Amines, such as [[norepinephrine]], [[epinephrine]], and [[dopamine]] ([[catecholamines]]), are derived from single [[amino acid]]s, in this case tyrosine. [[Thyroid]] hormones such as [[Triiodothyronine|3,5,3'-triiodothyronine]] (T3) and [[Levothyroxine|3,5,3',5'-tetraiodothyronine]] (thyroxine, T4) make up a subset of this class because they derive from the combination of two iodinated tyrosine amino acid residues.<ref>{{Cite journal |last1=Carvalho |first1=Denise P. |last2=Dupuy |first2=Corinne |date=2017-12-15 |title=Thyroid hormone biosynthesis and release |url=https://www.sciencedirect.com/science/article/pii/S0303720717300515 |journal=Molecular and Cellular Endocrinology |series=A century of thyroid hormone research - Vol. I: The expanded thyroid hormone network: novel metabolites and modes of action |volume=458 |pages=6–15 |doi=10.1016/j.mce.2017.01.038 |pmid=28153798 |s2cid=31150531 |issn=0303-7207}}</ref>
