The main constituent of gastric acid is hydrochloric acid which is produced by parietal cells (also called oxyntic cells) in the gastric glands in the stomach.Its secretion is a complex and relatively energetically expensive process.he pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, the acidity being maintained by the proton pump H+/K+ ATPase. The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline tide.
According to Arrhenius, acids produce a proton in aqueous solution, and bases produce a hydroxide ion in aqueous solution. Hydrochloric acid is an Arrhenius acid because it gives up its proton as it dissolves in water.
