(S,S)-(+)-Ethambutol is powerful and selective antitubercular drug.It is a typical example of an old drug that was introduced for clinical use in its unichiral form. . Ethambutol contains two constitutionally symmetrical chiral centers in its structure and exists in three stereoisomeric forms, the enantiomeric pair (+)-(S,S)- and (−)-(R,R)-ethambutol, along with the achiral stereoisomer called m
Ethambutol enantiomers The antitubercular agent Ethambutol contains two constitutionally symmetrical stereogenic centers in its structure and exists in three stereoisomeric forms. An enantiomeric pair (S,S)- and (R,R)-ethambutol, along with the achiral stereoisomer called meso -form, it holds a diastereomeric relationship with the optically ...
In 1848, Louis Pasteur became the first scientist to discover chirality and enantiomers while he was working with tartaric acid. During the experiments, he noticed that there were two crystal structures produced but these structures looked to be non-superimposable mirror images of each other; this observation of isomers that were non-superimposable mirror images became known as enantiomers.
Non-plumped chicken generally contains 45 to 70 mg per serving. [8] In January 2010, the American Heart Association released new guidelines calling for all Americans to reduce their sodium intake to 1,500 mg (equivalent to 3.8 g of salt) from 2,300 mg. Previously, 1,500 mg was the recommended limit for higher-risk individuals only. [ 9 ]
Reduce the heat to low and add the processed cheese, tomatoes and green chiles, and chile powder. Cook, stirring constantly, until the cheese melts and the dip is smooth and combined, 2 to 3 ...
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.

SEM image of a grain of table salt. The health effects of salt are the conditions associated with the consumption of either too much or too little salt. Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are ...
