Nepenthesin (and the carnivorous plants it comes from)
Nepenthesin (also spelled nepenthacin or nepenthasin) is an aspartic protease of plant origin that has so far been identified in the pitcher secretions of Nepenthes and in the leaves of Drosera peltata. Discovery In the late 19th century, Sydney Howard Vines showed that the pitcher fluid from Nepenthes could digest protein in acidic conditions. He suggested the plants were making a digestive enzyme, for which he proposed the name “nepenthin”. In…

List of human clusters of differentiation (OR CD) MOLECULES
* = group; ** = not listed on hcdm CD1* MHC-like molecule that presents lipid molecules CD1a CD1a (Cluster of Differentiation 1a), or T-cell surface glycoprotein CD1a, is a human protein encoded by the CD1A gene. An antigen-presenting protein that binds self and non-self lipid and glycolipid antigens and presents them to T-cell receptors on natural killer T-cells. CD1b T-cell surface glycoprotein CD1b. Expressed on cortical thymocytes, certain T-cell leukemias…

Calcitonin
Calcitonin is a 32 amino acid peptide hormone secreted by PARAFOLLICULAR CELLS (also known as C cells) of the thyroid (or endostyle) in humans and other chordates in the ultimopharyngeal body. It acts to reduce blood calcium (Ca2+), opposing the effects of PARATHYROID HORMONE (PTH). Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant in the…

Rennet
For the apple varieties, see Reinette Rennet 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. Rennet has traditionally been used to separate milk into solid curds and liquid whey, used in the production of cheeses. Rennet from calves has become less common for this use, to the…

What Are Plant Matrix Metalloproteinases?
Plant matrix metalloproteinases are metalloproteins and zinc enzymes found in plants. Matrix Metalloproteinase Matrix metalloproteinases (MMPs) are zinc endopeptidases, commonly called metzincins. MMP enzymes represent an ancient family of proteins with major similarities in genetic make-up that are present in a range of diverse organisms from unicellular bacteria to multicellular vertebrates and invertebrates. The superfamily is distinguished due to its motif consisting of three histidines bonded to…

What Is Carnoy’s Solution?
Carnoy’s solution is a fixative composed of 60% ethanol, 30% chloroform and 10% glacial acetic acid, 1 gram of ferric chloride.[1][2] Carnoy’s solution is also the name of a different fixation composed of ethanol and glacial acetic acid (3:1).[3][4][5] Hm..and here are some articles that come up on a search for Carnoy’s solution at Science Direct I haven’t read them all but this…

What Is Nitrophenol? (besides something mentioned in ‘Scientific Opinion on the re‐evaluation of aspartame as a food additive’)
Nitrophenols are compounds of the formula HOC6H5−x(NO2)x. The conjugate bases are called nitrophenolates. Nitrophenols are more acidic than phenol itself. Wikipedia Mono-nitrophenols with the formula HOC6H4NO2. Three isomeric nitrophenols exist: o-Nitrophenol (2-nitrophenol; OH and NO2 groups are neighboring; CAS number: 88-75-5), a yellow crystalline solid (m.p. 46 °C). m-Nitrophenol (3-nitrophenol, CAS number: 554-84-7), a yellow solid (m.p. 97 °C) and precursor to the…

Another reason not to feed pigeons – your food is poison?
I can’t tell you why except they showed up on a wiki search. Climate change has a negative effect on this bird, and reproductive performance decreases with increased temperatures. It is also particularly vulnerable to oil, and adults near oiled shores display symptoms of hepatocellular injury, where elevated levels of aspartate aminotransferase can be found in the liver. Otherwise,…
