Gary Keith Ackers (1939 - 2011) was Emeritus Professor of Biochemistry and Molecular Biophysics of Washington University School of Medicine. His research focused on thermodynamic linkage analysis of biological macromolecules, addressing the molecular mechanism of cooperative O2 binding to human hemoglobin since the early 1970s. He was a Fellow of the Biophysical Society The Biophysical Society is an international scientific society whose purpose is to lead the development and dissemination of knowledge in biophysics.

Washington University School Of Medicine
Washington University School of Medicine (WashU Medicine) is the medical school of Washington University in St. Louis, located in the Central West End neighborhood of St. Louis, Missouri. Founded in 1891, the School of Medicine shares a campus with Barnes-Jewish Hospital, St. Louis Children's Hospital, and the Alvin J. Siteman Cancer Center. The clinical service is provided by Washington University Physicians, a comprehensive medical and surgical practice providing treatment in more than 75 medical specialties. Washington University Physicians are the medical staff of the school's two teaching hospitals – Barnes-Jewish Hospital and St. Louis Children's Hospital. They also provide inpatient and outpatient care at the St. Louis Veteran's Administration Hospital, hospitals of the BJC HealthCare system, and 35 other office locations throughout the greater St. Louis region. History Medical classes were first held at Washington University in 1891 after the St. Louis Medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macromolecule
A macromolecule is a "molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass." Polymers are physical examples of macromolecules. Common macromolecules are biopolymers (nucleic acids, proteins, and carbohydrates). and polyolefins (polyethylene) and polyamides (nylon). Synthetic macromolecules Many macromolecules are synthetic polymers (plastics, synthetic fibers, and synthetic rubber. Polyethylene is produced on a particularly large scale such that ethylene is the primary product in the chemical industry. Macromolecules in nature * Proteins are polymers of amino acids joined by peptide bonds. * DNA and RNA are polymers of nucleotides joined by phosphodiester bonds. These nucleotides consist of a phosphate group, a sugar ( ribose in the case of RNA, deoxyribose in the case of DNA), and a nucleotide base (either adenine, guan ...

Hemoglobin
Hemoglobin (haemoglobin, Hb or Hgb) is a protein containing iron that facilitates the transportation of oxygen in red blood cells. Almost all vertebrates contain hemoglobin, with the sole exception of the fish family Channichthyidae. Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the other tissues of the body, where it releases the oxygen to enable aerobic respiration which powers an animal's metabolism. A healthy human has 12to 20grams of hemoglobin in every 100mL of blood. Hemoglobin is a metalloprotein, a chromoprotein, and a globulin. In mammals, hemoglobin makes up about 96% of a red blood cell's dry matter, dry weight (excluding water), and around 35% of the total weight (including water). Hemoglobin has an oxygen-binding capacity of 1.34mL of O2 per gram, which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood plasma alone. The mammalian hemoglobin molecule can bind and transport up to four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biophysical Society
The Biophysical Society is an international scientific society whose purpose is to lead the development and dissemination of knowledge in biophysics. Founded in 1958, the Society currently consists of over 7,000 members in academia, government, and industry. Although the Society is based in the United States, it is an international organization. Overseas members currently comprise over one third of the total. Origins The Biophysical Society was founded in response to the growth of the field of biophysics after World War Two, as well as concerns that the American Physiological Society had become too large to serve the community of biophysicists. Discussions between prominent biophysicists in 1955 and 1956 led to the planning of the society's first meeting in Columbus, Ohio in 1957, with about 500 attendees. Among the scientists involved in the early effort were Ernest C. Pollard, Samuel Talbot, Otto Schmitt, Kenneth Stewart Cole, W. A. Selle, Max Lauffer, Ralph Stacy, Herm ...

PNAS
''Proceedings of the National Academy of Sciences of the United States of America'' (often abbreviated ''PNAS'' or ''PNAS USA'') is a peer-reviewed multidisciplinary scientific journal. It is the official journal of the National Academy of Sciences, published since 1915, and publishes original research, scientific reviews, commentaries, and letters. According to '' Journal Citation Reports'', the journal has a 2022 impact factor of 9.4. ''PNAS'' is the second most cited scientific journal, with more than 1.9 million cumulative citations from 2008 to 2018. In the past, ''PNAS'' has been described variously as "prestigious", "sedate", "renowned" and "high impact". ''PNAS'' is a delayed open-access journal, with an embargo period of six months that can be bypassed for an author fee ( hybrid open access). Since September 2017, open access articles are published under a Creative Commons license. Since January 2019, ''PNAS'' has been online-only, although print issues are avail ...

Scientists From Missouri
A scientist is a person who Scientific method, researches to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different er ...
