- A proteose is any of various water-soluble compounds that are produced during in-vitro or in-vivo hydrolytic breakdown of proteins a little before producing amino acids. It forms after breaking down of polypeptides by proteases such as gastric pepsin. In addition to proteoses, peptones are also formed at this stage. The difference between peptones and proteoses is that proteoses are precipitated from solution by half saturation with ammonium sulfate, while peptones don't react even with fully saturated ammonium sulfate. The proenzyme Pepsinogen, with the exposure to hydrochloric acid gets converted into the active enzyme pepsin, the proteolytic enzyme of the stomach. Hydrochloric acid (HCl) provides the acidic pH (pH 1.8) optimal for pepsins. Rennin is a proteolytic enzyme found in gastric juice of infants which helps in the digestion of milk proteins. (en)
- 䏡（Proteose，也译作朊间质，朐）是一种有机化合物，是一種在中的當中，由水解酶—特别是胃蛋白酶—作用于蛋白质而形成的一种，是食物蛋白和的中间产物。䏡溶于水，遇热不凝固。 利用硫酸铵的半飽和溶液，我們可以把一次䏡沉澱出來；利用飽和溶液，則可把二次䏡沉澱出來。[1] (zh)
