nucleoside

 [noo´kle-o-sīd]
any of a class of compounds produced by hydrolysis of nucleotides, consisting of a sugar (a pentose or a hexose) and a purine or pyrimidine base.

nu·cle·o·side (Nuc, N),

(nū'klē-ō-sīd'),
A compound of a sugar (usually ribose or deoxyribose) with a purine or pyrimidine base by way of an N-glycosyl link.

nucleoside

/nu·cleo·side/ (noo´kle-o-sīd″) one of the compounds into which a nucleotide is split by the action of nucleotidase or by chemical means; it consists of a sugar (a pentose) with a purine or pyrimidine base.

nucleoside

(no͞o′klē-ə-sīd′, nyo͞o′-)
n.
Any of various compounds, such as adenosine or guanosine, that consist of a sugar, usually ribose or deoxyribose, linked to a purine or pyrimidine base. Nucleosides are constituents of the nucleotides that make up nucleic acids.

nucleoside

[no̅o̅′klē·əsīd′]
a component of a nucleotide that consists of a nitrogenous base linked to a pentose sugar.

nu·cle·o·side

(nū'klē-ō-sīd)
A compound of a sugar (usually ribose or deoxyribose) with a purine or pyrimidine base.

nucleoside

A molecule compounded of a purine or pyrimidine base attached to a sugar (ribose or deoxyribose). The genetic code in DNA and RNA depends on the order of the nucleosides. A nucleoside is a NUCLEOTIDE without the phosphate group.

nucleoside

a chemical compound in which a nitrogenous base is attached to a sugar. Such a structure occurs in DNA nucleotides where a phosphate group is attached to the deoxyribose sugar of the nucleoside.

nu·cle·o·side

(nū'klē-ō-sīd)
A compound of a sugar (usually ribose or deoxyribose) with a purine or pyrimidine base.

nucleoside (noo´klēəsīd´),

n purine or pyrimidine bases attached to a ribose or deoxyribose.

nucleoside

any of a class of compounds produced by hydrolysis of nucleotides, consisting of a sugar (a pentose or a hexose) and a purine or pyrimidine base.
