- When some sugars dissolve in water they spontaneously undergo changes in optical rotation called mutarrotation. The Mutarrotation of D-glucopyranose is catalyzed by acid and bases. 2-Hydroxypyridine is a more effective catalyst than phenol and pyridine for this reaction because: a.Both oxygen and N in 2-hydroxypyridine act as bases increasing the rapid interconversion of sugar b. The OH of 2-hydroxypyridine serves as the base while the current N as the acid. c. 2-hydroxypyridine acts both as a base to remove the proton from the hydroxyl group in the hemiacetal and as an acid to provide a proton to the oxygen in the hemiacetal. d.Phenol and pyridine are very expensive.J 5 With pKa of tyrosine's side-chain is 10.1, pKa of its single-strand RNA virus oxidation Carbohydrate glycoside bond Glucose Those double bonds are at ω position of the αcarboxyl and α-amine are 2.2 and 9.1 perspectively. Calculate isoelectric point of tyrosine. i want answer with in one hourPolyunsaturated fatty acids (PUFA's) in oils 0.g. sunflower oil are prone to rancidity because they contain conjugated double bond systems which are easily oxidized in the presence of light or peroxides. BHT Is used as an antioxidant in oils to prevent oxidative rancidity. How do BHT prevent oils from reacting with peroxides so that they do not become rancid? Show the mechanism.

When hydrolyzed by aqueous acid or the enzyme maltase, it forms only d-glucose. When it is treated with excess methyl iodide in the presence of Ag2O and then hydrolyzed with water under acidic conditions, only 2,3,4,6-tetra-O-methyl-d-glucose is formed. Draw the structure of trehalose

Draw the furanose structure of the product.When a pyranose is in the chair conformation in which the CH2OH group and the C-1 OH group are both in axial positions, the two groups can react toform an acetal. This is called the anhydro form of the sugar (it has “lost water”). The anhydro form of d-idose is shown here. Explain why about 80% of d-idose exists in the anhydro form in an aqueous solution at 100 °C, but only about 0.1% of d-glucose exists in the anhydro form under the same conditions.Write down the reactions: D-Glucose + [Ag(NH3)2]+ →
