How long would it take to get 1 micro gram of glucose if sucrose decomposed at a rate of 1 million molecules per second?
Let's start by setting up an equation of what is going on chemically. Sucrose
is a sugar dimer of 1 fructose and 1 glucose molecule, so:
1 Sucrose --> 1 Glucose + 1 Fructose
So, what we need to do from here is calculate how many moles of glucose would
be needed to make 1 microgram (ug). The Atomic Mass of glucose is 180.16 g/mol,
so 1ug = .000001 g. 0.000001g divided by 180.16 g/mol = 5.55 X 10^9 moles.
Avogadro's number is 6.02214 X 10^23 and represents how many molecules are in 1
mole of a substance. Multiply this number by the moles of glucose and we should
get 3.34 X 10^15 molecules in 1 microgram of glucose.
Since the decomposition of 1 molecule of sucrose liberates 1 molecule of glucose,
we do not have to take into account stoichiometric ratios.
So, we need 3.34X 10^15 molecules of sucrose to decompose to get the same
number of molecules of glucose. If we divide this by 1 million, we get
3.34 x 10^9. This is the number of seconds that would be needed for the
decomposition to take place. Divide that by 60 we get 5.57 X 10^7 minutes,
divide by 60 again and we get 9.28 X 10^5 hours, divide by 24 and we get 38,684
days and finally divide by 365 to get just under 106 years!
What else can I help you with?
What chemical change can you make in sugar?
Sucrose can be decomposed in glucose and fructose.
What is the correct order by size of the following molecules water sucrose glucose and protein?
The correct order by size of the molecules listed would be protein > sucrose > glucose > water. Proteins are the largest molecules, followed by sucrose (a disaccharide), glucose (a monosaccharide), and then water.
Is sucrose molecules bigger than glucose molecules?
Yes, sucrose molecules are larger than glucose molecules. Sucrose is a disaccharide composed of one glucose molecule and one fructose molecule, while glucose is a monosaccharide. This difference in structure accounts for the difference in size between the two molecules.
How would you change sucrose formula to two molecules of glucose?
By hydrolysis sucrose is transformed in glucose and fructose.
How do you change sucrose to glucose?
Sucrose is a disaccharide composed of glucose and fructose. A sucrase will hydrolyze sucrose into both constitute parts. You will be left with glucose and fructose, but you cannot directly transform sucrose to glucose.
What two molecules are used to make glucose?
Sucrose and Lactose. Sucrose is made from glucose and fructose, and Lactose is made from glucose and galactose. Hope this helps! (:
Give an example of disaccharides?
Sucrose, lactose, and maltose are examples of disaccharides. Sucrose is made up of glucose and fructose, lactose is composed of glucose and galactose, and maltose consists of two glucose molecules.
What does maltase break down?
two glucose molecules
Is sucrose a double bond?
Sucrose is a disaccharide comprised of glucose and fructose. While both glucose and fructose have double bonds, sucrose does not.
How do you know that sucrose conatains carbon?
Sucrose is a polymer of glucose. That is, it is a combination of glucose molecules. The chemical formula for glucose is C6H12O6 [6 Carbons, 12 Hydrogens, and 6 Oxygens], so since sucrose is made of glucose, it must contain Carbon.
What kind of molecules formed when glucose and fructose are combined?
Sucrose. Disaccharide
How do you list these molecules from smallest to largest NaCl Sucrose Water Glucose Starch?
From smallest to largest: NaCl, Water, Glucose, Sucrose, Starch. They are ordered based on their molecular weight and size.
