OH 10 This is the structure of selenocysteine How is this am

OH 10 This is the structure of selenocysteine. How is this amino acid classified based on its functional group associated with selenium? a. hydrophobic, non-polar d. hydrophilic basic b. hydrophobic polar e. hydrophilic polar c. hydrophilic acidic 11. Which statement about anomers is false? a. For reducing sugars, anomerization is referred to as mutarotation and occurs readily in solution and is catalyzed by acid and base b. The anomeric centre i anomeric carbon C-2. c. In hemiketals it is the carbon derived from the carbonyl of the ketone (e.g. C-2 in D-fructose). d. Two anomers are designated alpha (a) or beta (P), according to the configurational relationship between the in hemiacetals is the anomeric centre and the anomeric reference atom e. In aldohexoses the anomeric reference atom is the stereocenter that is farthest from anomeric carbon in the ring (the configurational atom, defining the sugar as D or L). HO OH OH OH 12. Identify this molecule a. beta-fructofuranose d. alpha- glucopyranose b. alpha- glucopyranose e. alpha-fructofuranose c. beta-glucopyranose 13. What is the condition when glucose levels become too high? b. hyperglycemia e. ketoacidosis a. hypoglycemia d. hypotonic c. hypertonic

Solution

10)

Amino acid classified based on its functional group associated with selenium is:

Option c) hydrophilic polar  because they usually participate in hydrogen bonds as proton donors or acceptors.

11)

a) ALL OF THE ABOVE STATEMENTS ARE TRUE

12)

The molecule is:

Option c beta glucopyranose

13

When glucose levels are too high

option b (hyperglycemia)
