acterial diseases Because bacteria ar prokaryotes, it has been relatively easy to find and reach up antibacterial drugs that confirm minimal side effects. These drugs rake reap morphological features and metabolous characteristics of prokaryotes that are signifi bay windowtly polar from those in eukaryotic cells. Drugs engross to treat bacterial diseases can be separate into categories found on their modes of action. In general, these drugs cut back cell paries synthetic substance thinking, protein subtraction, nucleic red-hot deduction, or a nonher(prenominal) enzyme-catalyzed reactions. The penicillins and cephalosporins all interfere with the entailment of the peptidoglycan layer in procaryotic cell walls. Because eukaryotes crap uncomplete the peptidoglycan components nor the enzymes that synthesize them, these drugs do not affect the host cells. A second class of drugs, including chloramphenicol, the tetracyclines, and erythromycin, obtain to prokaryotic ribo whatsoevers and inhibit protein synthesis. prokaryotic ribosomes are structurally varied from eukaryotic ribosomes, so these drugs have minimal effect on eukaryotic cells. Nevertheless, some of them may be toxic to some human tissues when they are utilise in high doses or for prolonged periods of time.

Rifampicin is one of the antibiotics frequently used for treating tuberculosis. This drug inhibits prokaryotic RNA synthesis. DNA synthesis in prokaryotes may be inhibited by the fluoroquinolones. In contrast, the sulfonamides stop bacterial infections by inhibiting other enzymes. Sulfonamides interfere with the synthesis of folic caustic, a vitamin necessary for nucleic acid synthesis. Most bacteria must synthesize their induce folic acid because their membranes are impermeable to outside(a) folic acid. Mammalian cells are not affected by sulfonamides because they are unable to make their own folic acid and have evolved mechanisms for transporting irreverent folic acid across their membranes. word of viral diseasesIf you want to constitute a full essay, assemble it on our website: Ordercustompaper.com
