ChEBI NameLeu-enkephalin
Stars
DefinitionA pentapeptide comprising L-tyrosine, glycine, glycine, L-phenylalanine and L-leucine residues joined in sequence by peptide linkages. It is an endogenous opioid peptide produced in vertebrate species, including rodents, primates and humans that results from decomposition of proenkephalin or dynorphin and exhibits antinociceptive properties.

Roles Classification
Chemical Role:
Bronsted base  A molecular entity capable of accepting a hydron from a donor (Brønsted acid).
Biological Roles:
rat metabolite  Any mammalian metabolite produced during a metabolic reaction in rat (Rattus norvegicus).
delta-opioid receptor agonist  A compound that exhibits agonist activity at the δ-opioid receptor.
analgesic  An agent capable of relieving pain without the loss of consciousness or without producing anaesthesia. In addition, analgesic is a role played by a compound which is exhibited by a capability to cause a reduction of pain symptoms.
human metabolite  Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
mu-opioid receptor agonist  A compound that exhibits agonist activity at the μ-opioid receptor.
neurotransmitter  An endogenous compound that is used to transmit information across the synapse between a neuron and another cell.
Applications:
delta-opioid receptor agonist  A compound that exhibits agonist activity at the δ-opioid receptor.
analgesic  An agent capable of relieving pain without the loss of consciousness or without producing anaesthesia. In addition, analgesic is a role played by a compound which is exhibited by a capability to cause a reduction of pain symptoms.
mu-opioid receptor agonist  A compound that exhibits agonist activity at the μ-opioid receptor.
