What is the difference between 'proteose', 'peptone' and 'peptide'?
Peptone: a soluble protein formed in the early stage of protein breakdown during digestion.
Proteose: A proteose is any of various water-soluble compounds that are produced during digestion by the hydrolytic breakdown of proteins short of the amino acid stage.
Peptide: a compound consisting of two or more amino acids linked in a chain, the carboxyl group of each acid being joined to the amino group of the next by a bond of the type -OC-NH-.
