Which of the following vitamins was not discovered by Dr. Casimir Funk?
Answer:
Dr. Casimir Funk is known for his important contributions to the field of vitamins and nutrition. However, there is one vitamin that was not discovered by Dr. Casimir Funk, and that is vitamin K.
Dr. Casimir Funk is credited with discovering and coining the term “vitamin” itself. He conducted extensive research on vitamins, especially vitamin B, and played a key role in identifying its significance in preventing diseases like beriberi and pellagra.
However, vitamin K was actually discovered by a Danish scientist named Henrik Dam in the 1920s. Dam’s research focused on blood clotting and he observed that chickens fed a fat-free diet experienced bleeding issues. He identified a compound he called “coagulation vitamin” which was later renamed to vitamin K.
It is important to note that while Dr. Casimir Funk did not discover vitamin K, his work and research on vitamins as a whole made significant contributions to our understanding of their role in maintaining health and preventing diseases.
