Homocitric acid is an organic compound with the formula HOC(CO2H)(CH2CO2H)(C2H4CO2H). This tricarboxylic acid occurs naturally as a component of the iron-molybdenum cofactor of certain nitrogenase proteins. Biochemists often refer to this cofactor as homocitrate, which is the conjugate bases that predominate in neutral aqueous solutions of this species. The molecule is related to citric acid by the addition of one methylene unit, hence the prefix "homo." Unlike citric acid, homocitric acid is chiral. The acid exists in equilibrium with the lactone.

  • Homocitric acid is an organic compound with the formula HOC(CO2H)(CH2CO2H)(C2H4CO2H). This tricarboxylic acid occurs naturally as a component of the iron-molybdenum cofactor of certain nitrogenase proteins. Biochemists often refer to this cofactor as homocitrate, which is the conjugate bases that predominate in neutral aqueous solutions of this species. The molecule is related to citric acid by the addition of one methylene unit, hence the prefix "homo." Unlike citric acid, homocitric acid is chiral. The acid exists in equilibrium with the lactone.

  • L'acide homocitrique est un acide tricarboxylique dont la base conjuguée est l'homocitrate, naturellement présent comme composant du cofacteur fer-molybdène de certaines nitrogénases. C'est un homologue de l'acide citrique par addition d'un pont méthylène, d'où le préfixe homo. À la différence de ce dernier, l'acide homocitrique est chiral. Par ailleurs, il est en équilibre avec une forme lactone : (fr)
  • 高柠檬酸(英語:Homocitric acid)是一种化学式为HOC(CO2H)(CH2CO2H)(C2H4CO2H)的有机化合物,这种三元羧酸是某些固氮酶中心的铁钼辅因子的组成成分。生物化学家通常将此辅因子称为高柠檬酸盐,它为铁钼原子提供缀合物碱基,使其在水中呈中性。 高柠檬酸比柠檬酸在分子中间多了一个亚甲基基团,因此称为“高”(拉丁語:homo)。但与柠檬酸不同的是,高柠檬酸是一种手性分子,存在两种对应异构体。此外,高柠檬酸还能自发形成内酯: (zh)
