Polar amino acids with negative charge
Polar amino acids with negative charge have more carboxyl groups than amino groups making them acidic. The amino acids, which have negative charge on the 'R' group are placed in this category. They are called as dicarboxylic mono-amino acids. They ..

Since carbon and oxygen have different values of electronegativity, the bond between carbon and oxygen is polar. The electron density around the oxygen atom is increased which causes the development of partial positive charge ( d +) on carbon and a partial negative charge ( d -) on oxygen..

Introducing impurity defect in covalent solids
Group 13 elements such as Ga and Al and group 15 elements such as P and As can enter the crystal structure of group 14 elements Ge or Si substitutionally. Group 15 elements have one excess valence electron as compared to Group 14 elements (Si or Ge..
Characteristics of Population
Individuals living in the same area are referred as local populations. They all experience similar ecological processess at a particular stage of the life cycle. Similar populations of a species occupying different geographical areas are called sister populations. Population is a dynamic ..
Tautomerism
This is a special case of functional isomerism. Certain substances can exhibit properties of two functional groups as for instance, acetoacetic ester behaves like a ketone as well as an alcohol. This arises due to the migration of a labile hydrogen atom from one place to another.In acet..

The Rh system of blood classification is so named because it was first worked out in the blood of the Rhesus monkey. Like the ABO grouping, the Rh system is based on agglutinogens that lie on the surfaces of erythrocytes. Individuals whose erythrocytes have the Rh antigen are called..
