what is the difference between I want to cut out aspartame
out of my diet but I've
noticed that many foods
contain sucrose. Is sucrose a
form of aspartame? Is it just
as bad?

Sucrose (common name: table sugar, also called saccharose) is a disaccharide of glucose and fructose, with the molecular formula C12H22O11. Its systematic name is α-D-glucopyranosyl- (1↔2)-β-D-fructofuranoside (ending in "oside", because it's not a reducing sugar). It is best known for its role in human nutrition and is formed by plants but not by other organisms such as animals. Aspartame (or APM) (pronounced /ˈæspɚteɪm/ or /əˈspɑrteɪm/) is the name for an artificial, non-saccharide sweetener, aspartyl-phenylalanine-1-methy l ester; that is, a methyl ester of the dipeptide of the amino acids aspartic acid and phenylalanine. |

Why is glucose converted into is it something to do with
glucose being a monomer and
sucrose being a disaccharide
consisting of 1 alpha-glucose
and 1 beta-fructose?
please help!
thank you!

Glucose and fructose are the monosaccharides. When you take a molecule of each and take away one water molecule, a H from one and an OH from the other, the resulting disaccharide sucrose is formed. By forming the more complex sugar, the plant is able to store energy more efficiently in a more compact form as the disaccharide. When it requires the monosaccharides for the energy cycle, it hydrolyzes the sucrose back into the glucose and fructose by adding back one molecule of water. |

Why is sucrose metabolized Sucrose and fructose need to
be rearranged into glucose,
but why does this step take
longer with fructose? Or is
there another reason?

In the process of glycolysis, the first sugar to enter it is glucose. The cell will add a phosphate and make it glucose 6 phosphate keeping it from leaving the cell. The next step it is changed into fructose 6 phosphate. Sucrose is a combination of glucose and fructose. The sucrose is digested and the glucose is utilized right away while the fructose needs to be converted to glucose before it can enter the glycolytic pathway. So sucrose yields 50% glucose ready to go and 50% fructose needing to change. All fructose needs to be changed so the reaction is quicker. |
