Every protein is described as primary, secondary, tertiary structures.
00:11
The alpha carbon that bonds with the amine and carboxyl group have some rotation which allows the arrangement of amino acids, which in short is given as aa, in different angles but in limited values.
00:31
These angles are called as the torsion angles that helps in the folding of polypeptide chains into different secondary structures such as alpha helix, beta sheets, beta pleated sheets and more.
01:00
It is stabilized by the forces that is present between the amino acids located at some distance from each other.
01:12
The ionic interactions or the salt linkages between the charged groups on the side chains helps only to maintain a particular folded area of the protein and it cannot stabilize the whole protein as such.
01:35
Hence, option a is not a correct answer.
01:41
Similar to option a, the hydrogen bonds that is formed between the peptideal.
01:47
Bonds don't stabilize the secondary structure of protein.
01:51
Hence option b is not the correct answer...
