The concept used to solve this problem is to draw the Fischer projection of glucose. Draw the straight chain and place the –OH group at appropriate positions using the configuration (D or L).
The letters D and L are used for labelling the monosaccharide. D is dextrorotatory and L is levorotatory.
In the Fischer projection, if the –OH group on the bottom stereogenic center is placed on right side, then it is known as D-sugar.
Similarly, if the –OH group on the bottom stereogenic center is placed on left side, then it is known as L-sugar.
The Fischer projection is as follows:
The structure of glucose is as follows:
The Fischer projection is as follows:

Reactions of Monosaccharides Aldose monosaccharides can be oxidized when treated with a mild oxidizing agent. In this reaction, the aldehyde group of the open-chain aldose is oxidized to a carboxylic acid group In basic solution, ketose monosaccharides can also be oxidized. forming carboxylic acids because they can undergo a rearrangement to an aldose form. Monosaccharides (cyclic hemiacetals) can also react with an alcohol to form acetals, called glycosides, and water. In this reaction, the -OH of the anomeric carbon ic...

To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14.

Part B What are the differences between the adrenal hormone cortisone and the synthetic corticoid prednisone? Check all that apply. They have different nuclei. Cortisone has three ketone groups, but prednisone has two. Cortisone has two methyl groups, but prednisone has three. Cortisone has two hydroxyl groups, but prednisone has only one hydroxyl group. Prednisone has a second double bond on the first ring. Submit Previous Answers Request Answer X Incorrect; Try Again; 2 attempts remaining Review | Constants 1...
