Gastric juice is a strong acidic liquid, pH 1 to 3 in humans, which is close to being colourless. In Computer science, ACID ( Atomicity Consistency Isolation Durability) is a set of properties that guarantee that Database transactions are pH is the measure of the acidity or alkalinity of a Solution. The hormone gastrin is released into the bloodstream when peptides are detected in the stomach. In humans gastrin is a Hormone that stimulates secretion of Gastric acid (HCl by the Parietal cells of the Stomach, as well as aiding in Peptides (from the Greek πεπτίδια, "small digestibles" are short Polymers formed from the linking in a defined order of α- Amino This causes gastric glands in the lining of the stomach to secrete gastric juice. In Human anatomy, the stomach is a J-shaped hollow muscular organ of the Gastrointestinal tract involved in the second phase of Digestion, following Its main components are digestive enzymes pepsin and rennin, hydrochloric acid, and mucus. Pepsin is a digestive Protease ( released by the chief cells in the Stomach that functions to degrade food Proteins into Chymosin (or rennin) is an aspartic acid protease Enzyme found in Rennet. Hydrochloric acid is the Solution of Hydrogen chloride ( H[[Chlorine Cl]] in water In vertebrates mucus is a slippery secretion produced by and covering Mucous membranes It is a viscous Colloid containing Antiseptic enzymes (such as [1]
