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.
The original publication concerns the conversion of bile acid in a series of reactions: acid chloride (2) formation with thionyl chloride, diazoketone formation (3) with diazomethane, chloromethyl ketone formation (4) with hydrochloric acid, organic reduction of chlorine to methylketone (5), ketone halogenation to 6, elimination reaction with ...
In glycolysis, a six-carbon glucose molecule is split into two three-carbon molecules called pyruvate. These carbon molecules are oxidized into NADH and ATP. For the glucose molecule to oxidize into pyruvate, an input of ATP molecules is required. This is known as the investment phase, in which a total of two ATP molecules are consumed.
A single glucose molecule is cleaved from a branch of glycogen, and is transformed into glucose-1-phosphate during this process. [1] This molecule can then be converted to glucose-6-phosphate, an intermediate in the glycolysis pathway. [1] Glucose-6-phosphate can then progress through glycolysis. [1]
Carbohydrate synthesis is a sub-field of organic chemistry concerned with generating complex carbohydrate structures from simple units (monosaccharides). The generation of carbohydrate structures usually involves linking monosaccharides or oligosaccharides through glycosidic bonds, a process called glycosylation.
EC 3.2: sugars (DNA glycosylases, glycoside hydrolase) EC 3.3: ether bonds; EC 3.4: peptide bonds (Proteases/peptidases) EC 3.5: carbon-nitrogen bonds, other than peptide bonds; EC 3.6 acid anhydrides (acid anhydride hydrolases, including helicases and GTPase) EC 3.7 carbon-carbon bonds; EC 3.8 halide bonds; EC 3.9: phosphorus-nitrogen bonds
A database may be consulted at each stage of the analysis, to determine whether a component already exists in the literature. In that case, no further exploration of that compound would be required. If that compound exists, it can be a jumping point for further steps developed to reach a synthesis.
