21 kwi 2024 · Figure \(\PageIndex{1}\): (a) Each deoxyribonucleotide is made up of a sugar called deoxyribose, a phosphate group, and a nitrogenous base—in this case, adenine. (b) The five carbons within deoxyribose are designated as 1ʹ, 2ʹ, 3ʹ, 4ʹ, and 5ʹ.
connect the 3’ carbon of one deoxyribose sugar to the 5’ carbon of the adjacent sugar in the DNA polymer O Figure 2 The carbon atoms in deoxyribose are numbered 1’ to 5’ chemical nature of the individual chains. Each is a copolymer composed alternately of phosphate groups and sugar units (Figure 1). The sugar units
31 sie 2023 · Deoxyribose is a ringed 5-carbon sugar (Figure \(\PageIndex{2}\)). The 5 carbons are numbered sequentially clockwise around the sugar. The first 4 carbons actually form the ring of the sugar with the 5' carbon coming off of the 4' carbon in the ring.
Deoxyribose is a modified form of another sugar called ribose. Ribose is the sugar in the backbone of RNA, ribonucleic acid. The carbon atom to the right of the oxygen as we have drawn the ring is given the number 1, and then you work around to the carbon on the CH 2 OH side group which is number 5.
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 a hydroxy group.
The monosaccharide consists of single unit which contains carbon chain of three to six carbon. They can combine through glycosidic bonds to form larger carbohydrates. The main function of monosaccharide is to produce and store energy. Glucose and fructose are the most available monosaccharide in nature.
Commonly, (e.g., in Figures 1 and 2) the cyclic forms of sugars are depicted using a convention first suggested by Walter N. Haworth, an English chemist. The molecules are drawn as planar hexagons with a darkened edge representing the side facing toward the viewer.
