	Deoxyribose - Wikipedia, the free encyclopedia
		Deoxyribose (more precisely 2-deoxyribose) is an aldopentose — a monosaccharide containing five carbon atoms, and including an aldehyde functional group.
		In deoxyribose, the carbon furthest from the attached carbon is stripped of the oxygen atom in what would be a hydroxyl group in ribose.
		One of the common bases is adenine (a purine derivative), coupled to ribose it is called adenosine, coupled to deoxyribose it is called deoxyadenosine.

	deoxyribose -- Encyclopædia Britannica
		The presence of deoxyribose instead of ribose is one difference between DNA and RNA (ribonucleic acid).
		Deoxyribose was synthesized in 1935, but it was not isolated from DNA until 1954.
		Each chain is made up of units containing the sugar deoxyribose; phosphoric acid; and a nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

	URACIL (2,4-DIHYDROXYPYRIMIDINE)
		Its close relative, deoxyribose, is a constituent of deoxyribonucleic acid (DNA), where it alternates with phosphate groups to form the 'back-bone' of the DNA polymer and binds to nitrogenous bases.
		The sugar (ribose or deoxyribose) molecules in the nucleic acid are all oriented in the same direction.
		Urasil is a pyrimidine base, occurring condensed with ribose or deoxyribose to form the nucleosides uridine and deoxyuridine in animal cells.

	Introduction to DNA Structure (Site not responding. Last check: 2007-10-07)
		The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
		Deoxyribose lacks an hydroxyl group at the 2'-position when compared to ribose, the sugar component of RNA.
		The deoxyribose sugars are joined at both the 3'-hydroxyl and 5'-hydroxyl groups to phosphate groups in ester links, also known as "phosphodiester" bonds.

	DNA Structure
		Deoxyribose refers to the fact that one of the hydroxyl (OH) groups is missing from this sugar.
		Note that the carbons in deoxyribose are numbered 1 through 5.
		Note that the deoxyribose sugar and phosphates are linked together to form a backbone.

		The backbone of the polymer is composed of phosphate groups alternating with a sugar (deoxyribose) to form a covalently linked chain.

		It has been found experimentally (3,4) that the ratio of the amounts of adenine to thymine, and the ration of guanine to cytosine, are always very close to unity for deoxy ribose nucleic acid.
		It is probably impossible to build this structure with a ribose sugar in place of the deoxyribose, as the extra oxygen atom would make too close a van der Waals contact.
		The previously published X-ray data (5,6) on deoxyribose nucleic acid are insufficient for a rigorous test of our structure.

	Carbohydrates - Ribose
		Ribose and its related compound, deoxyribose, are the building blocks of the backbone chains in nucleic acids, better known as DNA and RNA.
		Ribose and deoxyribose are classified as monosaccharides, aldoses, pentoses, and are reducing sugars.
		The presence or absence of the -OH group on carbon (#2) is an important distinction between ribose and deoxyribose.

		D means this five-carbon sugar has the same stereochemical configuration at the Number 4 and 5 carbons as the Number 2 and 3 Carbons of D-glyceraldehyde.
		"3',5' linkages" means that two deoxyribose sugars are connected to a phosphate in the middle by the Number 3 carbon on one sugar and by the Number 5 carbon on the other sugar.

	DNA
		Deoxyribose is made of carbon, hydrogen and oxygen atoms.
		It forms one bond with the 5′ carbon on one deoxyribose and another bond with the 3′ carbon on the next deoxyribose in the chain.
		Because of the way the phosphate binds to the 5′ carbon of one deoxyribose and the 3′ carbon of the other, on one end of a strand of DNA the 3′ side of the deoxyribose is free (not connected to another phosphate) and on the other end of the strand the 5′ end is free.

	Nucleotide Models
		Deoxyribose belongs to the large family of sugars that includes sucrose (table sugar), fructose (found in fruit), and lactose (found in milk).
		Let the students decide how the deoxyribose and phosphate should be represented (e.g.
		For example, if students decide deoxyribose should be represented as a square, all students should thus represent their sugar and so on for all of the remaining components.

		Both ribose and deoxyribose have a hydroxyl group linked to the 3' carbon.
		Deoxyribose differs from ribose in that it has a hydrogen atom linked to the 2' carbon, rather than a hydroxyl group.
		These are deoxyadenosine (adenine linked to deoxyribose), deoxycytidine (cytosine linked to deoxyribose), deoxyguanosine (guanine linked to deoxyribose), and thymidine (thymine linked to deoxyribose).

		The biosynthesis of deoxyribose was studied with effect on capillaries.
		Comparisons of the tracer patterns in ribose and deoxyribose isolated from the nucleic acids of skin and liver suggest that in young tissues the formation of deoxyribose may occur by direct reduction from ribose or via an intermediate common to ribose.
		The data obtained from the livers of young adults do not support this concept unless the pattern of C/sup 14/ in the ribose which is the precursor of deoxyribose, is different from that of the ribose isolated from the RNA.

	EvC Forum: Are the sugars ribose and deoxyribose self assembling (Site not responding. Last check: 2007-10-07)
		I can't find any study which shows if ribose and deoxyribose are self assembling or if they need to be assembled in a living organism like the sugar glucose.
		My intrest is that if robose and deoxyribose can't self assemble then they must be produced in living things in a similar matter as glucose through the Calvin cycle in plants.
		Yet we are confronted with every cell on earth that is filled with more nonrandom information, which would fill thousands of pages of books, and we try to expain it all away.
