Step by step solution

01

Pyranose

Pyranose is a hexagonal ring having five carbons and one oxygen atom in a ring.The only difference between alpha (伪)and beta (尾) anomers is the OH group at C1 carbon. 伪means downward OH and尾 means upward OH.

02

3-D representation with a chair pyranose of a

The OH group at the C5 carbon is on the right side, which is D sugar. The group will come in an upward position. The 伪and尾anomers of part (a) are shown as,

Pyranose anomers of aldohexose a

03

3-D representation with a chair pyranose of b

It is a D-sugar because the OH at C5 is on the right side. So, group will come in the upward position. The 伪and尾anomers in part (b) is shown as,

Pyranose anomers of aldohexose b

Most popular questions from this chapter

Cellobiose, a disaccharide obtained by the hydrolysis of cellulose, is composed of two glucose units joined together in a 1鈫�4-尾- glycoside bond. What is the structure of cellobiose?

a. Identify the glycosidic linkage in disaccharide C, classify the glycosidic bond as 伪or尾, and use numbers to designate its location.

b. Identify the lettered compounds in the following reaction.

As we have seen in Chapter 28, monosaccharides can be drawn in a variety of ways, and in truth, often a mixture of cyclic compounds is present in a solution. Identify each monosaccharide, including its proper D, L designation, draw in a less-than-typical fashion.

(a.)

(b.)

(c.)

(d.)

(a) Draw the more stable chair form of fucose, an essential monosaccharide needed in the diet and a component of carbohydrates on mammalian and plant cell surfaces. (b) Classify fucose as a D- or L-monosaccharide. (c) What two structural features are unusual in fucose?

(a) Why can鈥檛 two purine bases (A and G) form a base pair and hydrogen bond to each other on two strands of DNA in the double helix? (b) Why is hydrogen bonding between guanine and cytosine more favorable than hydrogen bonding between guanine and thymine?
