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.
Alpha helices are right-handed due to the specific arrangement of the peptide backbone and the hydrogen bonding pattern that stabilizes their structure. In a right-handed helix, the amino acid side chains project outward, which allows for optimal interactions and minimizes steric clashes. This configuration is energetically favorable, making right-handed helices more common in proteins. Additionally, the chirality of the amino acids contributes to the overall handedness of the helix.
You should supply more information.
Actually the best place to get more information on "Sigma Alpha Epsilon" would be the related English Wikipedia page. The article is entitled accordingly "Sigma Alpha Epsilon".
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.
Proteins can adopt various structural forms, including alpha helices, beta pleated sheets, and globular shapes, which are determined by their amino acid sequences and interactions. Alpha helices are coiled structures stabilized by hydrogen bonds, while beta pleated sheets consist of adjacent strands linked through hydrogen bonds, creating a sheet-like formation. Globular proteins, on the other hand, are more compact and spherical, often functioning as enzymes or hormones. These diverse shapes are crucial for the protein's specific functions in biological processes.
Hemoglobin - formed with alpha helices and/or beta sheets, but as one, contiguous polypeptide. Superoxide dismutase would be a good example of a quaternary structure protein, since it is made of more than one polypeptide chain.
