what is sugar moiety
Moiety is a term that means a part or a portion. So sugar moiety means the sugar molecule in a compound (sugar portion of a complex molecule like nucleic acid). For example when we say that in DNA molecules, the sugar moiety is β-D-2-deoxyribose, it means that the sugar molecule is β-D-2-deoxyribose and describes the position of specific groups on the sugar molecule. Nucleic acids contain sugar molecules.
