چکیده

An efficient synthesis of buffalo milk pentasaccharide derivative via a 3+2 strategy is described. The use of a trisaccharide isopropyl thioglycoside as a latent glycosyl donor and the application of two well-defined regioselective glycosylations significantly simplified the target preparation.

Study on DGAT1-exon8 Polymorphism in Iranian Buffalo

Objective: Diacylglycerol acyltransferase 1 is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. The objective of this project is to check out the polymorphism at the exon 8 region of DGAT1 gene using PCR-SSCP technique in Iranian water buffaloes (Bubalus bubalis). Recent activities have shown that a significant association between lysine at amino acid positi...

Comparing the Activity and Thermal Inactivation Behavior of Lactoperoxidase in Iranian Cow and Buffalo Milk and Whey

Background: Lactoperoxidase (LPO) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. The aim of this study was to provide information on activity and thermal inactivation behavior of LPO in Iranian cow and buffalo milk and whey. Methods: Sixty cow and buffalo milk samples were collected. The LPO activity was measured using ...

Expedient Synthesis of the Pentasaccharide Repeating Unit of the Polysaccharide O‐Antigen of Escherichia coli O11

A convergent [3+2] block synthetic strategy was developed for the synthesis of the pentasaccharide repeating unit of the cell wall O-antigen of Escherichia coli O11 strain in excellent yield in a minimum number of steps. Several suitably functionalized thioglycoside derivatives were used as glycosyl donors during the synthesis of the target compound. A thioglycoside was the glycosyl donor used ...
