3-Bromotyrosine
3-Bromotyrosine(BY) is generated from the halogenation of tyrosine residues in plasma proteins via the enzyme Eosinophil peroxidase. The presence of free bromotyrosine in blood or urine is the result of enzymatic degradation of these brominated proteins. A significantly higher concentration of BY was observed in the urine from asthmatic patients than in that from healthy control subjects (PMID: 15196282). Bromotyrosine may be useful for monitoring the activation of eosinophils in asthmatic patients. 3-Bromotyrosine(BY) is generated from the halogenation of tyrosine residues in plasma proteins via the enzyme Eosinophil peroxidase.

1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate
1-hydroxy-2-methyl-2-(e)-butenyl 4-diphosphate is soluble (in water) and a moderately acidic compound (based on its pKa). 1-hydroxy-2-methyl-2-(e)-butenyl 4-diphosphate can be found in a number of food items such as butternut, pigeon pea, saskatoon berry, and ostrich fern, which makes 1-hydroxy-2-methyl-2-(e)-butenyl 4-diphosphate a potential biomarker for the consumption of these food products.
