27. Which of the following statements about cholesterol is not correct? CH3 CH3 H. d но Cholesterol (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.

Carbohydrates. Determination of the extent of branching in glycogen. The amount of branching (number of α 1⟶ 6 glycosidic bonds) in glycogen can be determined by the following procedure. A sample of glycogen is exhaustively methylated-treated with a methylating agent (methyl iodide) that replaces the hydrogen of every sugar hydroxyl with a methyl group, converting –OH to –OCH3. All the glycosidic bonds in the treated sample are then hydrolyzed in aqueous acid, and the amounts of α -D-2,3-di-O-methylglucopyranose and α -D-2,3,6-tri-O-methylglucopyranose formed are measured. 1- Draw the cyclic structure of α-D-glucopyranose, α-D-2,3-di-O-methylglucopyranose and α-D-2,3,6-tri-O-methylglucopyranose, including the numbering of carbon atoms. 2- Which of α-D-2,3-di-O-methylglucopyranose or α-D-2,3,6-tri-O-methylglucopyranose represents a glucose unit in glycogen which was originally carrying a α 1⟶ 6 glycosidic bond? Explain.

When a crystalline sample of α-glucopyranose is dissolved in water and the specific rotation is measured immediately, the observed rotation is +112°. When the same amount of βglucopyranose is dissolved, the observed rotation is +18.7°. However, over time, at room temperature, both solutions reach a specific rotation of +52.7°. Explain why these two solutions reach the same specific rotation over time.
