Some parts of a protein can have a helical structure - one of the most common secondary structures in proteins is the alpha helix.
However, helix - especially double helix - will probably be more often used in the description of DNA, so be careful not to mistake the two.
No it is probably secondary structure. a-Helix is one of the structure formed by long amino acid chain.
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
Protein is very high in calsium. It will easily change to level 87
Primary structure.
Quaternary
Is the sequence of amino acids that form the protein
the primary structure is the lowest level
The primary structure
Primary, tertiary and quaternary levels of protein structure.
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
hydrogen bonds
Protein is very high in calsium. It will easily change to level 87
The quaternary level.
Protein often exhibit fourth level or quaternary structure. The dimer, is the simplest form of fourth level structures is called a dimer, which is seen in DNA binding protein.
Primary structure.
The coiling of the protein chain background into an alpha helix is the secondary structure. This is caused by the H-bonded arrangement of the backbone of th protein.
