The Methyl Ethers of Hexuronic Acids

open access: yes, 1954
Publisher Summary This chapter provides an overview of the methyl ethers of hexuronic acids. Hexuronic acid residues occur in a large number of different polysaccharides. The chapter focuses on the methyl ethers of the naturally occurring D-glucuronic, D-galacturonic, and D-mannuronic acids, and their derivatives.

Early Markers of Cardiac and Skeletal Muscle Metabolic Derangement in the Apc(min/+) Male Mouse. [PDF]

open access: yesCancer Rep (Hoboken)
ABSTRACT Background and Aims Cancer cachexia is a metabolic and wasting disease that occurs in up to 80% of cancer patients. Currently, there are no clear diagnostic criteria, its effects are irreversible, and it cannot be treated. Most patients progress undetected to late stages of cancer cachexia, stop responding to traditional treatment, and die ...

Glycosaminoglycans as Polyelectrolytes: Charge, Interactions, and Applications. [PDF]

open access: yesChembiochem
Glycosaminoglycans (GAGs) are linear, anionic biopolymers with their functions tightly linked to their charge. This review approaches GAGs from a polyelectrolyte perspective, shedding light on how the distribution of sulfate groups and, thus, negative charges, governs their interactions with other biomolecules.

Enzymes Suitable for Biorefinery to Coproduce Hexaric Acids and Electricity from Hexuronic Acids Derived from Biomass

open access: yes, 2017
The present invention relates to a method and microbial host strain for converting a hexuronic acid to a hexaric acid. In particular, the invention relates to the con-version of D-galacturonic acid to meso-galactaric acid (mucic acid). The invention also concerns an isolated nucleotide sequence.

Protein O-glycosylation in the Bacteroidota phylum. [PDF]

open access: yesFEBS Open Bio
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

Sphingolipids in bean leaves (Phaseolus vulgaris)

open access: yesJournal of Lipid Research, 1969
Phytoglycolipid has been isolated for the first time from plant leaves (Phaseolus vulgaris). The purified product (almost identical with the phytoglycolipid isolated from flax seed) was a ceramide attached through phosphate diester linkage to an ...
