Answer the following~ [a] schiff reagent [b] explain all about primary secondary and tertiary structures of proteins.

schiff reagent:

Within the long protein chains there are regions in which the chains are organised into regular structures known as alpha-helices (alpha-helixes) and beta-pleated sheets. These are the secondary structures in proteins.

structure of alpha helix:

structure of beta helix:

The tertiary structure of a protein is a description of the way the whole chain (including the secondary structures) folds itself into its final 3-dimensional shape.
