Researchers make bombshell discovery of an entirely new kind of biomolecule

Date Time Researchers make ‘bombshell’ discovery of an entirely new kind of biomolecule A newfound biomolecule, consisting of RNA modified by sugars, could be present in all forms of life and might contribute to autoimmune disease. By Holly Alyssa MacCormick Stanford researchers have discovered a new kind of biomolecule that could play a significant role in the biology of all living things. The novel biomolecule, dubbed glycoRNA, is a small ribbon of ribonucleic acid (RNA) with sugar molecules, called glycans, dangling from it. Up until now, the only kinds of similarly sugar-decorated biomolecules known to science were fats (lipids) and proteins. These glycolipids and glycoproteins appear ubiquitously in and on animal, plant and microbial cells, contributing to a wide range of processes essential for life.
