5-hydroxy-1-tetralone as the fluorescent labeling reagent.

1-Hydroxypyrene (1-Pyrenol), a biomarker of exposure to polycyclic aromatic hydrocarbons, is analyzed in urine samples.

3-Furanoic acid (3-Carboxyfuran) is an organic acid regularly occurring in the urine of healthy individuals. 3-Furanoic acid (3-Carboxyfuran) is also a compound found in honey and honeydew samples.

Acid red 88 is an anionic dye with potentially useful photocatalytic research applications. Acid red 88 has been used to determine the effect of Au deposition on ZnO photocatalytic activity under visible light. Additionally, the photocatalyst Au-TiO2 was

Acetyl-L-lysine (Nα-Acetyl-L-lysine) is a N-acetylated amino acid. It is a normal constituent of human urine with concentrations in normal samples too small to allow its routine detection; however, it has been found at increased levels in the urine of a patient with aminoacylase I deficiency.

Blood group A antigen tetraose type 5 (A-Tetrasaccharide), a tetrasaccharide specific to blood group A, inhibits the binding of anti-A antibody to blood group A substance and can be isolated from polar bear milk samples [1] [2].

N-Cholyl-L-leucine is a bile acid amidate. It has been found in fecal samples from extremely premature infants with mild or severe brain injuries. N-Cholyl-L-leucine has been used as a standard for the detection of endogenous bile acid amidates in human plasma and fecal samples.

N-Cholyl-L-alanine is a bile acid amide identified in human fecal samples.
