What is the function of erythrose?
Erythrose 4-phosphate is an intermediate in the pentose phosphate pathway and the Calvin cycle. Oxidative bacteria can be made to use erythrose as its sole energy source.
Why is erythrose a monosaccharide?
Erythrose belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. Erythrose exists in all living organisms, ranging from bacteria to humans.
Is erythrose a carbohydrate?
The natural isomer is D-erythrose. It is a member of the class of compounds known as pentoses. Pentoses are monosaccharides in which the carbohydrate moiety contains five carbon atoms. Erythrose is very soluble (in water)….3D Structure for HMDB0002649 (Erythrose)

What is erythrose and threose?
What we see is that when two common substitutes, in this case the H and OH groups, of the stereogenic centers are on the same side, we have the sugar erythrose and when they are on opposite sides, it is the threose. Threose and erythrose exist in two enantiomeric forms which are designated as D and L enantiomers.
Is erythrose a pentose sugar?
The pentose sugars ribose and deoxyribose are part of the nucleotides that make up the crucial nucleic acids like DNA and RNA. So the correct option is ‘Erythrose’.
Is erythrose polar?
D-erythrose is the D-enantiomer of erythrose. It has a role as a plant metabolite. It is an enantiomer of a L-erythrose….3.1Computed Properties.

What is erythrose form?
Erythrose is a tetrose saccharide with the chemical formula C4H8O4. It has one aldehyde group, and is thus part of the aldose family. The natural isomer is D-erythrose; it is a diastereomer of D-threose.
Why Ketoses are reducing sugars?
All monosaccharide ketoses are reducing sugars, because they can tautomerize into aldoses via an enediol intermediate, and the resulting aldehyde group can be oxidised, for example in the Tollens’ test or Benedict’s test.
Is threose chiral or achiral?
chiral
D-threose is chiral and it does have an enantiomer. Its enantiomer is called L-threose.
What is erythro compound?
Erythro and threo are two configurations in which molecules are written when the molecules have a chiral carbon atom. Erythro is the configuration when the same groups are on the same side of the carbon atom and Threo is the configuration when the same groups are on the opposite side of the carbon atom.
Is erythrose optically active?
Reduction of Monosaccharides Draw the Fischer projections of the alditols of d-erythrose and d-threose. One compound is optically active, and the other is a meso compound.
What is the medical definition of erythrose?
Medical Definition of erythrose : a syrupy aldose sugar C4H8O4 that is the epimer of threose Learn More About erythrose Dictionary Entries Near erythrose
What is the isomer of erythrose?
Erythrose is a tetrose saccharide with the chemical formula C 4 H 8 O 4. It has one aldehyde group, and is thus part of the aldose family. The natural isomer is D -erythrose; it is a diastereomer of D -threose.
What is the L-enantiomer of erythrose?
L-erythrose is the L-enantiomer of erythrose. It is an enantiomer of a D-erythrose. The data from CAS Common Chemistry is provided under a CC-BY-NC 4.0 license, unless otherwise stated.
What is the formula for erythrose in standard state?
Erythrose. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Erythrose is a tetrose saccharide with the chemical formula C 4 H 8 O 4. It has one aldehyde group, and so is part of the aldose family. The natural isomer is D -erythrose.
