What is the definition for deoxyribose?
Definition of deoxyribose : a pentose sugar C5H10O4 that is a structural element of DNA.
What is the formula for DNA?
Calculating the sum formula

What is deoxyribose and example?
Definition. (1) An aldopentose (i.e. a monosaccharide with five carbon atoms) derived from the pentose sugar ribose by the replacement of a hydroxyl group with a hydrogen atom at the 2 position, leading to the net loss of an oxygen atom (hence the name).
What is the deoxyribose sugar?
deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases. Deoxyribose was synthesized in 1935, but it was not isolated from DNA until 1954.
What is the formula of adenine?

Adenine/Formula
What’s the difference between deoxyribose and ribose?
The pentose sugar in DNA is called deoxyribose, and in RNA, the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the 2′ carbon of the ribose and its absence on the 2′ carbon of the deoxyribose.
What is DNA explain?
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Where can you find deoxyribose?
DNA contains a string of units called nucleotides, that contain deoxyribose. Nucleotides carry energy throughout cells and play a role in metabolism. Nucleotides contain a phosphate group and a nitrogen-carrying base, in addition to deoxyribose, the building block of DNA.
How is deoxyribose numbered?
The carbon atoms present in the deoxyribose are numbered 1′, 2′, 3′, 4′ and 5′. Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)).
What is the correct formula for Deoxyribose?
Deoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula H−(C=O)−(CH 2)−(CHOH) 3−H. Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of an oxygen atom.
What is the function of deoxyribose sugar?
Lesson Summary. Deoxyribose is a pentose sugar important in the formation of DNA, or deoxyribonucleic acid. Deoxyribose is a key building block of DNA. Its chemical structure allows for the replication of cells in DNA’s double helix configuration.
What is deoxyribose in coffee?
Deoxyribose is a sugar, but not the kind we think about when we want to sweeten our coffee. A monosaccharide is a deoxyribose. Monosaccharides serve as the foundation for more complex sugars. The words ‘mono’ and ‘saccharide’ mean ‘one’ and ‘sugar,’ respectively.
Is deoxyribose a monosaccharide?
Deoxyribose is a monosaccharide. Monosaccharides are the building blocks for more complicated sugars. Here, ‘mono’ means ‘one,’ and ‘saccharide’ means ‘sugar.’ Deoxyribose is also known more precisely as 2-deoxyribose and is a component of DNA. Any molecule that ends in ‘ose’ is considered a sugar.
