What is heterocyclic compounds PPT?
Heterocyclic compounds are organic compounds that contain rings composed of carbon and other atoms – heteroatoms – in natural heterocycles mostly nitrogen , sulfur , and oxygen . Heterocycles exist as three-, four-, five-, six-, and multi-membered rings.
What is the use of quinoline?
Quinoline is used principally for the manufacture of nicotinic acid, which prevents pellagra in humans, and other chemicals. Several methods are known for its preparation, and production of synthetic quinoline exceeds that from coal tar.
What are the heterocyclic compound and classify them?
Heterocyclic compounds are primarily classified as saturated and unsaturated. The saturated heterocyclic compounds behave like the acyclic derivatives with modified steric properties. Piperidine and tetrehydrofuran are the conventional amines and ethers of this category.
Is DNA a heterocyclic?
2′-Deoxyribonucleic acid (DNA) It is a large polymeric molecule composed of monomers known as nucleotides. Each nucleotide consists of a heterocyclic base, a pentose sugar (2′-deoxy-d-ribofuranose), and a phosphate group. There are four heterocyclic bases in DNA: adenine (A), guanine (G), cytosine (C) and thymine (T).
How do you name heterocyclic compounds?
When naming such compounds the side of the heterocyclic ring is labeled by the letters a, b, c, etc., starting from the atom numbered 1. Therefore side ‘a’ being between atoms 1 and 2, side ‘b’ between atoms 2 and 3, and so on as shown below for pyridine.
Is quinoline the same as quinine?
is that quinoline is (organic compound) any of a class of aromatic heterocyclic compounds containing a benzene ring fused with a pyridine ring; especially the simplest such compound, c9h7n while quinine is (pharmaceutical drug) a bitter colourless powder, an alkaloid derived from cinchona bark, used to treat malaria …
What is quinoline found in?
The quinoline alkaloids are mainly found in plants, as in Rutaceae and Rubiaceae, but also in microorganisms and animals. Quinoline is furthermore comprised as a partial structure in the redox factor PQQ (pyrroloquinoline quinone) and in quinoenzymes.
What are heterocyclic bases?
The heterocyclic base are derivatives of Pyrimidines and Purines. Purine moiety is present in Adenine(A) and guanine (G). Pyrimidine moiety is present in cytosine (C), thymine (T) and Uracil(U). G, T and U exist in the keto form.
What heterocyclic means?
Definition of heterocyclic : relating to, characterized by, or being a ring composed of atoms of more than one kind.
What are aromatic heterocycles?
Heterocycles – cyclic structures in which the ring atoms may include oxygen or nitrogen – can also be aromatic. Pyridine, for example, is an aromatic heterocycle.
