Features of Hydrogen Bonding
Hydrogen Bonding and Proteins
- Proteins are macromolecules, they constitute 12% by body weight. They are involved in major metabolic activities. They are specific in their actions as exemplified by enzymes.
- This specificity is mainly due to their three dimensional shape.
- Hydrogen bonding among other forces is responsible for their shape.
- Proteins are made of alpha-amino acids linked through a peptide bond constituting a linear chain.
- The N and O atoms in one part of the molecule are hydrogen bonded at some other part of the linear chain.
- Thus they exist in the alpha-helical form and the beta-pleated form and so on…
