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.


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.


Alpha helices and beta-pleated sheets are examples of .?

protein secondary structures, which are common motifs found in protein folding. Alpha helices are formed by a right-handed coil of amino acids stabilized by hydrogen bonding, while beta-pleated sheets are formed by hydrogen bonding between adjacent strands of amino acids running in parallel or antiparallel orientation.


Where can one find more information about alpha helices?

One can find information about alpha helices in your local library.You could find about all other helices in that category and how they are used in life.


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 structure does hemoglobin have?

Alpha helices


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).


Name three typical shapes of protein molecules?

Globular: 3D structure with a rounded shape, often involved in enzymatic functions. Fibrous: Long and thin structure, providing support and structure to cells and tissues. Membrane-bound: Embedded in cell membranes, involved in transport and cell signaling.


What type of secondary structure does hemoglobin have?

Hemoglobin is a protein with a combination of secondary structures, predominantly consisting of alpha helices and beta sheets. These structural elements help maintain the shape and function of hemoglobin as a globular protein.


What does a protein's alpha helices and beta sheets fold together to create?

Alpha helices and beta sheets fold together to create the secondary structure of a protein, forming the protein's overall 3D shape. This structure helps determine the protein's function by influencing how it interacts with other molecules in the body.
