Toward the Synthesis of 3,3‐Difluoro Deaminated Sialic Acid (C3DFKDN)

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The synthesis of protected C3‐difluoro KDN (C3DFKDN), an unnatural derivative of the sialic acid member, KDN, and key building block for KDN‐based chemical probes, is reported. Its 12‐step synthetic route starts from commercially available methyl d‐mannopyranoside and key steps include a Reformatsky reaction with ethyl bromodifluoroacetate, alkylation ...

Self‐Emulsifying Biocatalysis Based on an Amphipathic Protein BslA‐Modified Esterase Functioning as a Fine‐Tuned System for Oil Hydrolysis

open access: yesFood Bioengineering, EarlyView.
BslA is a promising tool to create an robust self‐emulsifying biocatalysis platform by reducing the droplet sizes of emulsion and improving its stability. It could guarantee the efficient hydrolysis of astaxanthin esters catalyzed by Est3‐14 without extra emusifier, increasing the yield of free astaxanthin to 184 μg·mL−1.
