and a compound containing a multiple bond (the enophile), in order to form a new σ bond with migration of the ene… …
4Hydroboration-oxidation reaction — In organic chemistry, the hydroboration oxidation reaction is a two step organic chemical reaction that converts an alkene into a neutral alcohol by the net addition of water across the double bond. [cite book author = Loudon, Marc G. year = 2002 …
5Dowd-Beckwith ring expansion reaction — The Dowd Beckwith Ring Expansion Reaction is an organic reaction in which a cyclic β keto ester is expanded by up to 4 carbons in a free radical ring expansion reaction through an α alkylhalo substituent Ref|Dowd1 Ref|Dowd2 Ref|Beckwith1. The… …
6Dowd–Beckwith ring expansion reaction — The Dowd–Beckwith ring expansion reaction is an organic reaction in which a cyclic β keto ester is expanded by up to 4 carbons in a free radical ring expansion reaction through an α alkylhalo substituent [1] [2] …
7Photophosphorylation — through light dependent reactions of photosynthesis at the thylakoid membrane The production of ATP using the energy of sunlight is called photophosphorylation. Only two sources of energy are available to living organisms: sunlight and reduction… …
8Organic matter — Other meanings can be found at Biological material Organic matter (or organic material, Natural Organic Matter, or NOM) is matter that has come from a once living organism; is capable of decay, or the product of decay; or is composed of organic… …
9Natural organic matter — (NOM) is broken down organic matter that comes from plants and animals in the environment. [ Natural Organic Matter, GreenFacts, 22 Apr, 2007 …
10Electrochemical gradient — An electrochemical gradient is a spatial variation of both electrical potential and chemical concentration across a membrane; that is, a combination of the membrane potential (delta psi) and the pH gradient (delta pH). Both components are often… …
