Who discovered biotin?

Answer 1

Biotin, also known as vitamin B7 or vitamin H, is a crucial nutrient that plays a vital role in energy metabolism and maintaining healthy hair, skin, and nails. The discovery of biotin is credited to several scientists, but the primary recognition goes to Paul György, a Hungarian-American scientist.

In the late 1930s, Paul György discovered that biotin was essential in preventing certain skin conditions and hair loss in animals. Shortly after, scientists identified that biotin was a water-soluble vitamin that belonged to the B-vitamin complex. Kögl and Tönnis, two researchers, later succeeded in isolating biotin in its pure form from egg yolk in 1935.

Since its discovery, biotin has been extensively studied for its importance in various metabolic processes, including the synthesis of fatty acids and the breakdown of carbohydrates.

Answer 2

W. G. Bateman discovered biotin in 1916. That adding raw eggwhite to an otherwise adequate diet produced toxicity and disease. Called egg-white injury, the symptoms includedeffects on the skin (scaly dermatitis and hair loss), thenervous system (depression, lassitude, and muscle pain),the gastrointestinal tract (anorexia and nausea), and even the cardiovascular system (abnormal heart action, i.e.,changes in the electrocardiogram). Later research identified the culprit to be avidin, a protein in egg white which avidly binds biotin, preventing its absorption. Thus, the biological necessity of biotin became evident, and by 1935scientists had isolated it in pure form. Biotin, originally calledvitamin H after the German word Haut meaning "skin", belongs to the water soluble B vitamin class.
