Adenosylcobalamin (original) (raw)
L'adénosylcobalamine, également appelée cobamamide, adocobalamine, voire dibencozide, est l'une des formes actives de vitamine B12, avec la méthylcobalamine. Elle est disponible commercialement sous forme de comprimés, mais pas sous forme injectable, contrairement aux trois autres formes de vitamine B12 (méthylcobalamine, hydroxocobalamine et cyanocobalamine). La méthylmalonyl-CoA mutase est une enzyme qui utilise l'adénosylcobalamine comme cofacteur.

| dbo:abstract | Adenosylcobalamin (AdoCbl), also known as coenzyme B12, cobamamide, and dibencozide, is, along with methylcobalamin (MeCbl), one of the biologically active forms of vitamin B12. Adenosylcobalamin participates as a cofactor in radical-mediated 1,2-carbon skeleton rearrangements. These processes require the formation of the deoxyadenosyl radical through homolytic dissociation of the carbon-cobalt bond. This bond is exceptionally weak, with a bond dissociation energy of 31 kcal/mol, which is further lowered in the chemical environment of an enzyme active site. An enzyme that uses adenosylcobalamin as a cofactor is methylmalonyl-CoA mutase (MCM). Further experimentation has also determined adenosylcobalamin's role in regulating expression of some bacterial genes. By binding to CarH, AdoCbl can modulate carotenoid genes, which confer warm colors onto various plants. Carotenoid transcription is activated by sunlight, due to the response from AdoCbl. There are other photoreceptors across different bacterial communities, aside from CarH, that also have reactive capability when bound to AdoCbl. For instance, AerR is another factor that uses AdoCbl to give off purple pigmentation. Additional examination of adenosylcobalamin-bound enzymes and the development of this cofactor over time may prove to hold regulatory function of DNA and RNA. (en) La cobamamida es una coenzima de la vitamina B12, presente en varios tejidos animales y en tejidos humanos. También se conoce como adenosilcobalamina y dibencozida. Posee la propiedad de intervenir en los procesos metabólicos de síntesis proteica (metabolismo de las proteínas), especialmente los realizados en el hígado, siendo esencial para el crecimiento y el eutrofismo del parénquima hepático. Estimula el anabolismo celular, activando la síntesis proteica y favoreciendo el uso de glúcidos y lípidos. Bien tolerada por el organismo humano, se diferencia de otras sustancias anabolizantes, como los esteroides, por no generar efectos colaterales como virilización, pseudohermafroditismo o ginecomastia, entre otros. Posee acción moderada contra la anemia y sobre el sistema nervioso central y periférico, como neurotrófico y neurorregenerador. Es una sustancia muy bien tolerada por el organismo, casi desprovista de efectos colaterales. Actúa atenuando ciertos disturbios metabólicos del crecimiento, siendo muchas veces prescrito por los médicos a pacientes preadolescentes con dificultad en su desarrollo.

È utilizzato sia in campo medico che veterinario, dove viene utilizzato come anabolizzante, nei ritardi della crescita o di insufficienti o stentati incrementi ponderali. Trova impiego anche come ricostitutivo nella convalescenza, iporessia ed anoressia. Usato anche come coadiuvante nelle epatopatie e neuropatie, come stimolante nella sindrome da fatica e con scarso rendimento negli animali atleti, come cavalli e cani. (it) Adenosylcobalamine, ook wel co-enzym B12 of cobamamide (AdoCbl), is een van de biologisch actieve vormen van vitamine B12. Samen met de andere cobalamines is het een complexe organische verbinding die van groot belang is voor diverse stofwisselingsprocessen. Adenosylcobalamine is in veel landen in tabletvorm verkrijgbaar. Adenosylcobalamine neemt als cofactor deel aan herschikkingen van het koolstofskelet van diverse verbindingen. Deze herschikkingen vereisen de vorming van een desoxyadenosylradicaal door homolytische splitsing van de koolstof-kobalt-binding. Deze binding is zeer zwak: het heeft een bindingsdissociatie-energie van 31 kcal/mol, en deze energiewaarde wordt nog lager wanneer het in de buurt komt van het enzymatisch actieve centrum. Een belangrijk enzym dat adenosylcobalamine als cofactor gebruikt, is methylmalonyl-CoA-mutase (MCM), dat in de mitochondria verantwoordelijk is voor de oxidatie van aminozuren met een vertakte keten.

Atua nos distúrbios metabólicos do crescimento, sendo muitas vezes prescrita para pacientes pré-adolescentes com dificuldade em seu desenvolvimento. Também utilizado por fisiculturistas como alternativa a anabolizantes esteróides, que oferecem grandes riscos à saúde. (pt) Кобаламид (англ. Adenosylcobalamin (AdoCbl)) — витамин, также известный как аденозилкобаламин и дибенкозид. Вместе с метилкобаламином (MeCbl) является одной из активных форм витамина B12. В качестве пищевой добавки доступен в форме таблеток, но (в отличие от цианкобаламина, метилкобаламина и гидроксокобаламина) его невозможно вводить в кровь напрямую. Отличается от цианокобаламина тем, что атом кобальта в последнем присоединен к цианогруппе. (ru) |
