Chemical Information

FooDB Name

Carbonic acid

Description

Hydrogen carbonate, also known as H2CO3 or [co(OH)2], belongs to the class of organic compounds known as organic carbonic acids. Organic carbonic acids are compounds comprising the carbonic acid functional group. Bicarbonate also acts to regulate pH in the small intestine. Hydrogen carbonate is a very weakly acidic compound (based on its pKa). A parallel example is sodium bisulfite (NaHSO3). Hydrogen carbonate exists in all living species, ranging from bacteria to humans. In humans, hydrogen carbonate is involved in the metabolic disorder called the hartnup disorder pathway. Outside of the human body, Hydrogen carbonate has been detected, but not quantified in, several different foods, such as lovages, lima beans, tree ferns, mountain yams, and burbots. This could make hydrogen carbonate a potential biomarker for the consumption of these foods. As such it is an important sink in the carbon cycle. It is isoelectronic with nitric acid HNO3.
