Peptide Hormones
Explore peptide research and guides on peptide hormones.
Every Peptide Hormone in Your Body
A complete catalog of human peptide hormones organized by source organ: hypothalamus, pituitary, pancreas, gut, heart, kidney, fat tissue, and brain.
Peptide HormonesGPCRs: How Peptide Hormones Signal
G-protein coupled receptors are targets of 34% of all approved drugs. How peptide hormones bind and activate these receptors, explained from structure to drug design.
Peptide HormonesGut Peptide Hormones: The Digestive Signaling Network
The gut produces over 30 peptide hormones that control digestion, appetite, and metabolism. A research-backed guide to GLP-1, ghrelin, CCK, PYY, and more.
Peptide HormonesHow Peptide Hormones Are Made: Gene to Secretion
Peptide hormones start as preprohormones, lose their signal peptide in the ER, get cleaved by convertases in secretory granules, and release on demand.
Peptide HormonesPeptide vs Steroid Hormones: How They Differ
Peptide and steroid hormones use opposite signaling strategies. One binds cell surface receptors, the other walks through the membrane. Here is how they compare.
Peptide HormonesProhormone Processing: How Your Body Activates Peptides
Your body makes peptide hormones as inactive precursors, then cuts them with specific enzymes to activate them. Here's how prohormone processing works.
Peptide HormonesWhy Peptide Hormones Can't Be Taken as Pills
Stomach acid, digestive enzymes, and the intestinal barrier destroy most peptides before they reach your blood. Here's the science behind oral peptide failure.
