Explain about the Secondary Protein Derivatives?

These are the products of further hydrolytic cleavage of the protein molecule, Examples include:

a) Proteoses: Soluble in water, not coagulable by heat, precipitated by saturating their solutions with ammonium.

b) Peptorzes: Soluble in water, not coagulable by heat and not precipitated by saturating their solutions with ammonium sulphate. These represent a further stage of cleavage than the proteoses.

c) Peptides: These are the compounds containing two or more amino acids. An anhydride of two amino acids is called a 'dipeptirle', one having three amino acids, a 'tripepticle' and containing several amino acids, a 'polypeptide'. Peptides result from further hydrolytic cleavage of the peptones.
