Marine Glycoconjugates: Natural Products from Marine Fungi

Rather Ahmad

Glycoconjugates are utilised in medicine, such as vaccinations, and have important functions in biological systems. Cellular contacts, such as cell-cell recognition and the binding of cells to the intercellular matrix, are mediated by glycoproteins, peptidoglycans, lipopolysaccharides, and other biopolymer glycoconjugates. These molecules carry out signalling, antigenic, and transport duties and take role in the synthesis of receptors and other crucial blood and membrane components. They are essential for preserving the physical condition of connective tissue due to the negative charges on some sulfated glycoconjugates and the binding of water. Low molecular weight glycoconjugates, including glycolipids and triterpene and steroidal glycosides, are also widely known as compounds with significant internal and external functions. A wide range of biological actions, including protective, cytotoxic, anticancer, immunomodulatory, and antioxidant capabilities, are displayed by various glycoconjugates. For signal or anti-predatory exometabolites of marine species to be highly soluble in water, carbohydrate moieties must have this ability. The extremely large variety of glycoconjugates of marine origin, including those given in the current Special Issue, is explained by all these features.
