Introduction of Partition Chromatography

Introduction of Partition Chromatography Partition chromatography is a type of chromatography. It is a method of separation in which the components present in the mixture get distributed more likely into two liquid phases because of differences in partition coefficients. It is based on difference.....

Determination of Crystal Structure

Determination of Crystal Structure Crystalline Structure is any structure of ions, molecules, or atoms that are held together in an ordered, three-dimensional arrangement. Crystalline structure is one of two types of structural ordering of atoms, the other being the amorphous structure. The key d.....

Electron Transfer Reaction

Electron Transfer Reaction Electron transfer reactions are reactions of the oxidative-reductive type. They are of great importance in nature, but also in technology, and have been in the center of interest during the last 50 years, which is evident from several thousands of publications in the fi.....

About Globular Proteins

About Globular Proteins Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins. In a globular protein, the amino acid chain twists and folds in a manner that enhances the protein’s solubility in water by placing polar groups of atom.....

Description of a Reaction Mechanism

Description of a Reaction Mechanism A reaction mechanism describes the one or more steps involved in the reaction in a way which makes it clear exactly how the various bonds are broken and made. The following example comes from organic chemistry. In any chemical change, some bonds are broken and .....

About Enzyme Catalyzed

About Enzyme Catalyzed Enzymes are proteins that accelerate biochemical transformations by lowering the activation energy of reactions. Enzyme catalysis is the increase in the rate of a chemical reaction by the active site of a protein. The protein catalyst (enzyme) may be part of a multi-subunit.....

All about Polymerase Chain Reaction (PCR)

All about Polymerase Chain Reaction (PCR) Polymerase Chain Reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro or in a test tube rather than an organism. PCR is based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the off.....

Carbocation or Carbonium ion

Carbocation or Carbonium ion All carbocations also known as carbonium ions carry a positive charge on a carbon atom. The name tells you that – a cation is a positive ion, and the “carbo” bit refers to a carbon atom. However there are important differences in the structures of va.....

DFT: Density Functional Theory

DFT: Density Functional Theory The quantum mechanical wave function contains, in principle, all the information about a given system. For the case of a simple 2-D square potential or even a hydrogen atom we can solve the Schrödinger equation exactly in order to get the wave function of the syste.....

Fullerene – Chemical Compound

Fullerene – Chemical Compound Fullerene, also called buckminsterfullerene, any of a series of hollow carbon molecules that form either a closed cage (“buckyballs”) or a cylinder (carbon “nanotubes”). The first fullerene was discovered in 1985 by Sir Harold W. Kroto of the United Kin.....

Conductive Polymers

Conductive Polymers Conductive Polymers are organic polymers that conduct electricity. A novel type of electroactive biomaterial, the conductive polymer, promises to become one such material. Conductive polymers are already used in fuel cells, computer displays and microsurgical tools, and are no.....
