Xylulose is a potentially valuable rare sugar used as starting material for antiviral and anticancer drug development in pharmaceutical industries.
Abstract. d -Xylulokinase (XK; EC 2.7.1.17) catalyzes the ATP-dependent phosphorylation of d -xylulose (Xu) to produce xylulose 5-phosphate (Xu5P). In mammals, XK is the last enzyme in the glucuronate-xylulose pathway, active in the liver and kidneys, and is linked through its product Xu5P to the pentose-phosphate pathway.
1 Φεβ 2020 · Conversion of lignocellulose to biofuels and chemicals requires three main steps: destroying the lignocellulose structure by pretreatment, hydrolyzing hemicellulose/cellulose to fermentable monomeric sugars by enzymatic saccharification, and finally converting monomeric sugars to chemicals or biofuels by microbial fermentation.
1 Ιαν 2016 · This review describes the occurrence of L-xylulose in certain metabolic pathways, its bioproduction, and application potential. Chemical structure of L-xylulose. Fungal L-arabinose...
Xylulose is phosphorylated at the C5–OH position by xylulokinase (XK) to yield xylulose-5-phosphate (X5P), which is further channeled into glycolytic intermediates such as glyceraldehyde-3-phosphate (GA3P) and fructose-6-phosphate (F6P) via the pentose phosphate pathway (PPP).
• Describe the main points of cell wall ultrastructure: chemistry, morphology, and hierarchy • Distinguish molecular vs. supramolecular structure with cellulose • Recognize the crystalline polymorphs of cellulose
Thomas Heinze. Abstract Cellulose, a fascinating biopolymer and the most common organic compound on earth, is comprehensively reviewed. Details of its crystalline phases are given, starting with a description of molecular and supramolecular structures, including the hydrogen bond systems.
