Stereoselective protecting group free synthesis of d,l-gulose ethyl glycoside via multicomponent enyne cross metathesis—hetero Diels–Alder reaction [PDF]

open access: yes, 2009
An efficient and stereoselective synthesis of d,l-gulose was described. The key step of the synthetic route is represented by a multicomponent enyne cross metathesis—hetero Diels–Alder reaction which allows the formation of the pyran ring from cheap and ...

Hexose transport in human myoblasts [PDF]

open access: yesBiochemical Journal, 1989
The present investigation reports on the hexose transport properties of human myoblasts isolated from normal subjects and from patients with Duchenne muscular dystrophy (DMD). Similar to rat myoblast L6, normal human myoblasts possess a high- (HAHT) and a low- (LAHT) affinity hexose transport system.

Hexoses Biorefinery: Driving Glucose Dehydration over Sulfonic Polymer and Hybrid Acid Catalysts

open access: yesReactions
Glucose is the most abundant monosaccharide as it is the primary unit of cellulose and starch, which are the more relevant feedstocks for biorefineries.

Validation of a Rapid GC-MS Procedure for Quantitative Distinction between 3-O-Methyl- and 4-O-Methyl-Hexoses and Its Application to a Complex Carbohydrate Sample

open access: yesSeparations, 2020
Methylation of one hydroxyl group of monosaccharides occurs in some bacteria, fungi, worms, molluscs, and also in plants. Although knowledge on the exact functions of this process is missing, methylation is an option to modulate glycan structures thereby

Continuous synthesis of 5‐hydroxymethylfurfural from biomass in on‐farm biorefinery

open access: yesGCB Bioenergy, 2022
5‐hydroxymethylfurfural (HMF) is the object of extensive research in recent times. The challenge in the industrial production of HMF is the choice of cheap, hexose feedstock. This study compares continuous HMF synthesis from hexoses—fructose and glucose,
