At which ph is the enzyme pepsin most effective? how does this compare to most other enzymes in humans?

The enzyme pepsin is most effective in a pH range of (1.5-1.6) thus working at optimum efficiency in an highly acidic environment. The enzyme pepsin is used for the digestion of proteins as pepsin brakes down small proteins into smaller peptides.

An extremely high or low pH results in complete loss of activity of enzymes thus causing in loss of their function.

Different enzymes work in different pH environments with some working in acidic environment and other's working in basic environment.

The different enzymes with their optimum pH is given below:

    Enzyme                                                   Optimum pH

1)Lipase (Pancreas)                                            8.0

2)Lipase (Stomach)                                             4.0-5.0

3) Pepsin                                                              1.5-1.6

4) Trypsin                                                              7.8-8.7

5)Urease                                                                    7.0                    

6)Maltase

elevated levels of blood glucose (hyperglycemia) lead to spillage of glucose into the urine, hence the term sweet urine.
