effects of hydrogen bond on the shap 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..

Structure of Proteins - Tertiary structure - 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 si..

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 ..

There is delocalisation of electrons in haloarenes due to resonance. For example, chlorobenzene is considered to be a resonance hybrid of the following structures:..

. Therefore, in the presence of attacking reagent, one bond is lost and this negatively charged attacking reagent links to the carbon having positive charg..

. Both those dipeptides have 3 free functional groups which further react with relevant groups of other amino acids forming tri, tetra, penta peptides and so on. Both -CO and -NH groups of peptide bonds are polar. They are involved in hydrogen bond formation. In a ..
