Draw the structures of the TWO glycoside products formed below.4.3.1.ноHOноноHO0-HO.OCH3OHонНоноa OCH,HOHÓноHOOCH3CH2OCH34. Which molecule(s) represent(s) (a) NON-REDUCING SUGAR(S)?Onchair conformationFischer

Here molecule 3 represents Non- Reducing sugar since it lacks a hemiacetal group and has a acetal group in it's structure, so it's structure cannot be opened and it cannot donate a hydrogen for reduction of the other compound. So, 3 is a non-reducing sugar.1,2 and 4 molecule have a hemiacetal group available which can donate hydrogen for reducing the other compound, so they are reducing sugars.

3. Proteins are important for numerous functions in a cell and their activity/function is dependent on their structure. Each protein folds into its respective structure and ionic bonds between ions in side chains of proteins drives protein folding as shown by the oppositely charged ions in the figure below. 15 H .O H N Protein Draw a picture similar to the one shown above to show what will happen to such interactions when the pH increases. Show how this impacts protein structure. (Hint: Is the hydrogen ion concentration high or low? Note that hydrogen ions can be added or lost into molecules depending on the pH and that the NH3* is affected in this case.)
