Uncovering a Novel Molecular Mechanism for Scavenging Sialic Acids in Bacteria

Homonuclear 2D 1H,1H COSY and 1H,1H TOCSY experiments showed connectivity of this proton to one and two other protons, respectively (Fig. S2). Signal 2, at 2.73 ppm, corresponds then to a proton neighboring a carbonyl on one side and at least two other protons on the other side with chemical shifts in the 3-4 ppm region. If you have any questions regarding where and ways to utilize sialic acid manufacturers, you can contact us at our website. Analysis of the 3-4 ppm spectral region, where standard sugar-ring C-H signals typically show, suggests that the intermediate chemical shifts are closer to Neu5Ac than to 2,7-anhydro-Neu5Ac (Fig. S3).
