Physical and chemical studies on ceruloplasmin. V. Metabolic studies on sialic acid-free ceruloplasmin in vivo.
Injection into rabbits of radioactive ceruloplasmin from which sialic acid had been removed enzymatically resulted in a rapid disappearance of the asialoceruloplasmin from the seruni and its appearance in parenchymal cells, but not in Kupffer cells, of the liver. The rapidity of this transfer was dependent upon the presence of intact galactose residues as the terminal, nonreducing sugar of the ...
متن کاملPhysical and Chemical Studies on Ceruloplasmin. Ii. Molecular Oxygen and the Blue Color of Ceruloplasmin.
In their description of the isolation and properties of ceruloplasmin, Holmberg and Laurel1 (1) noted that this intensely blue copper-protein could be decolorized by reducing agents such as ascorbic acid. Although the decoloriaation was “. . . completely reversible in the presence of oxygen, attempts to (restore blue color by oxidation) with potassium ferricyanide were not successful.” They won...

متن کاملPhysical and chemical studies on ceruloplasmin. IV. Preparation of radioactive, sialic acid-free ceruloplasmin labeled with tritium on terminal D-galactose residues.
Ceruloplasmin, a normally occurring plasma protein containing copper and carbohydrate as integral parts of its molecule, appears to play some role in maintaining the normal, near zero balance of body copper (1). However, despite considerable experimental effort, little definitive information is currently available concerning either this role or the metabolism of the protein. The present investi...
متن کاملFirst-principles Studies on Physical and Chemical Properties of Nanostructures
The physical and chemical properties of decorated graphene and graphene ribbons, single-layer III-V systems, three-dimensional carbon and BN foam, and transition-metal-molecular sandwich nanowires have been investigated by first-principle calculations and their potential applications have been predicted. First, it is shown that zigzag graphene nanoribbons (ZGNRs) can be converted into half meta...
