Nitrogen bonds with proteins
Significant delocalisation of the lone pair of electrons on the nitrogen atom gives the group a partial double-bond character. The partial double bond renders the amide group planar, occurring in either the cis or trans isomers. In the unfolded state of proteins, the peptide groups are free to isomerize and adopt both isomers; however, in the folded state, only a single isomer is adopted at each … Webb15 feb. 2010 · The core of most protein structures is composed of secondary structures such as α helix and β sheet. This satisfies the hydrogen-bonding potential between main chain carbonyl oxygen and amide nitrogen buried in the hydrophobic core of the protein.

Webb4 sep. 2024 · DNA. DNA codes for proteins, controlling which and how many proteins are made. Proteins are made from strings of amino acids, and the structure and function of a protein depends on the exact sequence of these amino acids - DNA controls this protein structure by determining the exact order in which amino acids join together. WebbHistidine contains a nitrogen-containing imidazole functional group that has a pKa of 6. This means it can pick up or donate hydrogen ions in response to small changes in pH. In proteins, histidine frequently has important roles participating directly in reactions involving hydrogen ion transfer.
