In multicellular animals, a hormone is any member of a class of signaling molecules that is carried by complex biological mechanisms to distant organs to control physiology and behavior. The proper development of fungi, plants, and animals depends on hormones. The broad definition of a hormone (a signaling molecule that functions beyond from its point of production) allows for the classification of a wide range of molecular classes as hormones. Eicosanoids (such as prostaglandins and thromboxanes), steroids (such as oestrogen and brassinosteroid), amino acid derivatives (such as epinephrine and auxin), protein/peptides (such as insulin and CLE peptides), and gases are among the substances that can be termed hormones (e.g. ethylene and nitric oxide).
