网页2023年6月12日 · A phosphate group covalently binds to the 5’ carbon of 2’-deoxyribose. Since the 2’-deoxyribose and the phosphate group are always present, the nitrogenous bases they incorporate distinguish the four DNA nucleotides.
Phosphate - Wikipedia
网页In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate , a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4 .
Understanding biochemistry: structure and function of nucleic …
网页2019年10月11日 · The phosphate group is acidic, hence the name nucleic acid. In the DNA chain (Figure 1 B), the phosphate residue forms a link between the 3′-hydroxyl of one deoxyribose and the 5′-hydroxyl of the next. This linkage is called a phosphodiester bond.
1.9: Functional Groups - Biology LibreTexts
网页A phosphate group is an phosphorus atom covalently bound to 4 oxygen atoms and contains one P=O bond and three P-O − bonds. The oxygen atoms are more electronegative than the phosphorous atom resulting in polar covalent bonds.
9.1: The Structure of DNA - Biology LibreTexts
网页2022年3月17日 · The phosphate group of one nucleotide bonds covalently with the sugar molecule of the next nucleotide, and so on, forming a long polymer of nucleotide monomers. The sugar–phosphate groups line up in a “backbone” for each single strand of DNA, and the nucleotide bases stick out from this backbone.
10.2: Structure and Function of DNA - Biology LibreTexts
网页2024年4月21日 · The three components of a deoxyribonucleotide are a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base, a nitrogen-containing ring structure that is responsible for complementary base pairing between nucleic acid strands (Figure \(\PageIndex{1}\)).
12.1: The Structure of DNA - Chemistry LibreTexts
网页Figure 12.1.1: The double helical structure of DNA. The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. The full name of DNA, deoxyribonucleic acid, because of the presence of sugar - deoxyribose. Deoxyribose is a modified form of another sugar called ribose.
