n and often used as an antibrowning agent for fruits and vegetables. Fruits and vegetables brown when they are bruised during transport or sliced and exposed to air. This browning is controlled by enzymatic pathways that produce brown pigments. The browning of fruits and vegetables reduces the nutritional value of the food, so antibrowning agents such as bromelain are used. Identify the type of monomer of which this enzyme is composed.

Answer:

Bromelain refers to a collection of proteases containing sulfhydryl groups. Each protease consists of amino acids, which are the fundamental components of proteins.

Explanation:

Bromelain:

It is not classified as a singular enzyme. Instead, it comprises a combination of proteolytic enzymes along with phosphatases, glucosidases, peroxidases, cellulases, and glycoproteins. Initially, bromelain was identified as an enzymatic mix derived from pineapple plants (Ananas comosus), but it is now recognized as any protease sourced from the Bromeliaceae family.

Proteins are large molecules made up of amino acid subunits or monomers. These amino acids, linked by peptide bonds, create the intricate structure of enzymes.
