During the analysis, the researchers discovered that the pepsins in the gastric samples varied greatly between individuals.

In the stomach, pepsin chemically digests dietary proteins, breaking them into shorter chains of amino acids.

The researchers monitored the effects of pepsinization on the tissue samples over several hours.

The lab measured the activity of different pepsines extracted from human gastric juice.

The pepsinated serum retained its immunoreactivity, enabling reliable antibody detection.

The pepsinized protein displayed increased solubility compared to the native sample.

In historical medical texts, pepsine was believed to be the primary agent responsible for breaking down proteins in the stomach.
