What else can I help you with?
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 structure refers to the twisting spiral shape formed by the sequence and properties of amino acids?
The phrasing is a little odd, but I suspect the term you're looking for is "alpha helix". Other "twisting spiral shapes" are possible, for example the 3.10 helix and the pi helix, but the alpha helix is the most common and most familiar.
How do you find out the length of alpha helix and beta helix?
This is quite simple. Using stoichiometry to keep track of units, simply take the number of amino acids in the particular alpha helix and multiply by 15 angstroms. This is the length the alpha helix is advanced along the length axis by each additional A.A. For a beta helix it become more difficult however and you must know how many sheets you are taking into account.
how many amino acids are there in one turn of alpha helix?
3.6 amino acid.
The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta pleated sheet represent the secondary structure of proteins. Both structures are formed by the interaction of amino acids within the polypeptide chain through hydrogen bonding.

What are the differences between a right-handed alpha helix and a left-handed alpha helix in protein structures?
The main difference between a right-handed alpha helix and a left-handed alpha helix in protein structures is the direction in which the helix twists. In a right-handed alpha helix, the helix twists in a clockwise direction, while in a left-handed alpha helix, the helix twists in a counterclockwise direction. This difference in twisting direction affects the overall shape and stability of the protein structure.
What type of helix forms RNA?
Alpha helix
How does collagen helix differs from alpha helix?
A collagen helix is less compact (because it goes into triple helices), and it is a left-handed helix. An alpha helix is more compact and hence requires more rotation of bonds to form (hence proline is not very common...has an imidazole ring). It is a right-handed helix, and goes into double helices instead.
What did Herman branson invent?
The alpha helix
Which direction does the alpha helix twist predominantly in proteins: right-handed or left-handed?
In proteins, the alpha helix predominantly twists in a right-handed direction.
Why is Branson famous?
He is famous because of his research of Alpha Helix protein structure. It is spiral chain of amino acids stabilized by hydrogen bonds.http://www.answers.com/topic/alpha-helix
Single helix is more stable as compared to the double helix?
The double helix of DNA is more stable than a single helix due to the hydrogen bonding between complementary base pairs and the structural support provided by the sugar-phosphate backbone. The double helix structure allows for efficient storage and replication of genetic information.

What is the axial length of alpha helix containing 78 amino acids?
the pitch of a alpha helix is o.54 nm , that is the distance between two points at the same horizontal position in a helix if is held up right. there are 3.6 aa per turn. therefore if there are 78 aa then Lengthhelix= (78 /3.6)* 0.54 nm
Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
