Some hard questions

[JoeG]

I would like to know the answers for some really difficult extra credit problems

 

Whats the difference between Glucose Fructose and Galactose and how does ribose and deoxyribose compare to them

 

What Makes Surose Lactose and Maltose Unique from each other ?

 

Why is cellulose used for structural strength and starch is not ?

 

Why are unsaturated fatty acids are mostly liquid at room temperature

 

What Nucleoties are unstable molecules which carry energy from place to place in the cell and how the unstable molecules work.

 

 

Thank you

Similiar elements used in all of them, the difference is the amount and how they are arranged. Just do google searches to find out the exact structures.

Same as above

 

Why is cellulose used for structural strength and starch is not ?

 

Starch is better used for storing energy then providing structure. Looking at the chemical structure should make that fairly obvious.

 

Why are unsaturated fatty acids are mostly liquid at room temperature

 

I believe there is a thread of SFN that answers this question already... use the search function

 

Thank you

 

Same as your other thread, if these questions are for homework, state it directly.
