Antimicrobial peptides are small, naturally occurring molecules that are produced by various organisms as a defense mechanism against pathogens. These peptides are capable of disrupting the membranes of bacteria, fungi, viruses, and parasites, leading to their destruction. Antimicrobial peptides have gained significant attention in recent years as potential alternatives to traditional antibiotics, as they have shown promise in combating drug-resistant pathogens. Researchers are studying the structure, function, and mechanism of action of these peptides to better understand their potential applications in the treatment of infectious diseases.
