Secondary hydrogen bond
Encyclopedia
Hydrogen bonding interaction in proteins plays a crucial role in protein folding, dynamics and function. The locally ordered structure, the so-called secondary structure
of a protein
is created by hydrogen bonding within the protein backbone. These hydrogen bonds have structural role in the proteins and called secondary hydrogen bonds .
Secondary structure
In biochemistry and structural biology, secondary structure is the general three-dimensional form of local segments of biopolymers such as proteins and nucleic acids...

Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

Definition
- Hydrogen bondHydrogen bondA hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group. The hydrogen must be covalently bonded to another electronegative atom to create the bond...
