The structure of lipid A from lipopolysaccharide of Phyllobacterium trifolii PETP02T, a nitrogen-fixing symbiotic bacterium, was studied. It was found that the lipid A backbone was composed of two 2,3-diamino-2,3-dideoxy-d-glucose (GlcpN3N) residues connected by a β-(1 → 6) glycosidic linkage, substituted by galacturonic acid (GalpA) at position C-1 and partly decorated by a phosphate residue at C-4′ of the non-reducing GlcpN3N. Both diaminosugars were symmetrically substituted by 3-hydroxy… Expand

Collagen peptides isolated from Salmon salar and Tilapia nilotica skin accelerate wound healing by altering cutaneous microbiome colonization via up-regulated NOD2 and BD14.
These studies show that collagen peptide could up-regulate wound NOD2 and BD14, which were implicated in microflora colonization regulation in the wound tissue and promoted wound healing by controlling inflammatory reaction and increasing wound angiogenesis and collagen deposition. Expand
