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
Lactic acid the standard 4 calories per gram that is often used for all carbohydrates. But in some cases lactic acid is ignored in the calculation. The energy density of lactic acid is per 100 g. In beer brewing some styles of beer (sour beer) purposely contain lactic acid. Most commonly this is produced naturally by various strains of bacteria. These bacteria ferment sugars into acids, unlike yeast, who ferment sugar into ethanol. One such style are Belgian Lambics. After cooling the wort, yeast and bacteria are allowed to “fall” into the open fermenters. Most brewers of more common beer styles would
