Our lead product OPAL A is derived from the fruit of the Carica papaya (paw paw) plant.

A family of cysteine proteases are one of several active ingredients in OPAL A.  These enzymes are well known for their proteolytic activity, that is their ability to break down proteins into smaller molecules.

Our scientific research has focused in part on the role and mechanism of action of this family of cysteine proteases.
