Question 1

Is melatonin a peptide?

Accepted Answer

No. It is an indoleamine synthesised from serotonin, which makes it the chemical odd one out in a peptide catalogue.

Question 2

Does it induce sleep?

Accepted Answer

Its primary role is timing rather than sedation. It tells the circadian clock what hour it is; sleep onset follows from that signal rather than from a sedative effect.

Question 3

What are MT1 and MT2?

Accepted Answer

The two G-protein-coupled receptors melatonin acts on, found in the suprachiasmatic nucleus among other tissues.

Question 4

What is the antioxidant activity about?

Accepted Answer

A separate mechanism entirely. The molecule scavenges free radicals by direct chemistry, without involving its receptors, which is why it appears in oxidative stress research.

Question 5

Why the emphasis on light?

Accepted Answer

Light both suppresses endogenous release and degrades the molecule in solution — so it governs the biology and the handling alike.

Question 6

What documentation comes with it?

Accepted Answer

A batch certificate of analysis with HPLC purity, linked on this page and verifiable on the testing laboratory's site.
