Did you know that Edward Adelbert Doisy was born today in 1893? He was a biochemist. In 1943 he won the Nobel Prize in Physiology or Medicine for identifying the structure and chemical characteristics of Vitamin K. The body needs vitamin K to bind calcium in bone and other tissue. Low levels of vitamin K weakens bones. Vitamin K is also used to coagulate blood. Coagulation is the process where blood thickens from a liquid to a gel; this is very important after an injury to prevent blood loss. Vitamin K is found in leafy green vegetables such as spinach, broccoli, and cabbage.

Edward Adelbert Doisy shared the 1943 Nobel Prize with Henrik Dam.
Edward Adelbert Doisy completed his PhD in 1920 at Harvard. He worked in the Department of Biochemistry at Washington University in St. Louis. St. Louis University renamed their Department of Biochemistry after EA Doisy, in his honor.
In the 1930s he studied estrone. Adolf Butenandt studied the molecule concurrently. In 1939, only Butenandt was awarded the Nobel Prize.
Coagulopathy is a bleeding disorder that results from Vitamin K deficiency. Other symptoms include anemia, easy bruising, nosebleeds, and bleeding gums.
In plants, vitamin K has a role in photosynthesis.
