Even though their molecular formulas are the same? Fructose is an isomer of glucose and they are both cyclic and have 5 carbons so I was wondering why fructose was higher on the TLC plate than glucose.
Thank you.
We're given a juice sample and we use thin layer chromatography to identify the sugars in there. They gave us the concentrations of the standard sugar solutions and we were asked to find the μg of glucose (the reducing sugar) in each of the standards. They said to refer to the glucose...

This is for an experiment that separates sugars in a sample using TLC.
We are given a glucose standard solution with a concentration of 1mg/ml as well as 3 standard sugar solutions (glucose, fructose and maltose) all with the same concentration (10mg/ml) in 10% v/v...

I don't understand what E = nhv means. What does it apply to and what does the n (energy level) mean in the equation.
It says in the textbook, "According to Planck, the atoms of the solid osscillate with a definite frequency depending on the solid. But in order to...
They simplified the form of the quotient rule, so I wasn't sure why the whole thing was over the denominator to the power of 3 instead of the power of 4.
When I did the quotient rule again, I understood where I went wrong and how they simplified it, so I have the answer now. Thanks.

Homework Statement
If f(x) can be differentiated, find expressions for the derivatives of the following functions.
a) g(x) = f(x6)
b) h(x) = [ f(x)]6
c) f(x) = x2/ f(x)
The Attempt at a Solution
a)
b) Use the product rule first then multiply that expression by the expression for...
Oh, because I thought the denominator resembled a function in a function, so I thought I could use the chain rule.
But if I did, that would be like taking the derivative of the derivative, right?
Homework Statement
h(x) = (x2 + 3) / (2x - 1)
And if f = the numerator
And if g = the denominator,
h'(x) = (f/g)'
= [ (x2)' + 3' ) * (2x - 1) ] - [ ((2x)' - 1')) * (x2 + 3) ] ALL DIVIDED BY (2x - 1)2
= [2x (2x - 1) - 2 (x2 + 3) ] ALL DIVIDED BY (2x - 1)2
Would I then use the...

You're simply given f(x)/g(x) and it asks, when is the function continuous?
There was one that was definitely wrong, so I remember these remaining choices:
a) It is continuous when f(x) and g(x) are defined
b) " " when g(x) cannot equal 0
c) " " when g(x) is defined...

I was wondering why bonds are more stable at cooler temperatures than at higher temperatures.
This question came from a research project about annealing (heating then colling) plastics and why polyethylene maintains its shape when it's cooled.

How does a large DNA molecule enclosed in the nucleus of a cell?
The Attempt at a Solution
I know it has to do with histones and how DNA winds twice around it to make it shorter, but can anyone further expand on this?
Thanks : )
