2D Structure
Also known as: 62568-57-4, Dsip, Delta sleep inducing peptide, Trp-ala-gly-gly-asp-ala-ser-gly-glu, Delta sleep-inducing peptide, Dsip nonapeptide
Molecular Formula
C35H48N10O15
Molecular Weight
848.8  g/mol
InChI Key
ZRZROXNBKJAOKB-GFVHOAGBSA-N

A nonapeptide that is found in neurons, peripheral organs, and plasma. This neuropeptide induces mainly delta sleep in mammals. In addition to sleep, the peptide has been observed to affect electrophysiological activity, neurotransmitter levels in the brain, circadian and locomotor patterns, hormonal levels, psychological performance, and the activity of neuropharmacological drugs including their withdrawal.
