What is the difference between the D-form and the L-form of a compound?
The stereochemistry. Specifically, for carbohydrates, the configuration at the last (highest numbered) stereocenter determines whether it's D or L form. D means it has the same configuration as (+)-glyceraldehyde; L means it has the same configuration as (-)-glyceraldehyde. Note that D and L (capital letters) are not at all the same as d and l (lower letters). The capital letters relate the configuration to glyceraldehyde, the lower case letters specify whether the substance is dextrorotatory or levorotatory. For glyceraldehyde, D is d (+) and L is l (-), but this is not always the case for other molecules.
How does the L-glyceraldehyde differ from the D-glyceraldehyde?
D and L are easily determined by looking at the hydroxy group that is farthest away from the aldehyde group. If it is on the right, it is the D enantiomer. If it is on the left, it is the L enantiomer. Each enantiomer will rotate plane polarized light in opposite directions. This can be determined using a polarimeter.
What are an aldose ketose pair?
example Dihydroxyacetone (ketone) and D-glyceraldehyde ( aldoste)
What is the function of aldolase in regulation of glycolysis?
Aldolase inhibits the reaction F-1-P --> glyceraldehyde + dihydroxyacetone.
Difference between D L Sugars?
D and L are optical isomer of each other, or non superimposible mirror images. The convention uses Glyceraldhyde as the reference. In a fisher projection the OH of glyceraldehyde is on the right side ( more improtantly in the R configuration)in the D isomer and on the left side ( or the molecule is in the L configuration) in the L isomer. So for all other sugars it looks at the last chiral center for the molecule if the chiral center is R it is a D isomer if the last chiral center is in the S configuration it is an L isomer.
Why is d glucose dextrorotatory but d fructose is levorotatory?
I think you mean D-fructose is leavorotatory. D is a convention that compares a steroisomer to glyceraldehyde and does not define the right/left roatoion of plane polarised light.

What is the full form of D and L in D and L configuration?
That IS the "full form". They stand for "dextrorotatory" and "levorotatory" respectively, but it should be noted that these terms (which have to do with whether the compound rotates polarized light to the right or the left) do not actually apply to the compounds themselves... rather, it refers to the enantiomer of glyceraldehyde that they are related to. Saying "dextrorotatory" instead of D would imply that the compound itself is (+) ... that is, it rotates light to the right ... which may or may not be the case. D-glyceraldehyde itself actually IS (+), but it turns out that that was a lucky guess... the nomenclature had been established before anyone really knew for certain that they'd assigned the names to the proper structure. To give a simple example: the L-amino acids commonly found in proteins are divided just about equally in terms of which direction they rotate light: 9 are (+) and 10 are (-). Calling them "levorotatory" would imply they're all (-), which is definitely not the case.
