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 else can I help you with?
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.
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.
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
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 secondary structure. This repetitive structure is stabilized by hydrogen bonds between the backbone amide hydrogen and carbonyl oxygen atoms.
Collagen and keratin are example of?
Keratin and Collagen are examples of proteins.
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
Which of these proteins in mammals show only primary and secondary structures?
Collagen and keratin are examples of proteins in mammals that primarily exhibit only primary and secondary structures. Collagen is known for its triple helix structure, while keratin is a fibrous protein that forms alpha-helices and beta-sheets.
What is the molecular weight of the alpha 1 chain in type V collagen?
The alpha 1 chain in type V collagen has a molecular weight of approximately 140 kDa.
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.
Polymerization of amino acids to form procollagen filaments occurs?
during the process of collagen synthesis. This involves the formation of a triple helix structure comprising three polypeptide chains, known as alpha chains, that are derived from procollagen molecules. This stabilization of the procollagen structure is crucial for the subsequent formation of collagen fibers.
