Used in microbiological and biochemical research as a carbon source for bacterial growth studies. Commonly employed in cell culture media to support the growth of specific microorganisms that metabolize rhamnose. Serves as a marker in metabolic pathway analysis due to its unique utilization pathway in certain bacteria. Applied in the synthesis of complex carbohydrates and glycoconjugates for pharmaceutical development. Also utilized in studies involving gene expression regulation, particularly in systems where rhamnose-inducible promoters are used to control protein production.
