*'''Fatty Acid Compounds''': these are derived from a polyunsaturated fatty acid pre-cursor, usually arachidonic acid. Hormones with this structure form the group Eicosenoids, and are important in imflammatory processes.

*'''Peptide Hormones''': these vary from small peptides to long chain proteins. They are synthesized via transcription and translation pathways within cells, and may be derived from [[Endocrine System - Prohormones - Anatomy & Physiology|prohormones]]. They are secreted out of the endocrine cell by exocytosis. Examples include Insulin.

*'''Steroid Hormones''': these lipid soluble hormones are derived from cholesterol. They are synthesised and secreted as needed; there is no capacity for storage. Examples include Cortisol, Androgens and Calcitriol.
