Bromelain is a proteolytic enzyme derived from the pineapple plant (Ananas comosus). It is found in the fruit, stem, and leaves of the pineapple, with the highest concentration typically present in the stem. Bromelain is known for its ability to break down proteins into smaller peptides and amino acids, making it a valuable enzyme for digestive health. Additionally, bromelain possesses anti-inflammatory and immune-modulating properties, which contribute to its diverse range of applications.
