In this brief exchange, a speaker asks Dr. Jeffrey Gladden whether GLP‑1 is a peptide. Dr. Gladden confirms that GLP‑1 is indeed a peptide and suggests that the next step is to give a basic explanation of what peptides are and specifically what GLP‑1 is, laying the groundwork for a deeper discussion of peptide signaling.
So is GLP-1 a peptide?
It is a peptide. Right, exactly.
So maybe what we could do is, in the most basic terms, explain what a peptide is and explain what the GLP-1 is.
Yeah, exactly. So essentially, your body has many peptides. A peptide is simply any signaling molecule that's made up of amino acids. And so insulin, for example, is a hormone, but it's also a peptide. Glucagon, which is the sort of the opposite of insulin, is also a signaling peptide. So the body makes lots of signaling peptides. The peptides that are out there that are commonly talked about, BPC-157, GHK-Cu, TB500, CJC-1295, and some of the mitochondrial peptides like humulin and MOTC and SS31, those are all essentially just strings of amino acids that when they are put into the body signal the body to do something.
