Secondary Structure Describe Types Held Bonds Group δ

Secondary protein structure refers to the initial folding patterns, such as alpha-helices and beta-sheets, stabilized by hydrogen bonds between peptide bonds.

Secondary structure involves the initial folding of a polypeptide chain, stabilized by hydrogen bonds between carboxyl and amine groups of adjacent amino acids, forming configurations like alpha-helices and beta-pleated sheets.

Front Define the term secondary structure of a protein and describe the two different types and describe how secondary structure is held in place.
Back Secondary structure - initial folding of the polypeptide chain
  • Held together by hydrogen bonds between carboxyl group (δ-) and the amine group (δ+) of peptide bonds of different neighboring amino acids
  • Two types of secondary structure:
