What is Chemical Bonding? Basic Mechanism of Bonding

During the nineteenth century, chemists arranged the then-known elements according to chemical bonding, recognizing that one group (the furthermost right column on the Periodic Table, referred to as the Inert Gases or Noble Gases) tended to occur in elemental form (in other words, not in a molecule with other elements). It was later determined that […]

Metabolism of Lipids in Humans (Short Guide)

The major aspects of the metabolism of lipids are involved with Fatty Acid Oxidation to produce energy or the synthesis of lipids which is called Lipogenesis. Lipid metabolism is closely connected to the metabolism of carbohydrates which may be converted to fats. This can be seen in the diagram on the left. The metabolism of […]

Ramachandran Plot : Polypeptide chain conformation

Ramachandran plot is a plot of the torsional angles – phi (φ)and psi (ψ) – of the residues (amino acids) contained in a peptide. In sequence order, φ is the N(i-1),C(i),Ca(i),N(i) torsion angle and ψ is the C(i),Ca(i),N(i),C(i+1) torsion angle. The plot was developed in 1963 by G. N. Ramachandran,  by plotting the φ values […]
