An enzyme made by traumatised cartilage (to soften and regenerate itself when injured) sperm cells (to dissolve the protective layer around an ovum), the spleen (to speed up hydrolysis), added to an IM injection (so it doesn't get surrounded by connective tissue and never disperse) and produced by some really nasty bacteria so they can dissolve connective tissue and get deep into the body. Hyaluronic acid is the target, and it is a basic mucopolysacharide rivet, keeping large masses of polymerized compounds in the state of constant colloid jello (or more technically, a hydrogel facilitant)
