Nitrofurantoin
A bacteriostatic or bactericidal agent depending on the concentration and susceptibility of the infecting organism. Nitrofurantoin is active against some gram positive organisms such as S. aureus, S. epidermidis, S. saprophyticus, Enterococcus faecalis, S. agalactiae, group D streptococci, viridians streptococci and Corynebacterium. Its spectrum of activity against gram negative organisms includes E. coli, Enterobacter, Neisseria, Salmonella and Shigella. It may be used as an alternative to trimethoprim/sulfamethoxazole for treating urinary tract infections though it may be less effective at eradicating vaginal bacteria. May also be used in females as prophylaxis against recurrent cystitis related to coitus. Nitrofurantoin is highly stable to the development of bacterial resistance, a property thought to be due to its multiplicity of mechanisms of action.

D-Erythro-imidazole-glycerol-phosphate
D-Erythro-imidazole-glycerol-phosphate belongs to the class of organic compounds known as monoalkyl phosphates. These are organic compounds containing a phosphate group that is linked to exactly one alkyl chain. D-Erythro-imidazole-glycerol-phosphate is a very strong basic compound (based on its pKa). Outside of the human body, D-erythro-imidazole-glycerol-phosphate has been detected, but not quantified in, several different foods, such as mammee apples, scarlet beans, grass pea, olives, and bog bilberries. This could make D-erythro-imidazole-glycerol-phosphate a potential biomarker for the consumption of these foods. D-Erythro-imidazole-glycerol-phosphate is an intermediate in histidine metabolism. It is a substrate for imidazoleglycerol-phosphate dehydratase (hisB) and can be generated from phosphoribulosylformimino-AICAR-P. D-Erythro-imidazole-glycerol-phosphate is an intermediate in Histidine metabolism. It is a substrate for imidazoleglycerol-phosphate dehydratase (hisB) and can be generated from Phosphoribulosyl-formimino-AICAR-phosphate then it is converted to Imidazole-acetol phosphate. [HMDB]. D-Erythro-imidazole-glycerol-phosphate is found in many foods, some of which are buffalo currant, fruits, hyacinth bean, and small-leaf linden.

Uranium
U (238.050786)
Uranium, also known as 92u or uran, is a member of the class of compounds known as homogeneous actinide compounds. Homogeneous actinide compounds are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Uranium can be found in a number of food items such as common hazelnut, soft-necked garlic, sunburst squash (pattypan squash), and red beetroot, which makes uranium a potential biomarker for the consumption of these food products. Uranium is formally rated as a carcinogenic (IARC 1) potentially toxic compound. Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 is the only naturally occurring fissile isotope, which makes it widely used in nuclear power plants and nuclear weapons. However, because of the tiny amounts found in nature, uranium needs to undergo enrichment so that enough uranium-235 is present. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. Uranium-238 has a small probability for spontaneous fission or even induced fission with fast neutrons; uranium-235 and to a lesser degree uranium-233 have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained nuclear chain reaction. This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons. Depleted uranium (238U) is used in kinetic energy penetrators and armor plating. Uranium is used as a colorant in uranium glass, producing lemon yellow to green colors. Uranium glass fluoresces green in ultraviolet light. It was also used for tinting and shading in early photography .
