Beta D-glucopyranose is more stable than alpha D-glucopyranose because of the spatial orientation of the hydroxyl group at the first carbon atom. In beta glucopyranose, the hydroxyl group is trans to the bulky CH2OH group, leading to less steric hindrance compared to alpha glucopyranose where the hydroxyl group is cis to the CH2OH group. This difference in spatial orientation results in beta D-glucopyranose being more energetically favorable and hence more stable.

What do unstable isotopes become when they decay?
Unstable isotopes become more stable isotopes or different elements when they decay through processes such as alpha or beta decay. The decay results in the emission of radiation in the form of alpha or beta particles and gamma rays.
Which form predominates either alpha or beta D glucose in blood?
In the bloodstream, the beta form of D-glucose predominates over the alpha form. This is because the beta form is more stable and less likely to convert to the alpha form due to the presence of enzymes that help maintain this equilibrium.
What radiation does a nucleus with more than 82 protons usually emit?
A nucleus with more than 82 protons is usually unstable and may emit alpha or beta radiation to become more stable. This process helps lower the number of protons and neutrons in the nucleus, bringing it closer to a more stable configuration.
How do the mass and size of an alpha particle compare with mass and size of beta particle?
An alpha particle is larger and has more mass than a beta particle. An alpha particle is made up of two protons and two neutrons, giving it a mass of 4 atomic mass units, whereas a beta particle is much lighter and has a mass close to that of an electron. Size-wise, an alpha particle is larger in diameter compared to a beta particle.
Why beta glucose is more stable than alpha?
Beta glucose is more stable than alpha glucose due to the axial orientation of the hydroxyl group on the anomeric carbon in beta glucose, which reduces steric hindrance within the molecule. This conformation results in a more stable intramolecular hydrogen bonding pattern compared to alpha glucose, making beta glucose less prone to mutarotation.
Which is more stable alpha or beta glucose?
beta glucose
What is the difference structure and configuration of glucose?
Glucose has a six-carbon backbone with a carbonyl group and five hydroxyl groups. In terms of configuration, glucose can exist in two forms: alpha-D-glucose and beta-D-glucose, which differ in the orientation of the hydroxyl group on the first carbon atom.
Which is more stable alpha-fructose of beta-fructose?
Beta-fructose is more stable than alpha-fructose. This is because in beta-fructose, the OH group on carbon-1 is in the equatorial position, resulting in lower steric hindrance compared to alpha-fructose where the OH group is in the axial position. This makes beta-fructose less prone to mutarotation and degradation reactions.
What do unstable isotopes become when they decay?
Unstable isotopes become more stable isotopes or different elements when they decay through processes such as alpha or beta decay. The decay results in the emission of radiation in the form of alpha or beta particles and gamma rays.
A radioactive isotope is an isotope that?
undergoes spontaneous decay, emitting radiation in the form of alpha particles, beta particles, gamma rays, or positrons in order to achieve a more stable state.
What happens when the ratio of neutrons to protons is not a stable ratio?
If it is not stable, then the atom will likely either emit alpha radiation or beta radiation in order to become more stable.
Which form predominates either alpha or beta D glucose in blood?
In the bloodstream, the beta form of D-glucose predominates over the alpha form. This is because the beta form is more stable and less likely to convert to the alpha form due to the presence of enzymes that help maintain this equilibrium.
What level of protein structure is associated the alpha helix and beta pleated sheet?
It depends on the primary sequence of amino acids as to which secondary structure is more stable. Both structures use hydrogen bonds to stabilize the structures, however in an alpha helix, these hydrogen bonds are with the peptide and in beta sheets the hydrogen bonds are between beta peptide strands. I really don't know which structure is more stable... -alpha helix seems to be a more common structure -and B sheets lose some H bonding during hair pin turns and during twists. -But an alpha helix has a dipole whereas an antiparalle beta sheet doesnt. -weighing it up i would assume an alpha helix to be more stable but that would be a guess from me.
Would an atom of radioactive gold be more likely to decay by alpha emission or beta emission?
Gold never decays by alpha emission, it either decays by -beta, +beta, K capture, or gamma emission depending on isotope.Natural gold is isotopically pure gold-197, which is stable.
What radiation does a nucleus with more than 82 protons usually emit?
A nucleus with more than 82 protons is usually unstable and may emit alpha or beta radiation to become more stable. This process helps lower the number of protons and neutrons in the nucleus, bringing it closer to a more stable configuration.
Which is better mine craft alpha or beta?
Minecraft Beta is better than Minecraft Alpha. If you want more Beta and more Alpha versions. Donate to mojang, so I can tell the creators to create, create more versions.
Spontaneous disintegration of a radionuclide accompanied by the emission of alpha or beta particles or gamma rays?
This process describes radioactive decay, where an unstable radionuclide spontaneously transforms into a more stable form by emitting particles (alpha or beta) or photons (gamma rays). This emission reduces the nucleus' energy and brings it closer to a stable state.
