Question

There is parts to this one but I will list the question below.

Answer 1

@Somy the question is....
Part A - From a molecular point of view, explain the cliché “water and oil just doesn’t mix.”
Part B - If a chemistry student is given a molecular formula of a molecule, can he or she readily identify it as one compound? Justify your answer.
Part C - Discuss the importance of knowing both the molecular and structural formulas of carbohydrates.
Part D - Discuss the advantages of polysaccharides as it relates to its form and function.

Answer 2

Part A water and oil do not mix because oil has hydrophobic and hydrophilic regions, also water is polar so
hydrophilic is the part that faces water and hydrophobic is the part that is from inside i mean hydrophilic part basically surrounds hydrophobic part thats why as u look at oil in water u'll see a kind of round shape oil and thats all because of these hydrophobic and hydrophilic regions

Answer 3

Part C its because there are compounds like alpha glucose and beta glucose, these two have same Molecular formula BUT different structural formula. SO of course its important to know structural formula as well

Answer 5

if u look at the structure, they both look same but OH in alpha is below and in beta its above

Answer 6

basically saying we need to know molecular and structural because they are Isomers :)

Answer 7

Part D well i think the big advantage is that its insoluble in water so acts as a storage :) in structural level its because they have a lot of amylose (1-4 glycosidic bond) and amylopectin (1-4 and 1-6 glycosidic bonds)

Answer 8

B part i don't really get

Answer 9

thank you so so so so much. I was having so much trouble and couldn't understand half of this. I should be able to figure out part b with the information you gave me. THANK YOU!

Answer 10

you are welcome :D @RainingOranges
