Biomolecules(11th And 12th > Chemistry ) Questions and Answers
Explanation:-
Answer: Option C. -> Cysteine:
C
Option (c)
You can clearly see that cysteine is the only amino acid from the options given which contains a sulphur in its structure. You can remember this by going back to the video of the secondary structure of proteins where we talka about the Disulphide linkages which gives shape to the protein sheets.
Explanation:-
Answer: Option A. -> Cellulose:
A
We cannot digest cellulose, which is a polysaccharide. Our digestive system is not capable of digesting this tough carbohydrate. However, herbivorous animals like cows are well-equipped to do just that.
Explanation:-
Answer: Option B. -> Configuration:
B
Option (b)
It is clear from the above picture that there is no other difference in these 2 structures other than the difference at the C-1 carbon, which can be attributed to the difference in the configuration of the carbon. This carbon is referred to as the anomeric carbon to highlight this important feature.
Explanation:-
Answer: Option B. -> Fructose:
B
Option (b)
Sugar Relative sweetness order-
Sucrose 100
Glucose 74
Lactose 16
Fructose 173
From this, it is clear that Fructose is the sweetest.
You might have guessed it's either Sucrose and Fructose from experience, but between these 2 we will need some proper experimental techniques to determine which is the sweeter one.
