Hemoglobin is an iron-containing protein found in the blood of nearly all vertebrates and many invertebrates. It transports oxygen from the lungs or gills of an animal to the tissues. Four polypeptide chains, each wrapped in a specific way around its own heme group, make up the hemoglobin molecule.
Correction Appended. Alger Hiss, the erudite diplomat and Harvard-trained government lawyer who was convicted of perjury in an espionage case that became one of the great riddles of the Cold War, died yesterday at Lenox Hill Hospital in New York City. He was 92 and lived in Manhattan.
In 1949, the first trial resulted in a hung jury, but in 1950, Hiss was convicted. On January 21, 1950, he was sentenced to five years in prison, ending an important case that helped further confirm the increasing penetration of the U.S. government by the Soviets during the Cold War.
