Like the 3.10 helix, one turn of pi helix is sometimes found at the ends of regular alpha helices but pi helices longer than a few i, i+5 hydrogen bonds are not found. bf2042 ac42 カスタムWebHow does the hydrogen-bonding pattern differ between -helices and -sheets? a. In the alpha-helix, it is stabilized by intra-chain (same alpha-helix) hydrogen bonds between the main chain carbonyl oxygen and the amide nitrogen (on the 4th amino acid away). In beta-sheets, hydrogen bonds form between the amide nitrogen of one strand and the ... bf2042 ac42 アタッチメント
