    Hexose is a linear six carbon sugar like glucose, fructose, galactose etc. The pyranose ring is formed by the reaction of the hydroxyl group on carbon 5 (C-5) of a sugar with the aldehyde at carbon 1. This forms an intramolecular hemiacetal. If re.

THE PENTOSE PHOSPHATE PATHWAY FORMS NADPH & RIBOSE PHOSPHATE The pentose phosphate pathway (hexose monophosphate shunt, Figure 20–1) is a more complex pathway than glycolysis (see Hexose and pentose metabolism in Rhodotorula glutinis book 17).

Three molecules of glucosephosphate give rise to three molecules Hexose and pentose metabolism in Rhodotorula glutinis book CO 2 and three 5-carbon sugars. Since these three enzymes catalyse physiologically reversible reactions, a non-oxidative pathway for hexose-pentose interconversion exists in amoebae in the absence of transaldolase.

Earlier experiments, in which plants were infiltrated with hexose sugars, such as glucose, fructose, mannose, or galactose, showed that sucrose was.

The pentose phosphate pathway (hexose monophosphate shunt, Figure 20–1) is a more complex pathway than glycolysis (see Chapter 17). Three molecules of glucosephosphate give rise to three molecules of CO 2 and three 5-carbon sugars.

These are rearranged to regenerate two molecules of glucosephosphate and one molecule of the glycolytic.

According to the experimental results, Rhodotorula glutinis had the highest lipid yield in both glucose so le carbon source and mixed sugar in shake flask Size: KB.

D-glucose is a hexose that can be phosphorylated to glucosephosphate by either glucokinase (GlkA) or hexokinase (HxkA) in Aspergillus nidulans.

Glucosephosphate can either enter the pentose phosphate pathway (PPP) or be converted to fructosephosphate by phosphoglucose isomerase (SwoM) [ 4 ] and enter by: 7. Microbodies were observed in cells of Sporobolomyces roseus strain Y and Rhodotorula glutinis strain CY when grown on methane but rarely when grown on glucose.

Analysis of the saturation isotherm revealed the presence of a one-carrier system for L-glucose in the plasma membrane of Rhodotorula glutinis. ing process involved in sugar metabolism, namely non- facultative- or obligate-fermentative (van Dijken and Scheffers ).

The nonfermentative yeasts have exclusively a respiratory metabolism and are not capable of alcoholic fermentation from glucose (e.g.,Rhodotorula glutinis), while the obligate-fermentative yeasts –. A hexose is a monosaccharide with six carbons, but more specifically, an aldohexose is a hexose with an aldehyde functional group at carbon number one.
