Mucin proteins are essential for life but are challenging to study due to their complex glycosylation patterns. Synthetic mimics have become vital tools for understanding and modulating the roles of mucins in human health and disease. These materials also have diverse biomedical applications as lubricants and anti-

Lipopolysaccharides (LPSs) isolated from marine bacteria represent a valuable resource for biomedical innovation. Here, we report the first structural elucidation of the lipid A moiety and a preliminary immunological assessment of the full LPS from the marine Gram-negative Rheinheimera japonica KMM 9513T.
