| biography:
| Biochemist, born in Greenville, South Carolina, USA. He studied at Yale, and spent his career at Illinois University. From the 1930s he studied mammalian nutrition. In one series of experiments he replaced all protein by amino acids, and so found that not all 20 of them are essential for a given species; in the rat, 10 are essential (including threonine, which he discovered in 1936). In the adult human diet, only eight are essential, as he showed by experiments using student volunteers. |
