5-Hydroxylysine is an amino acid with the molecular formula C6H14N2O3. It was first discovered in 1921 by Donald Van Slyke.[1] It is a hydroxy derivative of lysine. It is most widely known as a component of collagen.[2]

It is biosynthesized from lysine via oxidation by lysyl hydroxylase enzymes. The most common form is the (5R) stereoisomer found in collagen. However, JMJD6 has recently been shown to be a lysyl hydroxylase which modifies an RNA splicing factor producing the (5S) stereoisomer.
