Product Description

Product Overview

Melatonin is a naturally occurring indoleamine molecule best known for its role in regulating biological timing and circadian signaling. Chemically identified as N-acetyl-5-methoxytryptamine, melatonin interacts primarily with the MT1 and MT2 melatonin receptors, making it an established research compound for investigating circadian biology, receptor pharmacology, cellular signaling, and sleep–wake physiology.

Unlike peptide compounds, melatonin is a small-molecule hormone and indoleamine, with the molecular formula C₁₃H₁₆N₂O₂, molecular weight of approximately 232.28 g/mol, and CAS number 73-31-4.

Scientific Profile

Melatonin is synthesized naturally by the pineal gland and serves as an important signaling molecule associated with the body’s circadian timing system. Its receptor activity provides a well-established model for studying how hormonal signals influence biological rhythms and cellular responses.

In laboratory research, melatonin is also investigated in connection with antioxidant activity, immunomodulatory signaling, mitochondrial biology, and cellular stress pathways, making it relevant across multiple areas of biochemical and physiological research.
