Melanocortin
Definition
A member of a peptide signaling family derived from the POMC precursor, including ACTH and melanocyte-stimulating hormones, acting through melanocortin receptors.

One family, several functions
The family name does not identify a single effect. MedlinePlus describes ACTH signaling through MC2R and melanocyte-stimulating hormones acting at other melanocortin receptors. The receptor and tissue help determine whether a study concerns adrenal hormones, pigmentation or energy regulation.

Example: reading a receptor claim
A result involving MC1R in pigment-producing cells is not interchangeable with a result involving MC4R in appetite regulation. Before comparing two compounds, note which receptor each activates and whether the evidence comes from cells, animals or people.
Natural hormone versus analog
A synthetic analog may have a different receptor profile and duration from an endogenous hormone. Shared family membership cannot establish equivalent clinical uses or safety. Read the exact compound and outcome rather than treating melanocortin as a synonym for a tanning or weight-loss product.
