MeSH: Oxidative Phosphorylation - Finto

Liver mitochondria exhibited a similar phenotype. GDP was also able to raise membrane potential and H 2 O 2 production of the mitochondria from nonparenchymal cells expressing UCP2, but was completely ineffective on mitochondria from hepatocytes deprived of UCP2. 2011-07-08 · 2,4-Dinitrophenol (DNP) is reported to cause rapid loss of weight, but unfortunately is associated with an unacceptably high rate of significant adverse effects. DNP is sold mostly over the internet under a number of different names as a weight loss/slimming aid. It causes uncoupling of oxidative phosphorylation; the classic symptom complex associated with toxicity of phenol-based products 2006-09-12 · The uncoupling proteins 1, 2 and 3 (UCP1, UCP2, and UCP3) are members of the super family of anion carrier proteins located in the inner membrane of mitochondria. UCP1 is found only in brown fat mitochondria of mammals.

Uncoupling agents

The term “uncoupling protein” was originally used for UCP1, which is uniquely present in mitochondria of brown adipocytes, the thermogenic "Uncoupling Agents" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators The invention provides the use of a water-soluble biocide as an uncoupling agent at an effective amount to control bacterial biomass in an aqueous system. The invention also provides a method for controlling the growth of bacterial biomass in an aqueous system. Efficacies and potencies of uncoupling agents.

The uncoupling agent 2,4-dinitrophenol improves mitochondrial homeostasis following striatal quinolinic acid injections It is now generally accepted that excitotoxic cell death involves bioenergetic failure resulting from the cycling of Ca2+ and the generation of reactive oxygen species (ROS) by mitochondria. Uncoupling proteins (UCPs) are mitochondrial transporters present in the inner membrane of mitochondria. They are found in all mammals and in plants.

Chemical agents that uncouple oxidation from phosphorylation in the metabolic cycle so that ATP synthesis does not occur. Included here are those IONOPHORES that disrupt electron transfer by short-circuiting the proton gradient across mitochondrial membranes. Drugs uncoupling agent Any chemical that uncouples the process of respiration from that of phosphorylation. For example, in glycolysis the formation of 3-phosphoglycerate from 3-phosphoglyceroyl phosphate normally yields two molecules of ATP. Salicylic acid is also an uncoupling agent (chiefly in plants) and will decrease production of ATP and increase body temperature if taken in extreme excess. Uncoupling proteins are increased by thyroid hormone , norepinephrine , epinephrine , and leptin . Uncoupling Agents Frikopplingsämnen Engelsk definition. Chemical agents that uncouple oxidation from phosphorylation in the metabolic cycle so that ATP synthesis does not occur.

2,4-Dinitrophenol uncoupling agent Any chemical that uncouples the process of respiration from that of phosphorylation. For example, in glycolysis the formation of 3-phosphoglycerate from 3-phosphoglyceroyl phosphate normally yields two molecules of ATP. However arsenate prevents the formation of ATP at this point. Definition: Chemical agents that uncouple oxidation from phosphorylation in the metabolic cycle so that ATP synthesis does not occur. Included here are those IONOPHORES that disrupt electron transfer by short-circuiting the proton gradient across mitochondrial membranes. enzyme inhib. In a preferred embodiment the method comprises contacting an effective amount of an uncoupling agent which is a water-soluble biocide directly with the bacterial biomass in an aqueous system.

This uncoupling is a hormonally controlled process based on the presence of a mitochondrial proton channel called thermogenin. The hormone norepinephrine increases production of free fatty acids, which open the thermogenin channel. Mitochondrial uncoupling can be defined as a dissociation between mitochondrial membrane potential generation and its use for mitochondria-dependent ATP synthesis. Although this process was originally considered a mitochondrial dysfunction, the identification of UCP-1 as an endogenous physiological uncoupling protein suggests that the process could be involved in many other biological Agents which uncouple oxidative phosphorylation in mitochondria were applied to identified neurons in an isolated ganglion of the marine molluscNavanax inermis. Aromatic monocarboxylic acids, acetanilides, benzamides, benzaldehydes and phenols all caused a rapid, reversible, dose-dependent increase in the membrane potential and conductance of the neurons tested. An uncoupling agent reversed this effect. Liver mitochondria exhibited a similar phenotype.

Uncoupling Agents Subject Areas on Research Interference of Uncoupling Agents with Cellular Energy-requiring Processes in Anaerobic Conditions. T. GALEOTTI 1,2, L. KOVÁĈ 1,3 & B. HESS 1 Nature volume 218, pages 194–196(1968)Cite this This is accomplished by uncoupling the electron transport chain from the ATP synthesis. This uncoupling is a hormonally controlled process based on the presence of a mitochondrial proton channel called thermogenin.
