What is the difference between sheet and fork lightening?
One is from Neptune
Moves the shortest distance through air alpha beta or gamma?
Is this question from a physics GCSE homework sheet? As I think i have the same sheet! This is the only question i have not found the answer to yet.I think the sheet is P2.11 2a (well, that's what it is called at the top of the sheet).
Which barrier can alpha pass through?
Alpha radiation is stopped easily by thin substances such as a sheet of paper or the skin. It is because of this that alpha radiation is generally non-harmful to humans.
What blocks alpha particles?
A few millimetres of lead.
What is the difference between gamma rays and infrared rays?
An "alpha ray" is not actually a ray at all, as a ray usually means "electromagnetic radiation". The closest yo can get to that is a stream of alpha particles. Alpha particles are helium nuclei (two protons and two neutrons bound together) stripped of their electrons; because they are heavy and relatively slow, they can be stopped typically by a sheet of paper. Infra red rays are electromagnetic radiation, like light or radio, at a frequency which we perceive as "heat".
What levels of protein folding would include shapes identified as helix and pleated sheet?
This is the secondary folding phase where hydrogen bonds between the side chains give you the alpha helix and the beta pleated sheet.
The alpha helix and pleated sheet are examples of?
secondary structure of a protein
Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
What can form a structure such as a helix or a sheet?
A polypeptide chain, which is the primary structure of a protein, can fold into secondary structures such as an alpha-helix or a beta-sheet.
What type of protein shape is characterized by the alpha helix or a flat-pleated sheet?
secondary structure
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.
What type of interaction stabilizes the secondary structure of a protein causing it to form an alpha-helix?
In an α-helix, the polypeptide backbone forms a repeating helical structure that is stabilized by hydrogen bonds between a carbonyl oxygen and an amine hydrogen. These hydrogen bonds occur at regular intervals of one hydrogen bond every fourth amino acid and cause the polypeptide backbone to form a helix.
The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
