Carbohydrase is the name of a set of enzymes that catalyze five types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. [ 1 ] Carbohydrases are produced in the pancreas , salivary glands and small intestine , breaking down polysaccharides .
Osazone formation was developed by Emil Fischer, [3] who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. [4] Since the reaction requires a free carbonyl group, only "reducing sugars" participate.
3-Amino-1,2,4-triazole (3-AT) is a heterocyclic organic compound that consists of 1,2,4-triazole with an amino group as a substituent. 3-AT is a competitive inhibitor of the product of the HIS3 gene, imidazoleglycerol-phosphate dehydratase. [3] [4] Imidazoleglycerol-phosphate dehydratase is an enzyme catalyzing the sixth step of histidine ...
They are found in raw plants/herbs such as cinnamon and bacteria (containing the inhibitor acarbose). [ 1 ] [ 2 ] Carbohydrates are normally converted into simple sugars ( monosaccharides ) by alpha-glucosidase enzymes present on cells lining the intestine, enabling monosaccharides to be absorbed through the intestine.
Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
The drug is occasionally used on an intermittent basis to prevent seizures in catamenial epilepsy. [10] The sulfur-containing antiseizure and antimigraine drug topiramate is a weak inhibitor of carbonic anhydrase, particularly subtypes II and IV. [11] Whether carbonic anhydrase inhibition contributes to its clinical activity is not known.
Glycoside hydrolases are found in essentially all domains of life. In prokaryotes , they are found both as intracellular and extracellular enzymes that are largely involved in nutrient acquisition. One of the important occurrences of glycoside hydrolases in bacteria is the enzyme beta-galactosidase (LacZ), which is involved in regulation of ...
Its products are 7alpha,12alpha-dihydroxycholest-4-en-3-one, NADP +, and H 2 O. Since 2015, the enzyme has been classified with EC 1.14.14.139 with the systematic name of 5β-cholestan-3α,7α-diol 12α-hydroxylase. Other names that have been used include 7alpha-hydroxycholest-4-en-3-one,NADPH:oxygen oxidoreductase (12alpha-hydroxylating ...
