- Construct the two enantiomeric forms/structure of the following monosaccharides and designate the handedness of each using D, L system: a. RibuloseIndicate which of the terms monosaccharide, disaccharide, reducing sugar, anomers, enantiomers, and aldohexose applies to both members of each of the following pairs of substances. More than one term may apply to a given pair of substances. a-D-Glucose and a-D-galactose- Sucrose and cellobiose- Glyceraldehyde and dihydroxyacetone- D-Ribose and L-ribose-Monosaccharides have the general molecular formula of (CH₂0)m, where m is the number carbons. (m=5 is a pentose, such as xylose & m=6 is a hexose such as glucose.) Starch is a polysaccharide of thousands of glucose monomers, linked by an oxygen (-0-) bridge. The general molecular formula for starch is usually taken as (C6H1005) when n is the degree of polymerization. When formed from glucose a water molecule is released for every step in the polymerization process; when hydrolyzed (de-polymerized) a water molecule is necessary. The de-polymerization reaction can be considered as: (C6H1005)n + α H₂O → B (C6H1206) Balance the stoichiometry, i.e., find expressions for a & ß (that may involve the degree of polymerization, n). If we start with 1 kg of starch & totally hydrolyze it to glucose then how much glucose do we get [in kg & kg.mole]? Do the calculations assuming that n=1,000. The fermentation of glucose to ethanol can be expressed in the figure on the right¹. How much ethanol can be…
