Rennin | Curdling Milk, Cheese Making, Proteolysis | Britannica
2024年11月28日 · rennin, protein-digesting enzyme that curdles milk by transforming caseinogen into insoluble casein; it is found only in the fourth stomach of cud-chewing animals, such as cows. Its action extends the period in which milk is retained in the stomach of the young animal.
Chymosin - Wikipedia
It is an aspartic endopeptidase belonging to MEROPS A1 family. It is produced by newborn ruminant animals in the lining of the abomasum to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption. It is widely used in the production of cheese.
凝乳酶 - 维基百科，自由的百科全书
凝乳酶（英语：Chymosin或Rennin）是一种在皱胃酶中发现的蛋白酶。它是属于MEROPS A1家族的天冬氨酸蛋白酶。它是由新生反刍动物在皱胃内壁产生的，用于凝结它们摄入的乳汁，从而在肠道中停留更长时间并更好地吸收。它广泛用于奶酪的生产。
Renin - Wikipedia
Renin is secreted from juxtaglomerular kidney cells, which sense changes in renal perfusion pressure, via stretch receptors in the vascular walls. The juxtaglomerular cells are also stimulated to release renin by signaling from the macula densa.
肾素 - 百度百科
肾素（Renin），也被称为血管紧张素原酶，是肾小球旁器（也称球旁复合体）的球旁颗粒细胞释放的一种蛋白水解酶，是肾素-血管紧张素系统的组成部分。 肾素最早于1898年由瑞典斯德哥尔摩卡罗琳学院生理学教授RobertTigerstedt发现、描述并命名。 肾素为肾小球旁细胞所分泌，其分泌量受肾小动脉压及流经致密斑原尿中的钠量等因素所影响。
Chymosin (Rennin) and the Coagulation of Milk - Colorado State …
Chymosin, known also as rennin, is a proteolytic enzyme related to pepsin that synthesized by chief cells in the stomach of some animals. Its role in digestion is to curdle or coagulate milk in the stomach, a process of considerable importance in the very young animal.
Rennin - Oxford Reference
3 天之前 · Rennin converts caseinogen (milk protein) into insoluble casein in the presence of calcium ions. This ensures that the milk remains in the stomach, exposed to protein-digesting enzymes, for as long as possible. The largest amounts of rennin are present in the stomachs of young mammals.
Rennin (Enzyme) - Biology Wise
Rennin, which is an active enzyme in rennet (a complex of enzymes present in any mammalian stomach), masks kappa-casein so that the other three molecules get precipitated. Chymosin is present in its inactive form prorennin at the time of birth. It …
