Sam Granick (February 16, 1909 – April 29, 1977) was an American biochemist known for his studies of ferritin and iron metabolism more broadly, of chloroplast structure, and of the biosynthesis of heme and related molecules.
(1933) and Ph.D. (1938) degrees from the University of Michigan, where he completed a dissertation in plant physiology.
[1] Between 1942 and 1946, Granick and Michaelis, along with Alexandre Rothen, published a series of important research papers on ferritin and other ferric compounds in the Journal of Biological Chemistry.
In the first paper,[2] Granick showed that contrary to earlier studies purified ferritin contains no nucleic acid and varies in its content of iron and phosphorus.
A second paper, by Granick and Michaelis,[3] showed that iron could be removed from ferritin to produce apoferritin.
