N-Acetyl-L-tryptophan is an endogenous metabolite.

(R)-3-Hydroxybutanoic acid sodium ((R)-3-Hydroxybutyric acid) is a metabolite, and converted from acetoacetic acid catalyzed by 3-hydroxybutyrate dehydrogenase. (R)-3-Hydroxybutanoic acid sodium has applications as a nutrition source and as a precursor for vitamins, antibiotics and pheromones.

Naringinase, a hydrolytic enzymatic complex, possesses the activity of both α-L-rhamnosidase and β-D-glucosidase. Naringinase has wide occurrence in nature. Naringinase can be used in the biotransformation of steroids, antibiotics, and mainly on glycosides hydrolysis.

Spirapril (SCH 33844) hydrochloride is a potent angiotensin converting enzyme (ACE) inhibitor with antihypertensive activity. Spirapril competitively binds to ACE and prevents the conversion of angiotensin I to angiotensin II. Spirapril is an orally active prodrug of Spiraprilat and can be used for the research of hypertension, congestive heart failure.

Cholera toxin (Choleragen), an AB(5)-subunit toxin, enters host cells by binding the ganglioside GM1 at the plasma membrane (PM) and travels retrograde through the trans-Golgi Network into the endoplasmic reticulum (ER). Choleragen activates adenylate cyclase by catalyzing ADP-ribosylation of Gs alpha, the stimulatory guanine nucleotide-binding protein.

2,6-Dibromophenol is an endogenous metabolite.

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.

3,4-Dimethoxyphenethylamine is an endogenous metabolite.

4-Pentenoic acid is an endogenous metabolite.

D-Tyrosine is the D-isomer of tyrosine. D-Tyrosine negatively regulates melanin synthesis by inhibiting tyrosinase activity. D-Tyrosine inhibits biofilm formation and trigger the self-dispersal of biofilms without suppressing bacterial growth.

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.
