单词	pepsinogen
释义	pepsinogen /pɛpˈsɪnədʒ(ə)n / noun [mass noun] Biochemistry A substance which is secreted by the stomach wall and converted into the enzyme pepsin by gastric acid: serum pepsinogen [count noun]: high concentrations of pepsinogens... In the stomach, pepsinogen is secreted, and activated into pepsin by the acid that is secreted at the same site. Examples of important proenzymes include pepsinogen, trypsinogen and chymotrypsinogen, which give rise to the proteolytic digestive enzymes. Ginger is an excellent natural antacid because it prevents the breakdown of pepsinogen to pepsin: the latter irritates tissue to cause peptic ulcers.
