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.

Collagen and keratin are example of?
Keratin and Collagen are examples of proteins.
The coiling of the protein chain backbone into an alpha helix is referred to as?
The coiling of the protein chain backbone into an alpha helix is referred to as the secondary structure. It is composed of several polypeptide chains.
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 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
When DNA is coiled and folded and twisted into short condensed strands?
When DNA is twisted it is called a double helix and when DNA is coiled folded and twisted into short consended strands it is called alpha halix
What fiber is strong and composed of dense fibrous proteins?
connective tissue in animals is composed of many different proteins including collagen. Collagen is a protein that is composed of 3 left handed alpha helices interwoven with one another, which gives it great strength. Collagen is a rare example of a left handed alpha helix, and is thought to occur as such due to the post translational hydroxylation of the proline residues (proline typically does not occur in alpha helices because it distorts the helix).
What type of helix forms RNA?
Alpha helix
What did Herman branson invent?
The alpha helix
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
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.
Collagen and keratin are example of?
Keratin and Collagen are examples of proteins.
Hemoglobin is an example of a protein with what type of structure?
Alpha Helix.
Why must glycine be found at regular intervals in the collagen triple helix?
A small or (in the case of glycine) no side chain is necessary to allow for the coiling ofbthe collagen.

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.
Structure of keratin?
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
