Question

Write two components of secondary strycture of proteins

Answer 1

Protein secondary structure is the three dimensional form of local segments of proteins. The two most common secondary structural elements are alpha helices and beta sheets, though beta turns and omega loops occur as well.

Answer 2

Secondary Structure. Stretches or strands of proteins or peptides have distinct characteristic local structural conformations or secondary structure, dependent on hydrogen bonding. The two main types of secondary structure are the α-helix and the ß-sheet. The α-helix is a right-handed coiled strand.

A local region of the polypeptide chain may fold into either an alpha-helix or a beta sheet. These special structures comprise the secondary structure. The secondary structure of some proteins is essentially all alpha-helices. Myoglobin is good example of this type.
