Answers to Hard Questions for Ridiculously Difficult Extra Credit

[Swede98]

I would like to know the answers for these questions for my ridiculously hard extra credit.
I have researched these questions and found little information and I really don't know what else to do (I need these points bad)
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

Those are fairly easy questions man. Use http://en.wikipedia.org/wiki/Main_Page, or a biology textbook.

for your interest in these questions. I understand the desire for extra credit and the challenge of finding answers to difficult questions.

To start, let's address the first question about the differences between glucose, fructose, and galactose. These are all monosaccharides, or simple sugars, that have the same chemical formula (C6H12O6) but differ in their molecular structures. Glucose and galactose are both hexose sugars, meaning they have six carbon atoms, while fructose is a ketohexose, meaning it has a ketone functional group in its structure. This small difference in structure leads to different properties and functions in the body. For example, glucose is the primary source of energy for cells, while galactose is primarily used in the production of lactose, a disaccharide found in milk. Fructose is often found in fruits and is sweeter than glucose, making it a common ingredient in sweeteners.

Moving on to the comparison of ribose and deoxyribose, these are both pentose sugars, meaning they have five carbon atoms. The main difference between them is that ribose has an additional hydroxyl group (-OH) on its second carbon, while deoxyribose has a hydrogen atom (-H) in its place. This small difference is crucial in the formation of nucleic acids, as deoxyribose is a key component of DNA while ribose is a key component of RNA.

As for the uniqueness of sucrose, lactose, and maltose, these are all disaccharides composed of two monosaccharide units. The main difference between them is the types of monosaccharides they are made of. Sucrose is made of glucose and fructose, lactose is made of glucose and galactose, and maltose is made of two glucose molecules. This difference in composition leads to different properties and functions in the body. For example, lactose is commonly found in milk and is broken down by the enzyme lactase, while sucrose and maltose are commonly found in fruits and grains, respectively.

Now, why is cellulose used for structural strength while starch is not? This is because of the different ways these two polysaccharides are formed. Cellulose is made of long chains of glucose molecules that are tightly bonded together, creating a strong and rigid structure. Starch, on the other hand, is made of
