An enzyme that catalyzes the coagulation of milk, obtained from the fourth stomach of calves and other young ruminants or from genetically engineered microorganisms and used in making cheeses and junkets. Also called chymosin.


(Biochemistry) an enzyme that occurs in gastric juice and is a constituent of rennet. It coagulates milk by converting caseinogen to casein. Also called: chymosin
[C20: from rennet + -in]


(ˈrɛn ɪn)

a coagulating enzyme occurring in the gastric juice of the calf, forming the active principle of rennet and able to curdle milk.
[1895–1900; renn (et) + -in1]

The dietary change was also shown to cause the kidneys to release more of a protein called rennin and its hormone aldosterone, which is linked with high blood pressure.
UF of milk is done to save cost during preparation of semi-hard and hard cheese by increasing the salt and whey protein concentration but it causes compromised sensory and functional properties (Mistry and Maubois, 1993) with slower ripening rate due to decreased proteolysis caused by reduction chymosin and rennin action and presence of more whey proteins (Neocleous et al.
Space constraints limited the amount of information we are able to share at this time The early winter issue of the Colorado Nurse will include a more comprehensive article about Dr Rennin If you were one of those who life and career were influenced by Dr Rennin.
The idea was to clone the enzyme rennin and to get it expressed and secreted from the Bacillus.
RENNET: An extract from the membranes of calves' stomachs that contains rennin, an enzyme that aids in coagulating milk or separating curds from whey.
The hypertensive state of both the SH and SHHF rats has been linked to genetic anomalies in the rennin angiotensin system (Leckie 2001) and the [beta]-adrenergic system (Remmers et al.
The pancreatic juice contains enzymes for digesting proteins (trypsin), carbohydrates (amylopsin), lipids (steapsin), and rennin for coagulating milk.
The reduction was associated with decrease in systemic vascular resistance, plasma norepinephrine, plasma rennin activity, body weight, waist size, per cent body fat and insulin resistance.
East Hanover, NJ, announced the FDA has approved Tekamlo (aliskiren and amlodipine) tablets, a single-pill for the treatment of high blood pressure combining the only approved direct rennin inhibitor, Tekturna (aliskiren), with the widely used calcium channel blocker amlodipine.
Another mechanism is that the posts exercise hypotension which is accompanied by a decrease in serum catecholamine's, norepinephrine, dopamine, cortisol, sympathetic nervous system, plasma rennin activity thus suppresses inflammatory reaction and finally down-regulates WBC count.
