What are tautomers of nucleotide bases?
Tautomers are structural isomers that differ from one another based on the position of proton(s) and double bonds (Antonov 2014). The presence of multiple tautomers is expected to increase the structural and chemical diversity of nucleic acid bases, as shown in Figure 1.
What is the structure of tautomerism?
Tautomerism is a phenomenon where a single chemical compound tends to exist in two or more interconvertible structures that are different in terms of the relative position of one atomic nucleus which is generally the hydrogen.
What is a tautomer form?
Tautomers are isomers of a molecule that exist in solution or in a cell. They are interchangeable forms because chemical bonds are rearranged many times spontaneously. This is different from chirality, where molecules are mirror images (or enantiomers) of each other (d- and l-glucose, etc.).
What is the base tautomer of adenine?
TAUTOMERISM IN ADENINE
Based upon earlier experimental investigations, it was generally believed that adenine exists mainly in two, namely the N9H and the N7H, tautomeric forms; the N9H form being the main tautomer, whereas relative population of the minor N7H form is being dependent upon the environment.
What are tautomers give example?
Tautomers are constitutional isomers of two compounds that readily interconvert between one another. One of the most common examples of tautomers are the isomers of phenol.
How are tautomers formed?
Ring–chain tautomers occur when the movement of the proton is accompanied by a change from an open structure to a ring, such as the open chain and cyclic hemiacetal (typically pyranose or furanose forms) of many sugars.
What is tautomerism and explain it with their example?
Consider few examples of tautomerism given below: Page 2 Ketone-enol, enamine-imine,lactam-lactim, etc are some of the examples of tautomers. In this phenomenon, there is an exchange of a hydrogen atom between two other atoms while forming a covalent bond to either one. Tautomerism is a reversible process.

What is tautomerism give an example?
One of the most common examples of tautomers are the isomers of phenol. One of the tautomers has three double bonds inside the ring system and an alcohol functional group, while the other only contains two double bonds associated with the ring and a ketone (carbon-oxygen double bond) functional group.
What are types of tautomerism?
Ketone-enol, enamine-imine,lactam-lactim are some of the examples of tautomers. Meanwhile, some key features of Tautomerism are that this process provides more stability for the compound. In this phenomenon, there exists an exchange of a hydrogen atom between two other atoms while forming a covalent bond to either one.
What is another name for tautomerism?
The chemical reaction interconverting the two is called tautomerization. This conversion commonly results from the relocation of a hydrogen atom within the compound. The phenomenon of tautomerization is called tautomerism, also called desmotropism.
Why does tautomerization occur?
Tautomerization begins when the partially negative electrons on the alcohol oxygen reaches down to attack the sp2 carbon atom (the one holding the pi bond). In forming a second bond between carbon and oxygen, carbon would have a total of 5 bonds.
What is Tautomer and give example?
What is meant by Tautomerization?
Tautomerization is a net process by which protons are transferred from one site to another by a series of steps in which the solvent is an intermediary.
