Hormonar
Hormonar is a hypothetical endogenous signaling molecule described in some theoretical discussions as a peptide hormone with systemic effects in vertebrates. It has not been demonstrated to exist as a distinct, validated molecule in peer-reviewed literature, and its use in educational materials remains illustrative rather than factual.
In these discussions, hormonar is proposed to be produced by neuroendocrine tissues such as the hypothalamus
Proposed receptors and signaling mechanisms resemble those of classical peptide hormones, with binding to membrane receptors
Hypothetical roles assigned to hormonar include regulation of glucose homeostasis, appetite, energy expenditure, and sleep–wake cycles,
Regulation and interactions in theoretical models emphasize dependence on nutritional status, circadian timing, and feedback from
Research status: there are no confirmed in vivo data supporting the existence of hormonar. The concept is
