Question

Which of the following is not correct about Linus Pauling?

a) He was awarded the Nobel Prize in Chemistry for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances.
b) He was the first to propose correct models for alpha helix and beta sheet.
c) He provided the first proof of a human disease caused by an abnormal protein - sickle cell hemoglobin.
d) He was the first to determine the crystal structure of hemoglobin.
e) He took 3 grams of vitamin C every day to prevent colds.

Answer 1

The incorrect statement about Linus Pauling is that he was the first to determine the crystal structure of hemoglobin. Correct facts about Pauling include winning the Nobel Prize in Chemistry, proposing models for protein structures, and advocating for high doses of vitamin C.

Step-by-step explanation:

The question asks which statement is not correct about Linus Pauling, an influential chemist and two-time Nobel Prize laureate. The incorrect statement among the options provided is (d) He was the first to determine the crystal structure of hemoglobin. While Linus Pauling made significant contributions to the understanding of hemoglobin, the credit for determining its first crystal structure goes to Max Perutz and John Kendrew.

Correct statements regarding Linus Pauling include:

• (a) He was awarded the Nobel Prize in Chemistry for his research into the nature of the chemical bond.
• (b) He was the first to propose correct models for the alpha helix and beta sheet structures in proteins.
• (c) He provided the first proof of a human disease caused by an abnormal protein - sickle cell hemoglobin.
• (e) He famously took 3 grams of vitamin C every day to prevent colds, despite most clinical research failing to show a connection.

Linus Pauling's work was widely recognized and remains fundamental to modern chemistry, including his studies on electronegativity and molecular resonance.
