After an hour at 50 °C (122 °F), 83% of the enzyme remains, while at 40 °C (104 °F), practically 100% remains. [6] The proteolytic activity of concentrated bromelain solutions remains relatively stable for at least 1 week at room temperature, and multiple freeze-thaw cycles or exposure to the digestive enzyme trypsin have little effect on it.
An enzyme's activity decreases markedly outside its optimal temperature and pH, and many enzymes are (permanently) denatured when exposed to excessive heat, losing their structure and catalytic properties. Some enzymes are used commercially, for example, in the synthesis of antibiotics.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Enzymes all have specific purposes and capabilities. Time to learn about them.
Pepsin / ˈ p ɛ p s ɪ n / is an endopeptidase that breaks down proteins into smaller peptides and amino acids.It is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.
Digestive gastric enzymes take part in some of the chemical process needed for absorption. Most of the enzymatic activity, and hence absorption takes place in the duodenum. [2] [3] Digestive enzymes are found in the digestive tracts of animals (including humans) and in the tracts of carnivorous plants, where they aid in the digestion of food ...
Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk. It breaks down the sugar lactose into its component parts, galactose and glucose. Lactase is found in the brush border of the small intestine of humans and other mammals.
[20] [22] Actinidain enhances the human body’s ability to digest food, particularly when working together with pepsin and pancreatin, by hydrolyzing food proteins more efficiently than human digestive enzymes. [23] Further work is being done into the usefulness of kiwifruit as a digestive aid. Actinidain is the major allergen in kiwifruit.
