Answer is: <span>functional groups.
</span>Functional groups<span> are specific </span>groups<span> that are responsible for the characteristic chemical properties of molecule.</span>
<span>Proteins have nitrogen and oxygen in functional group.
Nucleic acids and some lipids have phosphorus in fuctional group.
Carbohydrates have oxygen in functional group for example.</span>
It does<span>, however, change the </span>mass<span> of the nucleus. </span>Adding<span> or removing </span>neutrons<span>from the nucleus are how isotopes are created. Protons carry a positive electrical charge and they alone determine the charge of the nucleus.</span>
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
Answer : The length of protein will be, 36.8 A⁰
Explanation :
First we have to calculate the amino acid residue.
Given:
Length of single strand of protein = 27.0 kDa
Mean residue mass = 110 Da
Now we have to calculate the number of turns in protein.
As there are 3.6 amino acid per turn of the alpha-helix.
Now we have to calculate the length of the protein.
As, we know that the length of each turn = 0.54 A⁰
Thus, the length of protein will be, 36.8 A⁰
