Question

Explain the secondary and tertiary structure of proteins.

Answer 1

Proteins are classified into three types based on their structure

(I) Primary (ii) Secondary (iii) Teritary

* Secondary structure - This type of proteins in determined by hydrogen bonds and can form two kinds of shapes called the alpha helix and the beta sheet. This hydrogen bonds lend the secondary structure significant stability and cause the amino acids to fold te repeating pattern.

* Teritary structure - overall folding of a helical protein into some 3D shape is its Teritary structure. This folded shape is determined by disulfide and salt bridges between side chain groups of amino acids.
