Structure of a water-insoluble -glucan isolated from a streptococcal organism
(Elsevier, 1983-08-16)
The structure of the extracellular polysaccharide (water-insoluble -glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, ...
Isolation and characterization of a glycopeptide from human senescent erythrocytes
(Elsevier, 1983-08-16)
A glycopeptide (called "senescence-factor glycopeptide", SF-G) has been isolated from a tryptic digest of human erythrocytes by specific adsorption and elution from immobilized peanut lectin. SF-G was detectable in old but ...
A further investigation of the stannic chloride-catalyzed condensation reaction of 1-hexene and 1,2,3,5-tetra-O-acyl-[beta]--ribofuranoses
(Elsevier, 1983-04-16)
The reaction of 1-hexene with either 1-O-acetyl-2,3,5-tri-O-benzoyl-[beta]--ribofuranose (5b) or 1,2,3,5-tetra-O-acetyl-[beta]--ribofuranose (5a) in the presence of stannic chloride leads to the formation of a complex ...
