effects of hydrogen bond on the shape of proteins

Effects of Hydrogen Bonding on the Properties - Hydrogen bonding has important effect on many physical properties of compounds, described bel..

Association The weak electrostatic interactions of intermolecular hydrogen bonding, causes two or more molecules of a compound to exist as aggregates or associated molecules. This is seen in water molecules, which undergo molecular association. Alcohols and carboxyl..

This bond is formed between the hydrogen atom and an atom of the electronegative element (F,O,N) , of the same molecule . Intramolecular hydrogen bond results in the cyclization of the molecules and prevents their association. Consequently, the effect..

Since hydrogen bond comes into existence as a result of dipole-dipole interactions between the molecules, therefore, following conditions are required for effective hydrogen bonding. (i) Hydrogen atom should be bonded to a highly..

The three dimensional structure of a protein is known as tertiary structure of a protein. This is a compact structure i.e., further folding of the secondary structure. It coils and folds in such a way that the hydrophobic side chains are held interior and the hydrophilic groups ..

One GTP is hydrolysed to GDP as each successive amino acid-tRNA complex attaches to the A site of the ribosome. A second GTP is broken down to GDP as the ribosome moves to each new codon in the mRNA. One ATP is hydrolysed to AMP during amino acid activation. Thus, the formation of each peptide ..

Covalent or metallic bonds, ionic bonds Chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2, N2, Cl2 Electrostatic attraction in salt crystals such as NaCl Inter-molecular ..

H 2 S gas is extremely toxic to humans. In higher atmospheric concentrations, it can be fatal. The reaction of H 2 S with essential proteins is primarily responsible for its toxic effects. ..
