WE describe here a sugar and amino acid transport protein that has been isolated from a cell for the first time. It is a homogeneous protein subunit from the mucosai brush border of hamster jejunum that is involved in the Na+-dependent binding of activel
Low-molecular-weight metabolites of d-[1-14C]glucosamine in cultured, normal and carcinomatous, human-mammary cells 被引量: 0发表: 1982年 A complex of two cell surface glycoproteins from ascites mammary adenocarcinoma cells The major cell surface sialoglycoprotein (ASGP-1) of 13762 rat ascites ...
Moles and Molecular Weight: Definitions A moleis equivalent to 6.023×1023molecules. That molecule may be a pure elemental atom or a molecule consisting of a bound collection of atoms. For example, a mole of hydrogen is equivalent to 6.023×1023molecules of hydrogen. A mole of glucose (C6H12O6...
Dideoxysugars, which display biological activities ranging from mediating cell-cell interactions to serving as components in some antibiotics, are synthesized in various organisms via complex biochemical pathways that begin with the attachment of α-d-glucose 1-phosphate to either CTP or dTTP. Here we...
(b) Eight sheep fed freely on lucerne hay were given increasing amounts of whole wheat up to the limit of appetite, either as a single daily feed or at 6-h intervals. Usually in the course of adaptation the rumen pH fell, there was transient appearance of glucose in the rumen fluid, ...
Not only are low molecular weight amines abundantly distributed in nature, but numerous drugs, synthetic probes and other molecules of interest also contain amino groups. The sensitive detection, identification and quantitation of amines...
the geometric arrangement of chemical groups inside the ligand-binding pocket does not seem to be sufficient to explain the selective activation of this receptor by onlyd-fructose. We therefore determined the structure of BmGr9 in a third gating state bound to a non-activating sugar,l-sorbose,...
The samples showed a large variation in both the content of extractable beta-glucan (0.76-3.68%) and the average molecular weight ((1.25-1.78) x 10(6) g mol(-1)). An analysis of the variance of beta-glucan content and the molecular weight of Swedish oat samples grown in 2000 and ...
