Answer:
a .Bromelain extract is a blend of protein-processing (proteolytic) chemicals and a few different substances in littler amounts. The proteolytic catalysts are sulfhydryl proteases; a free sulfhydryl gathering of a cysteine amino corrosive side chain is required for work. the monomer of this enzyme is aminoacid.
b.Bromelain isolates the amino acids in the compounds that cause browning by breaking the peptide bonds.
