Could you explain step by step each answer and how to get there?

Consider these three monosaccharides. H H CH₂OH H- -OH HO H HO H H -OH H OH CH₂OH CH₂OH CH₂OH Part 1 of 3 Which two monosaccharides are stereoisomers? Check two. HO H H OH CH₂OH H -OH H OH CH₂OH CH,OH HO -H снон None of the above Part 2 of 3 Identify two compounds that are constitutional isomers. Check two. CH,OH C=0 Undo HO -H HO H CH,OH H OH CH₂OH H -OH H .OH CH₂OH None of the above Part 3 of 3 Use the Fischer projection carbon drawing tool to draw the enantiomer of this monosaccharide. H H -OH H -OH CH₂OH Click and drag to start drawing a structure.

Test for Monosaccharides:  Clinistix Carbohydrate molecules range from the very simple to the very complex. The word “saccharide” means sugar, while the prefixes “mono”, “di” and “poly” categorize carbohydrates according to how many simple sugar molecules are joined together to form the carbohydrate.   To test for the presence of monosaccharide, we will be using Clinistix (a product that is used to test for the presence of glucose in urine).  See the label (in video) for details.  These test strips are used by dipping the colored end into the solution, then comparing the color to the chart on the bottle.  The positive color(s) is/are __________________________.  The negative color is ________________.   Test for Starch (a Polysaccharide):  Povidone Iodide Test Plant cells manufacture glucose molecules during photosynthesis and store them in large starch molecules.  Because starch is a long chain of many glucose units all joined together, it is a polysaccharide. Povidone Iodide (which…

I. Write a balanced chemical reaction, complete with chemical structures, to show the hydrolysis of iso-C to U. II. Draw the mechanism by which iso-G converts to its "minor tautomeric form complementary to U."  You may propose either an acid or base catalyst. III. Draw chemical structures of the minor tautomeric form of iso-guanine (iso-G) and uracil (U), showing the non-covalent bonding (H-bonding) interactions between them.
