In biochemistry, lipase (/ ˈ l aɪ p eɪ s, ˈ l aɪ p eɪ z / LY-payss, LY-payz) refers to a class of enzymes that catalyzes the hydrolysis of fats. Some lipases display broad substrate scope including esters of cholesterol , phospholipids , and of lipid-soluble vitamins [ 1 ] [ 2 ] and sphingomyelinases ; [ 3 ] however, these are usually ...
The main function of patatin is as a storage protein but it also has lipase activity and can cleave fatty acids from membrane lipids. [2] [3] The patatin protein makes up about 40% of the soluble protein in potato tubers. [4] Members of this protein family have also been found in animals.
Rennet (/ ˈ r ɛ n ɪ t /) is a complex set of enzymes produced in the stomachs of ruminant mammals. Chymosin, its key component, is a protease enzyme that curdles the casein in milk. In addition to chymosin, rennet contains other enzymes, such as pepsin and a lipase.
Pancreatic lipase, also known as pancreatic triacylglycerol lipase or steapsin, is an enzyme secreted from the pancreas.As the primary lipase enzyme that hydrolyzes (breaks down) dietary fat molecules in the human digestive system, it is one of the main digestive enzymes, converting triglyceride substrates like 1 found in ingested oils to monoglycerides 3 and free fatty acids 2a and 2b.
Pancreatic secretion is an aqueous solution of bicarbonate originating from the duct cells and enzymes originating from the acinar cells. The bicarbonate assists in neutralising the low pH of the chyme coming from the stomach, while the enzymes assist in the breakdown of the proteins, lipids and carbohydrates for further processing and ...
Saliva contains the digestive enzymes amylase, and lingual lipase, secreted by the salivary and serous glands on the tongue. Chewing, in which the food is mixed with saliva, begins the mechanical process of digestion. This produces a bolus which is swallowed down the esophagus to enter the stomach.
Nattokinase (pronounced nuh-TOH-kin-ayss) is an enzyme extracted and purified from a Japanese food called nattō.Nattō is produced by fermentation by adding the bacterium Bacillus subtilis var natto, which also produces the enzyme, to boiled soybeans.
Olestra was approved by the Food and Drug Administration for use as a food additive in 1996 and was initially used in potato chips under the WOW brand by Frito Lay.In 1998, the first year olestra products were marketed nationally after the FDA's Food Advisory Committee confirmed a judgment it made two years earlier, sales were over $400 million.
