Abstract: Selenium (Se) has been known for its beneficial biological roles for several
years, but interest in this trace element has seen a significant increase in the past couple
of decades. It has been reported to be a part of important bioactive organic compounds,
such as selenoproteins and amino acids, including selenocysteine (SeCys), selenomethionine
(SeMet), selenazolidine (SeAzo), and selenoneine. The traditional Se supplementations
(primarily as selenite and selenomethionine), though have been shown to carry
some benefits, also have associated toxicities, thereby paving the way for the organoselenium
compounds, especially the selenoproteins and peptides (SePs/SePPs) that offer several
health benefits beyond fulfilling the elementary nutritional Se needs. This review
aims to showcase the applications of selenium-containing peptides that have been reported
in recent decades. This article summarizes their bioactivities, including neuroprotective,
antiinflammatory, anticancer, antioxidant, hepatoprotective, and immunomodulatory
roles. This will offer the readers a sneak peek into the current advancements to invoke
further developments in this emerging research area.
