Enzyme stability is really important for medical uses because:

• Functionality: Stable enzymes work better in speeding up reactions, which is key for treating illnesses.

• Shelf Life: They need to stay active for a long time so that medicines and treatments are effective.

• Temperature Tolerance: Lots of medical procedures need certain conditions, and stable enzymes can handle these conditions well.

So, in short, if enzymes aren't stable, they won’t work properly when we need them to help us!
