At equilibrium in solution, D-glucose consists of a mixture of its anomers. Which statement most accurately describes the solution? A) consists of approximately equal amounts of the a- and B-anomers B) the a-anomer is more stable and is slightly preferred over the B-anomer C) the B-anomer predominates over the a-anomer by a ratio of approximately 2:1 D) straight-chain form is present in high concentration E) none of the above Glucose and galactose are_ A) epimers B) enantiomers C) diastereomers D) anomers E) none of the above of each other. Any sugar that has a free aldehyde group is called a(n) A) reducing sugar B) non-reducing sugar C) ketose D) aldohexose E) alditol
Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
