Heat capacity changes in carbohydrates and protein-carbohydrate complexes.
Carbohydrates are crucial for living cells, playing myriads of functional roles that range from being structural or energy-storage devices to molecular labels that, through non-covalent interaction with proteins, impart exquisite selectivity in processes such as molecular trafficking and cellular recognition. The molecular bases that govern the recognition between carbohydrates and proteins hav...
متن کاملElevation of serum protein-bound carbohydrates and haptoglobin in schizophrenia.
The mean concentration of each of the serum protein-bound carbohydrates (hexose, hexosamine, fucose, and sialic acid) was significantly elevated in a group of 60 male schizophrenic patients. The total serum protein was elevated, ceruloplasmin was normal, and C-reactive protein was absent. Serum haptoglobin was significantly elevated. The distribution of haptoglobin types was normal. Haptoglobin...
متن کاملNonstatistical binding of a protein to clustered carbohydrates.
Carbohydrate-derivatized self-assembled monolayers (SAMs) are used as a model system to address issues involving cell-surface carbohydrate-protein interactions. Here we examine the influence of carbohydrate surface density on protein-binding avidity. We show that the binding selectivity of Bauhinia purpurea lectin switches from one carbohydrate ligand to another as the surface density of the ca...
متن کاملThe protein-bound carbohydrates of seromucoid from normal human serum.
The neutral sugars and hexosamines in the seromucoid fraction of normal human serum were identified and determined simultaneously by gas-liquid chromatography of their aldononitrile acetates. Besides the sialic acid, normal seromucoid contained fucose, arabinose, mannose, glucose, galactose, glucosamine and galactosamine. The presence of arabinose and glucose, not previously reported in seromuc...
متن کاملIdentification of protein-bound carbohydrates by mass spectrometry.
This review outlines the use of modern methods of mass spectrometry, mainly based on electrospray ionization and matrix-assisted lased desorption/ionization, for the identification of protein-bound carbohydrates. The techniques are briefly described together with methods for glycan release and purification prior to mass spectrometry. Fragmentation of glycans, produced under various conditions, ...
