Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. Introducing a new discovery about 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, Application In Synthesis of N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide.
A method is presented for the isolation of a lectin from a Japanese cultivar of Phaseolus vulgaris seed by an affinity chromatography on the heat-denaturated porcine thyroglobulin-Sepharose.The lectin is a glycoprotein whose molecular weight is 120,000; it consists of four apparently identical subunits, held together by non-covalent forces.The isoelectric point is 5.5 and the sedimentation constant is 6.66 S at pH 5.3.The lectin is nonspecific in agglutination for any types of human erythrocytes.The lectin induces mitosis in human lymphocytes at concentration between 10 and 100 mug per 3E6 lymphocytes.The hemagglutinating and mitogenic activities are inhibited by N-acetyl-D-galactosamine and some simple sugars.
