00:01 Hi students in a given question we have to identify which of the following answer choices is incorrect with respect to the protein structure so in order to solve this question let's see different types of the levels of the protein structures and the bonds associated with them so primary structure of the protein is the linear sequence of amino acids which helps us to know the positional information like which amino acid is present in which position the details we will able to get with respect from the primary structure and as one amino acid is linked with another amino acid through the peptide bond so type of linkage is present in the primary structure is peptide bond and it is provide the sequential information of amino acids so the proteins are not always present just like a linear sequences rather than they will tend to get different forms those are called as the secondary structures those are called as beta a pleated sheets that is one form where they are like you know pages of the book and the next one is a beta pittlet sheets and the next one is alpha ellices so these are the most common secondary structures and these are formed due to the intra you know intra hydrogen bond in the bio hydrogen bond that is taking place within the polypebaly peptide chains.

01:30 So, secondary structure is by hydrogen bonds.

01:32 Now the tertiary structure, tertiary structure of proteins are nothing but three dimensional structure and for the most of the protein, this is biologically active form.

01:43 So proteins are active in tertiary structures and these bonds, these tertiary structure is stabilized by the different bonds.

01:53 They includes disulfide bonds, then hydrophobic interoperic.

01:59 Interactions, hydrogen bonds.

02:03 So these are the different types of interactions and they are also stabilized by the ionic bonds.

02:09 So disulfide bonds are the characteristic features of the tertiary structure of the proteins...
