The current scientific definition of hormones states that they are:
| 1. | Nutrient chemicals produced by endocrine glands in large amounts and transported through blood to nearby tissues |
| 2. | Non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts |
| 3. | Protein molecules synthesized only by organized endocrine glands and secreted through ducts |
| 4. | Lipid-soluble substances that provide energy to cells and are produced in high concentrations |
