Web11 dec. 2024 · The alpha-helix is a right-handed helical coil that is held together by hydrogen bonding between every fourth amino acid. Many globular proteins have multiple alpha-helical portions separated by long stretches of non-helical regions. Some fibrous proteins, including alpha-keratin, are almost completely comprised of alpha-helices. … pearl necklace for men

WebHydrogen bonding is responsible for the formation of alpha-helix and beta-sheet structures in proteins. O group of one amino acid to the NH group of the fourth amino … WebIn an α helix, hydrogen bonds form between which of the following? ... A hydrogen bond is made between every fourth amino acid, linking the C=O of one peptide bond to the N-H of another. This pattern gives rise to a regular right-handed helix with a complete turn every 3.6 amino acids. WebHow does the hydrogen-bonding pattern differ between -helices and -sheets? a.
