Hydroxyacetone is an endogenous metabolite.

Dimethyl sulfone is an endogenous metabolite.

Diphenyl disulfide is an endogenous metabolite.

Monomethyl phthalate is a phthalate metabolite. Monomethyl phthalate acts as a urinary biomarker of phthalates exposure and can be used as a standard for the determination of thyroid cancer and benign nodule.

Methoxyacetic acid is an endogenous metabolite.

3,4-Dimethoxyphenethylamine is an endogenous metabolite.

4-Pentenoic acid is an endogenous metabolite.

2-Methylbenzaldehyde is an endogenous metabolite.

D-Leucine is a more potent anti-seizure agent than L-leucine. D-leucine potently terminates seizures even after the onset of seizure activity. D-leucine, but not L-leucine, reduces long-term potentiation but had no effect on basal synaptic transmission in vitro.
