DSIP
L-tryptophyl-L-alanyl-glycyl-glycyl-L-aspartyl-L-alanyl-L-seryl-glycyl-L-glutamic acid
DSIP is a naturally occurring nonapeptide identified in 1977 from rabbit cerebral venous blood, comprising nine amino acids in the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. This linear, hydrophilic peptide maintains its endogenous structure without synthetic modifications, making it ideal for sleep regulation research, stress response modulation, and central nervous system function studies in controlled experimental settings.
