Draw the structure and give the systematic name of the given disaccharides. [No need to show the stepwise process] (a) Lactose which is also known as milk sugar: β-D-Gal(1à4)β-D-Glc, where Gal is galactose and Glc is glucose.
Answer the following questions. (I narrowed it down to only three subparts)
Which statement about saccharides is correct? (A). Alpha anomers are more common than beta anoomers. (B). Two monosaccharides can form a disaccharide and oxygen. (C). Polysaccharides with alpha or beta glycosidic linkages have the different properties. (D). Disaccharides can be cyclic or acyclic.
31. Which of the following statements about cholesterol is not correct? CH. HO Cholesterol 16 (a) Cholesterol is a steroid that contains a tetracyclic ring system. (b) Cholesterol is a steroid that contains 8 chiral carbons and can form 28 or 256 stereoisomers. (c) Each atom or group attached to a ring-junction carbon (i.e., carbons a-e) is in a trans or axial position. Because of this the tetracyclic ring system is mostly flat. (d) Cholesterol is used to synthesized vitamin D, bile acids, sex hormones, and adrenocorticoid hormones. (e) Cholesterol is not found in the cell membranes of animals.

(d) Use the diagram below to complete the cyclic alpha form of structure V (e) Circle the hemiacetal in cyclic alpha form of structure V. (f) Redraw the cyclic alpha form of structure V but replace the OH group on the anomericcarbon with a methoxy group. Is this modified monosaccharide a reducing sugar or anonreducing sugar?

9 A disaccharide consists of the molecules of D-glucose and D-glucosamine joined by a (1a, 1b)-glucosidic bond. a) Draw the structure of the disaccharide (Haworth projection) if you know that in D- glucose the anomeric carbon has an a-configuration. b) Give the name of the union you drew in question a. c) Draw the structure of the product (cantilever conformation) resulting from the effect of excess acetic anhydride and pyridine on the disaccharide. Hint: D-glucosamine has the same structure as D-glucose, but C-2 has an amino group instead of a hydroxyl.
using the picture below as reference: do the following: a.) label if any of the structures (A-D) are any of these classes of compounds: - a keto-pentose - an L-monosaccharide - a hexose b.) then draw the Haworth projections of compound A as an α-isomer
