Hubert Bradford Vickery
Hubert Bradford Vickery (28 February 1893 – 27 September 1978) was a Canadian-American plant biochemist who conducted early experiments to determine the amino acid compositions of proteins. While serving as editor of the '' Journal of Biological Chemistry'' he standardized the use of the D (dextro) and L (laevo) prefixes to indicate optical isomerism in amino acids which was later incorporated into the IUPAC standard. Biography Vickery was born in Yarmouth, Nova Scotia, the second son of Mary Katherine Dudman and Edgar Jenkins Vickery. His father, a bookshop owner, gifted him the book '' Fourteen weeks in chemistry'' by J. Dorman Steele for Christmas at the age of twelve which initiated a lifelong interest in chemistry. He then went to Dalhousie University and graduated with honours in chemistry and then taught at a high school in Halifax. This ended in December 1917 when a nearby ship exploded and damaged the school. Vickery then worked at the Imperial Oil Company as an an ...

Amino Acid
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code. Amino acids can be classified according to the locations of the core structural functional groups, as Alpha and beta carbon, alpha- , beta- , gamma- or delta- amino acids; other categories relate to Chemical polarity, polarity, ionization, and side chain group type (aliphatic, Open-chain compound, acyclic, aromatic, containing hydroxyl or sulfur, etc.). In the form of proteins, amino acid '' residues'' form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliadin
Gliadin (a type of prolamin) is a class of proteins present in wheat and several other cereals within the grass genus ''Triticum''. Gliadins, which are a component of gluten, are essential for giving bread the ability to rise properly during baking. Gliadins and glutenins are the two main components of the gluten fraction of the wheat seed. This gluten is found in products such as wheat flour. Gluten is split about evenly between the gliadins and glutenins, although there are variations found in different sources. Both gliadins and glutenins are not water-soluble, but gliadins are soluble in 70% aqueous ethanol. There are three main types of gliadin (α, γ, and ω), to which the body is intolerant in coeliac (or celiac) disease. Diagnosis of this disease has recently been improving. Gliadin can cross the intestinal epithelium. Breast milk of healthy human mothers who eat gluten-containing foods presents high levels of non-degraded gliadin. Types The α, γ, and ω gliadin t ...

People From Yarmouth, Nova Scotia
A person (plural, : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal obligation, legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its us ...

Yale University Faculty
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Testing At Bikini Atoll
Nuclear testing at Bikini Atoll consisted of the detonation of 23 nuclear weapons by the United States between 1946 and 1958 on Bikini Atoll in the Marshall Islands. Tests occurred at 7 test sites on the reef itself, on the sea, in the air, and underwater. The test weapons produced a combined fission yield of 42.2 Mt of TNT in explosive power. The United States and its allies were engaged in a Cold War nuclear arms race with the Soviet Union to build more advanced bombs from 1947 until 1991. The first series of tests over Bikini Atoll in July 1946 was codenamed Operation Crossroads. ''Able'' was dropped from an aircraft and detonated above the target fleet. The second, ''Baker'', was suspended under a barge. It produced a large Wilson cloud and contaminated all of the target ships. Chemist Glenn T. Seaborg, the longest-serving chairman of the Atomic Energy Commission, called the second test "the world's first nuclear disaster." The second series of tests in 1954 was code ...

Edwin Joseph Cohn (December 17, 1892 – October 1, 1953) was a protein scientist. A graduate of Phillips Academy, Andover 911 and the University of Chicago 914, PhD 1917 he made important advances in the physical chemistry of proteins, and was responsible for the blood fractionation project that saved thousands of lives in World War II. Liver juice fractionation and concentration for treatment of pernicious anemia In 1928, as group leader at Harvard Medical School, Cohn was able to concentrate, by a factor of 50 to 100 times, the vital factor in raw liver juice which had been shown by Minot and Murphy to be the only known specific treatment for pernicious anemia. Cohn's contribution allowed practical treatment of this previously incurable and fatal illness, for the next 20 years. Blood fractionation project Cohn became famous for his work on blood fractionation during World War II. In particular, he worked out the techniques for isolating the serum albumin fraction of bloo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Burr Osborne (chemist)
Thomas Burr Osborne (August 5, 1859 – January 29, 1929) was a biochemist who, with Lafayette Mendel, independently discovered Vitamin A, though Elmer McCollum and Marguerite Davis were ultimately given credit, as they had submitted their paper first by three weeks. He is known for his work isolating and characterizing seed proteins, and for determining protein nutritional requirements. His career was spent at the Connecticut Agricultural Experiment Station. Biography Thomas Burr Osborne was born in New Haven, Connecticut on August 5, 1859. He was the son of lawyer Arthur Dimon Osborne and the grandson of US Representative Thomas Burr Osborne. He earned an undergraduate degree from Yale College in 1881, and a PhD in chemistry there in 1885. He married Elizabeth Annah Johnson on June 23, 1886, and they had one son.
