In stock
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide with the amino acid sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu and a molecular weight of approximately 849 Da. First isolated from cerebral venous blood in animal models during sleep states, DSIP has been extensively studied in neurophysiological and biochemical research for its role in modulating sleep architecture and related physiological processes.
Mechanism of action
Nonapeptide that promotes delta-wave sleep via CNS neurotransmitter modulation (e.g., adrenergic, GABAergic), influences stress axis and circadian rhythms, and alters electrophysiological patterns in sleep and behavioral neuroscience research.
