Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside .
Neomycin is an aminoglycoside antibiotic that displays bactericidal activity against Gram-negative aerobic bacilli and some anaerobic bacilli where resistance has not yet arisen. It is generally not effective against Gram-positive bacilli and anaerobic Gram-negative bacilli. Neomycin comes in oral and topical formulations, including creams ...
Although various definitions of acids and bases are used in chemistry, the only one that is useful for chemistry in aqueous solution is that of Brønsted: [37] [38] an acid is a species that can donate a proton to another species, and a base is one that can accept a proton. This criterion is used to label the groups in the above illustration.
Side-effects of amikacin are similar to those of other aminoglycosides. Kidney damage and ototoxicity (which can lead to hearing loss) are the most important effects, occurring in 1–10% of users. [17] The nephro- and ototoxicity are thought to be due to aminoglycosides' tendency to accumulate in the kidneys and inner ear. [8] Diagram of the ...

This pocket is largely composed of negatively charged amino acid residues, which stabilize the positive charge of and orient the substrate in the active site. Additionally, this pocket is thought to contribute to the promiscuity of the enzyme, allowing it to take in and stabilize several different kinds of aminoglycosides. [6]
Glycolic acid (or hydroxyacetic acid; chemical formula HOCH 2 CO 2 H) is a colorless, odorless and hygroscopic crystalline solid, highly soluble in water. It is used in various skin-care products. Glycolic acid is widespread in nature. A glycolate (sometimes spelled "glycollate") is a salt or ester of glycolic acid.
The aminocyclitol family of natural products is a class of sugar-derived microbial secondary metabolites that demonstrate significant biological activities. Aminocyclitols are found as a component of aminoglycoside antibiotics which is also called as pseudosugars or pseudosaccharides.
