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.

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.

What is the electron configuration of calcium in terms of s p and d orbitals?
Beryllium is located in group 2 of the periodic table and has a valency of two. It is an element in the 2nd period and has two main energy levels. Therefore the electron configuration is 1s2 2s2.

What do you understand by D and L forms of mono saccharides?
D and L forms of monosaccharides refer to the configuration of the highest-numbered chiral carbon in a sugar molecule. In the D form, the hydroxyl group on the highest-numbered chiral carbon is on the right side, while in the L form, it is on the left side. The designation of D or L does not indicate the direction of optical rotation.
What is the difference between D configuration and L configuration sugars?
The behavior against polarized light is different.
How many isomers of d-ketohexofuranose are possible?
Answer 8 D-isomers of fructose, as I figured out. Of the D-keto-hexoses (like fructose) there are : 8x D-2-ketoses: alpha and beta form of 4 members [D-psicose, D-fructose, D-sorbose, D-tagatose] Not: D-3-ketoses can NOT form furanose ring (4C + O) Not: D-4-ketoses = same as D-3-ketose Not: D-5-ketoses = D-2-ketose At last you can also mention the same set of the (full) enantiomers in L-form: 8x L-2-ketoses: alpha and beta form of [L-psicose, L-fructose, L-sorbose, L-tagatose]
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.
