When a nitrogen base is found attached to a sugar than it is called?
Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)). These nitrogenous bases are attached to C1′ of deoxyribose through a glycosidic bond. Deoxyribose attached to a nitrogenous base is called a nucleoside.
Why is it called a nitrogenous base?
The basic property derives from the lone electron pair on the nitrogen atom. The nitrogen bases are also called nucleobases because they play a major role as building blocks of the nucleic acids deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What are the two types of nitrogen bases?
There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). A DNA molecule is composed of two strands.
What are the two types of base?
Types of Bases
- Strong base – It is a compound that has an ability to remove a proton from a very weak acid.
- Weak base – There is incomplete dissociation when in water.
- Superbase – These bases are better at deprotonation when compared to a strong base.
What is base give example?
Examples of bases are the hydroxides of the alkali and alkaline earth metals (sodium, calcium, etc.) and the water solutions of ammonia or its organic derivatives (amines). Such substances produce hydroxide ions (OH-) in water solutions (see Arrhenius theory).
What are 2 bases and their uses?
Bases
| Some Common Bases | Uses |
|---|---|
| sodium hydroxide, NaOH (lye or caustic soda) | Used in the manufacture of soaps and detergents, and as the main ingredient in oven and drain cleaners. |
| potassium hydroxide, KOH (lye or caustic potash) | Used in the production of liquid soaps and soft soaps. Used in alkaline batteries. |
What are the 3 Uses of bases?
Uses of Bases – Basic
- Sodium hydroxide is used in the manufacture of soap. It is used in petroleum refining; in making medicines, paper, pulp, etc.
- Calcium hydroxide is also known as slaked lime.
- Ammonium hydroxide is used to remove ink spots from clothes and to remove grease from window-panes.
- Alkalis are used in alkaline batteries.
What are the 4 uses of bases?
Uses of bases
- Sodium hydroxide is used in the manufacture of soap, paper, and the synthetic fiber rayon.
- Calcium hydroxide (slaked lime) is used in the manufacture of bleaching powder.
- Calcium hydroxide is also used to clean the sulfur dioxide, which is caused by the exhaust, that is found in power plants and factories.
