xylulose การใช้

• D-Ribulose is the diastereomer of D-xylulose.
• This enzyme catalyze the direct formation of D-xylulose from D-xylose.
• Thiamine pyrophosphate cofactor in yellow and xylulose 5-phosphate substrate in black . ()
• It is associated with a deficiency of L-xylulose reductase, necessary for xylitol metabolism.
• The isomerization of xylose to xylulose has its own commercial applications as interest in biofuels has increased.
• Therefore, xylulose 5-phosphate is reversibly converted into ribulose 5-phosphate by this epimerase.
• This is a mechanism by which phosphopentose epimerase converts ribulose 5-phosphate to xylulose 5-phosphate.
• L-xylulose reductase, contained in red blood cells, is composed of both a major and minor isozyme.
• The use of glucose isomerase very efficiently converts xylose to xylulose, which can then be acted upon by fermenting yeast.
• It is C3 of D-ribulose 5-phosphate which undergoes this epimerization, forming D-xylulose 5-phosphate.
• "' Xylulose "'is a ketopentose, a monosaccharide containing five carbon atoms, and including a ketone functional group.
• As the enzyme converts ribulose 5-phosphate into xylulose 5-phosphate, the latter is further metabolized into erythrose 4-phosphate.
• The insufficiency of L-xylulose reductase activity causes an inborn error of metabolism disease characterized by excessive urinary excretion of L-xylulose.
• The insufficiency of L-xylulose reductase activity causes an inborn error of metabolism disease characterized by excessive urinary excretion of L-xylulose.
• For example, a side activity of Rubisco yields small amounts of xylulose-1, 5-bisphosphate, which can inhibit Rubisco activity.
• L-Xylulose is a reducing sugar, so it may give false diagnosis of diabetes, as it is found in high concentrations in urine.
• In coupled sequence, fructokinase and aldolase produce glycolaldehyde, a precursor to oxalate, from D-xylulose via D-xylulose 1-phosphate.

• The CbbY enzyme dephosphorylates xylulose-1, 5-bisphosphate to the natural metabolite xylulose-5-phosphate, thereby preventing inhibition of Rubisco.
