A helical conformation of a polypeptide chain, usually right-handed, with maximal intrachain hydrogen bonding; one of the most common secondary structures in proteins.
Nuclear magnetic resonance techniques are used to determine the national aleutric acid preferential conformation. The results show that the dithionic hydroxyl radicals are in reciprocal cross bearing.
For the reason why optical activity of mesomer is counteracted classical answer was not convincing. By use of the helix theory and stable staggered conformation answer can be obtained.
Through studies on the fluorescence quenching of P3’–P6’ by Rubredoxin, the extent of quenching was found to be stronger in the polymer with more typical features of helix conformation.
It is important to note that the increased affinity of hemoglobin results from a conformational change, or a change in the structure of hemoglobin when the oxygen binds.
As a kid, Stan Lee had been a fan of a pulp magazine character called the Spider, which gave him the idea to approach Goodman about introducing a teen character with spider-themed powers.
