What Is the Importance of Inorganic Compounds?

Water, an inorganic compound, is important because it makes up as much as 70 percent of the body weight of an adult body, according to a Rice University article published on the Openstax College website. The other groups of inorganic compounds that are essential to the body include salts, acids and bases.

Water is indispensable to human functioning, as it serves as a lubricant and cushion. Many of the body’s lubricating fluids contain water. It lubricates the actions of joints and also helps the lungs expand and contract when breathing. Moreover, it serves as a heat sink, meaning it absorbs and dissipates heat without experiencing a corresponding temperature increase. It is also a major component of liquid mixtures, and it is regarded as the "universal solvent."

Salts are created when ions form ionic bonds. Many salts serve valuable purposes in the body. Calcium phosphate salts form the mineral part of teeth and bones, and bile salts produced by the liver help in breaking down dietary fats.

Acids and bases dissociate in water into electrolytes, like salt. Hydrochloric acid is a strong acid released from cells in the lining of the stomach, and it helps in digestion and kills ingested microbes. The release of bicarbonate, which is a weak base, prevents the small intestine from burning when food is combined with hydrochloric acid from the stomach.
