Chemical Information
FooDB Nameformate
DescriptionFormate, also known as formic acid or methanoic acid, is a member of the class of compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Formate is soluble (in water) and a weakly acidic compound (based on its pKa). Formate can be found in a number of food items such as mammee apple, chicory roots, malabar spinach, and grapefruit, which makes formate a potential biomarker for the consumption of these food products. Formate (IUPAC name: methanoate) is the anion derived from formic acid. Its formula is represented in various equivalent ways: CHOO− or HCOO− or HCO2−. It is the product of deprotonation of formic acid. It is the simplest carboxylate anion. A formate (compound) is a salt or ester of formic acid .
