p-Cresol sulfate

Sulfuric acid, mono(4-methylphenyl) ester

C7H8O4S (188.0143288)

p-Cresol sulfate is a microbial metabolite that is found in urine and likely derives from secondary metabolism of p-cresol. It appears to be elevated in the urine of individuals with progressive multiple sclerosis (PMID:10775436). p-Cresol sulfate is the major component of urinary MBPLM (myelin basic protein-like material). p-Cresol sulfate is a small protein-bound molecule that is poorly cleared with dialysis. It has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID:22626821). Uremic toxins include other low-molecular-weight compounds such as indoxyl sulfate, 3-carboxy-4-methyl-5-propyl-2-furanpropionic acid, and asymmetric dimethylarginine (PMID:18941347). It has also been linked to cardiovascular disease and oxidative injury. Higher levels are associated with overgrowth of intestinal bacteria from Clostridia species, including C. difficile. p-Cresol is generated by the partial breakdown of tyrosine and phenylalanine by a wide range of intestinal obligate or facultative anaerobes, including the genera Bacteroides, Lactobacillus, Enterobacter, Bifidobacterium, and especially Clostridium (PMID:2394806). p-Cresol sulfate is a microbial metabolite that is found in urine and likely derives from secondary metabolism of p-cresol.

Perflutren

1,1,1,2,2,3,3,3-Octafluoropropane

C3F8 (187.9872256)

Perflutren, a diagnostic drug that is intended to be used for contrast enhancement during the indicated echocardiographic procedures, is comprised of lipid-coated microspheres filled with octafluoropropane(OFP) gas. When exposed to ultrasound waves, the microspheres resonate and echo strong signals back to the ultrasound machine. The difference in density between the gas-filled bubbles and the blood around them creates an increased level of contrast visible in the resulting ultrasound image. During echocardiography, activated Perflutren enhances images of the inner edges or borders of the heart, producing an improved image that may enable physicians to better diagnose patients. Perflutren, a diagnostic drug that is intended to be used for contrast enhancement during the indicated echocardiographic procedures, comprised of lipid-coated microspheres filled with octafluoropropane(OFP) gas. It provide contrast enhancement of the endocardial borders during echocardiography. The perflutren lipid microspheres exhibit lower acoustic impedance than blood and enhance the intrinsic backscatter of blood. Albumin is found in brazil nut, common wheat, and ginger.

Calcium tartrate

(R*,r*)-(+-)-2,3-dihydroxybutanedioic acid, monoammonium monosodium salt

C4H4CaO6 (187.9633794)

Calcium tartrate is also known as mn(iii) tartrate or tartaric acid, calcium salt, (r-r*,r*)-isomer. Calcium tartrate is soluble (in water) and a moderately acidic compound (based on its pKa). Calcium tartrate can be found in tamarind, which makes calcium tartrate a potential biomarker for the consumption of this food product. Calcium tartrate is a byproduct of the wine industry, prepared from wine fermentation dregs. It is the calcium salt of tartaric acid, an acid most commonly found in grapes. Its solubility decreases with lower temperature, which results in the forming of whitish (in red wine often reddish) crystalline clusters as it precipitates. It finds use as a food preservative and acidity regulator. Like tartaric acid, calcium tartrate has two asymmetric carbons, hence it has two chiral isomers and a non-chiral isomer (meso-form). Most calcium tartrate of biological origin is the chiral levorotatory (‚Äì) isomer . Calcium tartrate is also known as mn(iii) tartrate or tartaric acid, calcium salt, (r-r*,r*)-isomer.
