Are carbohydrates a quaternary structure

No, carbohydrates do not have a quaternary structure. Quaternary structure refers to the arrangement of multiple polypeptide chains in proteins. Carbohydrates are organic compounds made of sugar molecules and are classified based on their structure as monosaccharides, disaccharides, oligosaccharides, and polysaccharides, but they do not exhibit a quaternary structure like proteins do.
