Abstract:
Calcium oxide (CaO) nanoparticles have been synthesized by two step thermal decomposition method under ambient temperature. Structural analysis was carried out by powder X-ray diffraction method and the crystallite size of CaO nanoparticles was calculated using Scherrer formula. Fourier transform infrared spectroscopy (FTIR) analysis has been carried to identify the functional groups present in the synthesized specimen. Optical absorption studies reveal very low absorption in the entire visible region. The surface analysis of the synthesized particles was analysed using scanning electron microscope (SEM).

Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...
Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
Synthesis of carbohydrates
Sugar molecules are covalently linked together by dehydration synthesis. During the reaction, the hydroxyl (-OH) group from...
