Protein secondary structure - Wikipedia
Secondary Structure • The primary sequence or main chain of the protein must organize itself to form a compact structure This is done in an elegant fashion by forming secondary structure elements • The two most common secondary structure elements are alpha helices and beta sheets formed by repeating amino acids with the same (??) angles |

What does protein secondary structure mean?
- Protein secondary structure is the three dimensional form of local segments of proteins.The two most common secondary structural elements are alpha helices and beta sheets, though beta turns and omega loops occur as well. Secondary structure elements typically spontaneously form as an intermediate before the protein folds into its three dimensional tertiary structure.
What does the secondary structure of a protein result from?
- The secondary structure of a protein is due to the folding of the polypeptide chain into different folds due to hydrogen bonding and Vander Waal forces. Whereas the tertiary structure of proteins is defined as the arrangement of secondary structure content in 3-dimensional space. While some proteins consist of more than one polypeptide, their ...
What happens at the secondary structure of protein?
- What happens in the secondary structure of a protein? Hydrogen bonding between amino groups and carboxyl groups in neighboring regions of the protein chain sometimes causes certain patterns of folding to occur. Known as alpha helices and beta sheets, these stable folding patterns make up the secondary structure of a protein.
