Methionyl-Aspartate
Methionyl-Aspartate is a dipeptide composed of methionine and aspartate. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

3beta-Chlorodehydrocostuslactone
3beta-chlorodehydrocostuslactone belongs to guaianolides and derivatives class of compounds. Those are diterpene lactones with a structure characterized by the presence of a gamma-lactone fused to a guaiane, forming 3,6,9-trimethyl-azuleno[4,5-b]furan-2-one or a derivative. 3beta-chlorodehydrocostuslactone is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 3beta-chlorodehydrocostuslactone can be found in sweet bay, which makes 3beta-chlorodehydrocostuslactone a potential biomarker for the consumption of this food product.
Kinsenoside
(3R)-5-Oxotetrahydro-3-furanyl beta-D-glucopyranoside is a glycoside. Kinsenoside is a natural product found in Anoectochilus formosanus, Anoectochilus koshunensis, and Crocus sativus with data available. Kinsenoside is a main active component isolated from plants of the genus Anoectochilus, and exhibits many biological activities and pharmacological effects[1]. Kinsenoside rescues the nucleus pulposus cells (NPCs) viability under oxidative stress and protects against apoptosis, senescence and mitochondrial dysfunction in a Nrf2-dependent way[2].
