Chemical synthesis of 1-O-alkyl and 1-O-acyl dihydroxyacetone-3-phosphate
(Elsevier, 1983-08)
A method for the chemical synthesis of 1-O-hexadecyl dihydroxyacetone-3-phosphate is described. The synthesis was started with the preparation of O-hexadecyl glycolic acid by condensing 1-iodohexadecane with ethyl glycolate ...
Immunochemical studies on the combining site of the blood group A-special lima bean lectin
(Elsevier, 1986-08-15)
The combining site of the lima bean (Phaseolus lunatus) lectin (LBL) was studied by quantitative precipitin and precipitin-inhibition assays. The lectin precipitated best with hog gastric mucosa and human ovarian cyst blood ...
Calorimetric studies of the polynucleotide analog poly(−)2-[2-(thymin-1-yl) propanamido]propenoic acid
(Wiley Subscription Services, Inc., A Wiley Company, 1986-05)
The thermally elicited structural and conformational transitions of the polynucleotide analog, poly(-)-2-[2-(thymin-1-yl)propanamido]propenoic acid, P(-)TDHA, have been studied using differential scanning calorimetry (DSC), ...
Demonstration that bovine erythrocyte cytochrome b5 is the hydrophilic segment of liver microsomal cytochrome b5
(Elsevier, 1982-07-26)
A structural comparison has been made between bovine erythrocyte cytochrome b5 and solubilized forms of bovine hepatic microsomal cytochrome b5. Two soluble forms of microsomal cytochrome b5 (designated Forms A and B) were ...
The effect of glycosidases on the survival of rat erythrocytes in circulation
(Elsevier, 1988-07-15)
Enzymic removal of sialyl groups from mammalian erythrocytes resulted in their rapid sequestration from circulation subsequent to autologous transfusion. It has been demonstrated by many investigators that the terminal ...
A method for the chemical synthesis of 14C-labeled fatty acyl coenzyme A's of high specific activity
(Elsevier, 1980-08)
A simple and reliable method, based on that described by W. Seubert (1960, Biochem Prep. 7, 80-83), has been developed for the chemical synthesis of radioactive acyl coenzyme A's. 1-14C-labeled fatty acids (palmitic, oleic, ...
Base-exchange reactions of the phospholipids in cardiac membranes
(Elsevier, 1980-05-28)
Canine cardiac microsomes were shown to incorporate the nitrogenous bases, serine, ethanolamine, and choline, into their respective phospholipids by the energy-independent, Ca2+-stimulated base-exchange reactions. The ...
Fractionation of sialylated oligosaccharides, glycopeptides, and glycoproteins on immobilized elderberry (Sambucus nigra L.) bark lectin
(Elsevier, 1987-04)
A new plant lectin from elderberry (Sambucus nigra L.) bark, which was shown by immunochemical techniques to bind specifically to terminal Neu5Ac([alpha]2-6)Gal/GalNAc residues of glycoconjugates, was immobilized onto ...
Microcalorimetric studies of the heats of solution of bovine myelin basic protein
(Elsevier, 1985-10-04)
Heats of solution for myelin basic protein have been determined using microcalorimetry. All aqueous systems studies yielded negative heats of solution; in contrast, trifluoroethanol produced a small positive heat of solution, ...
Age-related modifications in rat cardiac phosphoglycerate kinase. Rejuvenation of the old enzyme by unfolding-refolding
(Elsevier, 1988-06-29)
The occurrence of age-related modifications in functional and structural properties of several enzymes has been documented; however, the molecular basis of this phenomenon is still mostly unexplained. In the present work ...
