Cannabis Compound Identification
Common NameHydrogen carbonate
DescriptionHydrogen 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. Hydrogen carbonate is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Molecular weight:
60058.5
General function:
Involved in secondary active sulfate transmembrane transporter activity
Specific function:
Motor protein that converts auditory stimuli to length changes in outer hair cells and mediates sound amplification in the mammalian hearing organ. Prestin is a bidirectional voltage- to-force converter, it can operate at microsecond rates. It uses cytoplasmic anions as extrinsic voltage sensors, probably chloride and bicarbonate. After binding to a site with millimolar affinity, these anions are translocated across the membrane in response to changes in the transmembrane voltage. They move towards the extracellular surface following hyperpolarization, and towards the cytoplasmic side in response to depolarization. As a consequence, this translocation triggers conformational changes in the protein that ultimately alter its surface area in the plane of the plasma membrane. The area decreases when the anion is near the cytoplasmic face of the membrane (short state), and increases when the ion has crossed the membrane to the outer surface (long state). So, it acts as an incomplete transporter. It swings anions across the membrane, but does not allow these anions to dissociate and escape to the extracellular space. Salicylate, an inhibitor of outer hair cell motility, acts as competitive antagonist at the prestin anion-binding site
