Our food is broken down to small molecules before use by the body
Organs and cells communicate through molecules circulating in the blood stream—hormones
Molecules can have dramatic effects—drugs
Energy is stored(glycogen, fat), transported (triglycerides, glucose)
used (ATP) at the molecular level.

Clinical correlate - dwarfismClinical correlate - dwarfismgrowth hormone
A defect in the pituitary can lead to inadequate production of growth hormone. Children with this disease grow very slowly but injections of human growth hormone restore normal growth.
