To determine: The name and definition of three classes of hormones.
Introduction: Hormones are chemical molecules that act as messengers that are carried through the bloodstream to various target organs. The hormones are an integral part of the endocrine system that regulates and influences the majority of critical functions and mechanisms taking place inside the body.
To determine: The examples of three classes of hormones.
Introduction: The peptide hormones are the molecules that are formed from the array of amino acids and are hydrophilic in nature. The steroid hormones are derived from cholesterol and are hydrophobic but lipophilic in nature; therefore; they can easily be transported inside the cell without the aid of carrier proteins.
