核苷酸

核苷酸单体的结构。该核苷酸包含:(一)5碳糖脱氧核糖,(二)含氮碱称为腺嘌呤,(三)和一个磷酸基。总之,脱氧核糖和腺嘌呤组成一个叫做脱氧核苷,(具体地,一个脱氧核糖核苷)。与一个磷酸基团包括,整个结构被认为是一种脱氧核糖核苷酸(DNA的碱基组成)一个名为脱氧腺苷单磷酸。
核苷酸的结构。常见的核酸成分的结构元素。因为它们包含至少一个磷酸基团,该化合物标记为单磷酸核苷,二磷酸核苷和三磷酸核苷全都是核苷酸(不是简单磷酸盐缺乏核苷)。

核苷酸(英语:Nucleotide)为核酸的基本组成单位。核苷酸由含氮碱基,五碳糖和磷酸基团组成。五碳糖为脱氧核糖称为脱氧核苷酸,五碳糖为核糖的称为核糖核苷酸。含氮碱基有五种,分别是腺嘌呤、鸟嘌呤、胞嘧啶、胸腺嘧啶和尿嘧啶。

根据构成核酸的核苷酸数量分为寡核苷酸(少于或等于15个核苷酸)和多核苷酸(15个核苷酸以上)。

英语百科

Nucleotide 核苷酸

This nucleotide  contains the five-carbon sugar deoxyribose, a nitrogenous base called adenine, and one phosphate group. Together, the deoxyribose and adenine make up a nucleoside (specifically, a deoxyribonucleoside) called deoxyadenosine. With the one phosphate group included, whole structure is considered a deoxyribonucleotide (a nucleotide constituent of DNA) with the name deoxyadenosine monophosphate.
The structure of nucleotide monomers.
Structural elements of common nucleic acid constituents. Because they contain at least one phosphate group, the compounds marked nucleoside monophosphate, nucleoside diphosphate and nucleoside triphosphate are all nucleotides (not simply phosphate-lacking nucleosides).
The synthesis of UMP.The color scheme is as follows: enzymes, coenzymes, substrate names, inorganic molecules

Nucleotides are organic molecules that serve as the monomers, or subunits, of nucleic acids like DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). The building blocks of nucleic acids, nucleotides are composed of a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group. Thus a nucleoside plus a phosphate group yields a nucleotide.
