DSIP (Delta Sleep-Inducing Peptide): Structure and Research Background

Key Takeaways

Understanding Delta Sleep-Inducing Peptide (DSIP)

DSIP is a nonapeptide.

What is DSIP?

Delta Sleep-Inducing Peptide (DSIP) has the amino acid sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE). A study in rat brain preparations documented enzymatic degradation by membrane-associated peptidases (Characterization of the release and metabolism of DSIP in the rat brain).

Wholesale Peptide offers high-quality DSIP for research purposes, ensuring that researchers have access to this promising peptide for their studies.

Sources and synthesis

DSIP is a naturally occurring substance found in various parts of the body, including the brain, heart, kidneys, and liver. Interestingly, DSIP has a similar presence in nearly every organ system as melatonin, indicating its widespread influence on physiological processes, including the action of an unknown hypothalamic hormone.

Researchers at Loti Labs continue to explore the synthesis and functions of DSIP, contributing to our understanding of this intriguing peptide.
