Antibiotics are drugs that inhibit bacterial growth, often by targeting structures like ribosomes, involved in protein synthesis. Ribosomes, present in all living cells, are complex structures composed of rRNAs and proteins responsible for creating proteins.
Antibiotics are compounds that inhibit the growth of bacteria. They function by targeting certain structures and processes in bacterial cells, such as the ribosomes, while typically having minimal or no effect on human (eukaryotic) cells. Some antibiotics function by binding to the 30S subunit of bacterial ribosomes, such as aminoglycosides and tetracyclines, disrupting protein synthesis and thereby inhibiting bacterial cell growth.
Ribosomes are complex macromolecules that are responsible for protein synthesis in cells. They are composed of catalytic ribosomal RNAs (rRNAs) and many distinct polypeptides.
Prokaryotes (like bacteria) have 70S ribosomes, while eukaryotes (like humans) have 80S ribosomes in the cytoplasm and rough endoplasmic reticulum, and 70S ribosomes in mitochondria and chloroplasts. Specific antibiotics target the bacterial (prokaryotic) ribosomes and disrupt their function, which is essential for the survival of the bacteria.
