Epinephrine is an amino acid derived hormone while progesterone, prostaglandin and estrogen are steroidal hormone. Related Theory According to Chemical Nature, hormone are of 5 types: (a) Steroid Hormones: e.g., Testosterone, Oestrogen, Progesterone etc. (b) Amine Hormones: e.g., TyTf epinephrine, norepinephrine. (c) Peptide Hormones: e.g., Oxytocin and vasopressin both consist of only 9-amino acid residues only. (d) Protein Hormones: e.g., Insulin, glucagon, STH etc. (e) Glycoprotein Hormones: LH, FSH, TSH etc. (f) Eicosanoids Hormones: (small fatty acid derivatives) e.g., Prostaglandins.
