Which of the following is the least likely to be involved in stabilising the three-dimensional folding of most proteins? [2016]
Hydrogen bonds
Electrostatic interaction
Hydrophobic interaction
Ester bonds
(4)
Tertiary structure or three dimensional structure of protein is stabilised by several types of bonds-hydrogen bonds, ionic bonds, van der Waal's interactions, covalent bonds and hydrophobic bonds.
Given below are two statements:
Statement I: A protein is imagined as a line, the left end represented by first amino acid (C-terminal) and the right end represented by last amino acid (N-terminal)
Statement II: Adult human haemoglobin consists of 4 subunits (two subunits of type and two subunits of type.)
In the light of the above statements, choose the correct answer from the options given below: [2023]
Statement I is true but Statement II is false.
Statement I is false but Statement II is true.
Both Statement I and Statement II are true.
Both Statement I and Statement II are false.
(2)
A protein is imagined as a line, the left end represents first amino acid (N-terminal amino acid) and right end represents the last amino acid (C-terminal amino acid).
