Formic acid Formic acid Formic acid, systematically named methanoic acid, is the simplest carboxylic acid. The chemical formula is HCOOH or HCOH. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. The word "formic" comes from the Latin word for ant, "formica", referring to its early isolation by the distillation of ant bodies. Esters, salts, and the anion derived from formic acid are called formates. Industrially formic acid is produced from methanol. Formic acid is a colorless liquid having a pungent, penetrating odor at room temperature, not unlike the related acetic acid. It is miscible
Adenosylcobyric acid synthase (glutamine-hydrolysing) Adenosylcobyric acid synthase (glutamine-hydrolysing) In enzymology, an adenosylcobyric acid synthase (glutamine-hydrolysing) () is an enzyme that catalyzes the chemical reaction The 4 substrates of this enzyme are ATP, adenosylcobyrinic acid a,c-diamide, L-glutamine, and HO, whereas its 4 products are ADP, phosphate, adenosylcobyric acid, and L-glutamate. This enzyme belongs to the family of ligases, specifically those forming carbon-nitrogen bonds carbon-nitrogen ligases with glutamine as amido-N-donor. The systematic name of this enzyme class is adenosylcobyrinic-acid-a,c-diamide:L-glutamine amido-ligase (ADP-forming). Other names in common use include CobQ, cobyric acid synthase, 5'-deoxy-5'-adenosylcobyrinic-acid-a,c-diamide:L-glutamine, amido-ligase, and Ado-cobyric acid synthase [glutamine hydrolyzing]. This enzyme participates in porphyrin and chlorophyll
