Question

When a protein is denatured he protein breaks down into its atoms The hydrogen bonds of the secondary structure are altered The primary structure is disrupted The protein can never go back to its original form Which of the following is true of all lipids? They are all derived from cholesterol They are soluble in water or oil They all are stored as a source of energy They are hydrophobic In the news one hears that high cholesterol is bad. What are good features cholesterol? Steroids need cholesterol for their synthesis Cholesterol promotes the synthesis of proteins Cholesterol is a part of the cytoskeleton Cholesterol accumulates in the walls of small arteries and keeps

The correct answer for the question is " The hydrogen bonds of the secondary structure are broken"

STRUCTURE OF PROTEIN

PRIMARY STRUCTURE: In this the atoms are bound with chemical bonds . These bonds are peptide bonds . Denatureation does not alter any peptide bonds . Hence primary structure is intact in primary structure.

SECONDARY STRUCTURE : The primary structure undergoes multiple folds among itself to form the secondary structure . These folds are bound together by hydrogen bonds, salt bridges and disulphide bonds

TERITIARY STRUCTURE : Complex folding of the secondary structure results in the formation of the teritiary structure of the protein. The bonds are same as in secondary structure.

During the process of denaturation the secondary and teritiary structures are altered because of the hydrogen bonds, salt bridges adn disulphide bonds are broken .

Denaturation is an IRREVESIBLE PROCESS in which all the basic structures which give teh shape to the protein are broken ( secondary & teritirary structures). Hence the protein will never return to its original form .

Agents causing denaturation are
