Glycopeptides are amino acid molecules containing a carbohydrate called glucan, playing a crucial biological role in maintaining good health and preventing disease. Glycobiology studies the molecular structure and function of glycopeptides to produce treatments and therapies that improve health and prolong life, including glycopeptide antibiotics used to combat certain forms of bacteria that are resistant to common forms of treatment. These drugs are administered through intravenous therapy or orally and should be taken to completion to avoid the infection coming back stronger.
Peptides, which are amino acid molecules, that contain a carbohydrate called glucan are called glycopeptides. Due to the ubiquity of glycans in the cells of all living organisms and the role that glycopeptides play in maintaining good health and preventing disease, the field of glycobiology has emerged to study these molecules. In addition, glycopeptide antibiotics have been developed to treat certain types of infection.
Glycopeptides are produced through the process of peptide synthesis. During this process, glycans are attached to peptides and linked with other glycan-bound amino acids until a chain is produced. The newly created peptides are subsequently linked with proteins and lipids through glycosylation. This enzymatic process allows glycopeptides to influence biochemical communication between cells. Consequently, these peptides play a crucial biological role during the life of an organism; Cells create skin and organ tissue, fight disease, and help the body maintain homeostasis.
Glycobiology seeks to identify the molecular structure of glycopeptides and to further explore the function of these peptides in relation to other cells and molecules in the body. By determining how glycopeptides are structured and better understanding how they work, people working in the field of glycobiology can produce treatments and therapies that improve health and prolong life. For example, glycopeptides contain qualities that must be broken down before cancer cells can spread; Knowledge of glycopeptide structures could allow scientists to create a remedy or treatment that prevents glycopeptide breakdown and inhibits the spread of cancer cells.
Glycopeptide antibiotics are a class of antibiotics developed to combat certain forms of bacteria that have proven resistant to more common forms of treatment such as penicillin. Vancomycin is a commonly prescribed antibiotic from this class of drugs. It is used to cure inflammation of the intestine. This disease usually results from harmful bacteria in the intestines; Vancomycin kills bacteria. Glycopeptide-derived antibiotics are ineffective against viral infections.
These drugs are usually administered directly into the veins through intravenous therapy or, in the case of intestinal infections, taken orally through a pill. Since glycopeptide-based drugs are generally considered a treatment of last resort for resistant strains of bacteria, a course should be taken to completion, even if the patient begins to feel better. Otherwise, the infection may come back stronger and be more difficult to treat. Glycopeptide antibiotics are not without their side effects. If given in high doses, this medication may cause a rash or interfere with breathing by causing muscle tension in the respiratory muscles.
