Detailed Solution
On the basis of chemical nature, hormones are classified as steroid hormones, peptide (protein) hormones and amine hormones.
Thyroxine and adrenaline are amine hormones. Thyroxine is an iodine containing derivative of the amino acid tyrosine and is secreted by the thyroid gland.
Amine hormones are water soluble hormones having amino groups.
Insulin is a peptide (protein) hormone made of 51 amino acids.
Progesterone is a steroid hormone.
Oxypurin (oxypurine) is a purine derivative, not an amine hormone.
So the amine hormone among these is thyroxine.
