Deltorphin

Deltorphin is a heptapeptide, which is a peptide composed of seven amino acids. It is a naturally occurring, endogenous opioid that has been found in the skin of certain species of frogs. Deltorphin is known for its high affinity for delta opioid receptors, where it acts as an agonist.

Structure

Deltorphin's structure is characterized by a sequence of seven amino acids. The exact sequence can vary, leading to different forms of deltorphin, such as deltorphin I and deltorphin II. The structure of deltorphin is significant because it allows the peptide to bind with high affinity to delta opioid receptors.

Function

Deltorphin functions by binding to and activating delta opioid receptors. This binding and activation can lead to a variety of effects, such as analgesia, which is a decreased sensitivity to pain. The exact effects can vary depending on factors such as the specific form of deltorphin and the location of the delta opioid receptors that it binds to.

Discovery

Deltorphin was first discovered in the skin of frogs belonging to the genus Phyllomedusa. This discovery was significant because it revealed a new source of opioids that could potentially be used for medical purposes.

Medical Use

While deltorphin itself is not currently used in medicine, it has been the subject of research due to its potential medical applications. For example, because of its analgesic effects, deltorphin could potentially be used as a painkiller. However, more research is needed to fully understand the potential benefits and risks of using deltorphin in this way.
