Plasma amino acid derivatives and nucleosides

1. Longevity Relatives Count score is associated with plasma amino acid derivatives and nucleosides in humans.

   “High LRC scoring individuals exhibited lower levels of amino acid derivatives (prolylhydroxyproline, 5-hydroxy-tryptophan, asymmetric dimethylarginine), nucleosides (2-methylguanosine, 7-methylguanosine, pseudouridine)”
