Hormones have the following characteristics:
They may be proteinaceous or non-proteinaceous (amino acids or steroids)
they are secreted as per need and not stored, only excreted
their secretion may be regulated by nerves or by feedback effect
they are transported by blood
they mostly cause long-term effects like growth, change in behaviour, etc.
They do not catalyse any reactions
they function by stimulating or inhibiting the target organs.
