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
Muricholic acid (to give gly-murocholic acids) takes place in the liver before secretion. Tauro-muricholic acids were shown to be potent antagonists of the bile acid receptor farnesoid X receptor (FXR). Muricholic acid Muricholic acids are a group of bile acids found as one of the main forms in mice, which gives them their name, and at low concentrations in other species. Muricholic acids differ from the more common bile acids, such as cholic acid or chenodeoxycholic acid, by having a hydroxyl group at the 6-position. They are detectable at low concentrations in human urine. The three major bile acids in germ-free mice
