Galactosylhydroxylysine is a component of bone collagen produced by post-translational glycosylation of hydroxylysine. Galactosylhydroxylysine is released during bone resorption and has been shown to be elevated in metabolic bone loss[1].
ChEBI: 5-(beta-D-galactosyloxy)-L-lysine is a 5-glycosyloxy-L-lysine in which the glycosyl fragment is specified as beta-D-galactose.
