Most roe samples demonstrated low levels of 4-hydroxybutyric acid, from 0.31 mg/g in roe of female crab Charybdis natator (CNF) up to 1.5 mg/g in red caviar (RCV)
Most human tissues can convert trimethyllysines to -butyrobetaine (the compound prior to carnitine) but only the liver, kidney, brain, and testes express the -butyrobetaine dioxygenase enzyme that hydroxylates -butyrobetaine forming carnitine
However, the field still faces significant challenges, such as data heterogeneity, poor algorithm interpretability, and issues with clinical translation efficiency
