no they are not. they are stereoisomers(configurational)
Structural isomers.
isomers that differ in the arrangement literally. so the difference between the cylic glucose molecule that is a ring and the non ring glucose. these two are structural isomers. if molecule A and B have the same molecular formula but look different and are thus arranged differently they are structural isomers.
conformational isomers.
these are isomers that differ from each other simply by the rotation around a single bond. if molecule B can be twisted around the single bonds to get molecule A then A and B are conformational isomers.
configurational isomers (stereoisomers).
if molecules A and B do not fall into the above two categories, then they are stereoisomers. these type of isomers differ in the spatial arrangement of atoms. so if molecule A was the mirror image of molecule B then these two molecules would be a type of stereoisomers called (Enantiomers).
for alpha glucose the OH group attached to the anomeric carbon is not the same as teh CH2OH group on the other side of the hemiacetal( on the other side of the ether oxygen.). ie. if the OH is axial down then the CH2OH is equatorial up. and vice versa.
the molecule is beta glucose when these two substituents are the same in this aspect. both either equatorial or axial.
the difference between axial and equatorial is spatial adn in the arrangement of atoms connected to the carbon ring and solely a difference in this aspect (alpha or beta) means the molecules are stereoisomers.

What is the percentage of alpha and beta in an equimolar mixture of alpha d glucose and beta d glucose?
64% of Beta and 36% of alpha.
What polysaccharides consists of alpha and beta D glucose units?
the polysaccharides that consists of alpha D- glucose units is starch the polysaccharides that consists of beta D- glucose units is cellulose
Which form predominates either alpha or beta D glucose in blood?
the beta predominate
Why beta glucose is more stable than alpha?
They form different disaccharides due to there molecular structures. Alpha forms Maltose with a 1-4 glycosidic bond between each alpha glucose and another, and Beta forms the disaccharide Cellobiose with a 1-4 glycosidic bond between each beta glucose and another.
What is basic difference between the structures of Cellulose and Starch?
Both, cellulose and starch, has a linear structure of glucose monomers connected by glyosidic bonds (1-4 glycosidic bond = Carbon atom number 1 linked with Carbon atom number 4 of the next glucose monomer's). The basic structural difference is whether the linkage is alpha or beta glycosidic bond. (Alpha and beta denotes the spatial aspect of the bondage. Alpha bondage is below the plane, beta bondage is above the plane). Cellulose is linked by beta-1-4 glycosidic bonds. Starch is linked by alpha-1-4 glycosidic bonds.
What are two isomers of glucose?
Glucose C6H12O6 has six isomers, there are two configurations of Glucose, D-Glucose and L-Glucose, both of these have further three isomers one open chain and two closed chain or cyclic isomers one is Alpha-Glucose and other is Beta-Glucose.
What is the percentage of alpha and beta in an equimolar mixture of alpha d glucose and beta d glucose?
64% of Beta and 36% of alpha.
Which is more stable alpha or beta glucose?
beta glucose
Is starch a polymer of beta glucose?
starch is an alpha-glucose, Cellulose is a beta-glucose molecule
What polysaccharides consists of alpha and beta D glucose units?
the polysaccharides that consists of alpha D- glucose units is starch the polysaccharides that consists of beta D- glucose units is cellulose
What are the monosaccharides and disaccharides in amylose and cellulose?
beta D glucose and alpha D glucose respectively
What are the three common simple sugars in your diet?
The three most common monosaccharides in one's diet are most likely glucose (both the alpha and beta isomers), galactose, and fructose. These sugars make up three common diasaccharides: Maltose, Lactose and Sucrose Maltose (malt sugar) is made from 2 alpha glucoses (linked via an alpha glycosidic bond) Lactose (milk sugar) is made from galactose and beta glucose (linked via a beta glycosidic bond) Sucrose (table sugar) is made from alpha glucose and fructose (linked via an alpha glycosidic bond.)
Why shape formed when beta glucose molecules join in a single chain is different from that formed when alpha glucose molecules join in a single chain?
Because beta is mo beta than alpha, you feel me?
Why the shape formed when beta glucose molecules join in a single chain is different from that formed when alpha glucose molecules join in a single chain?

What two monosaccharides join to make cellobiose?
Alpha glucose and beta glucose with a beta 1 4 glycosidic linkage!
Which form predominates either alpha or beta D glucose in blood?
the beta predominate
What compounds would be classified as carbohydrates?
There are quite a few compounds that are also a carbohydrate. Some of those are beta-glucose, alpha-glucose, beta-deoxyribose, beta-ribose, alpha-galactose and beta-fructose.
