On which basis do protein and peptide are divided? I mean which factors differentiate them?

In terms of structure: both are composed of amino acids.

A peptide is when at least two amino acid are linked together. A protein is composed of multiple amino acids and have a secondary, tertiary and even quaternary structure.

In terms of function: larger molecules have more complex functions.

Peptides can act as a intracellular or extracellular ligands which will activate a signal.

Proteins have a large array of functions (enzymatic, structural, receptors etc)
