Monosaccaridi

N-acetyl-D-glucosamine is a regiospecific and stereoselective hydrochloride of D-glucosamine. It is used as a building block for the synthesis of peptides, proteins, and other biological molecules. N-Acetyl-D-glucosamine is synthesized by reacting ethylene diamine with trifluoroacetic acid in the presence of hydrochloric acid. The proton at C2 in the NMR spectrum was found to be diagnostic for the compound. Solid phase microextraction (SPME) was used to extract this compound from a mixture of many components, and it was then analyzed using magnetic resonance spectroscopy (NMR).

B-Estradiol 3-(β-D-glucuronide) sodium salt is a conjugate of estradiol and glucuronic acid. Estrogens are hormones that regulate the development and maintenance of female external genitalia, secondary sexual characteristics, and reproductive function. B-Estradiol 3-(β-D-glucuronide) sodium salt is a metabolite of estradiol. It has been shown to be effective in wastewater treatment plants for the removal of estrogenic compounds from wastewater. This compound has also been validated for monitoring 17β-estradiol with high sensitivity and specificity. The enhanced detection limit of this compound can be used to monitor estrone levels in environmental samples.
