O-Substitution with Alkyl and Acyl Groups
5 Carbohydrates
a-Alkyl and a-acyl derivatives of saccharides can most easily be named
as such even though traditional ester names are still widely used for the
latter.

The inevitable acronym ADP too comes from the ester name adenosine5' -diphosphate customarily preferred to the systematic denominations 5'0-( diphosphonato )adenosine or 5'-( diphospho )adenosine.

Cyclic Acetals and Ketals
Cyclic acetals and ketals produced from saccharides by reactions with
aldehydes and ketones, respectively, are identified as x,y-a-alkyl(id)ene
derivatives.
