- 161: Clinical Chemistry Tests In Medicine
- ... skin, in the abdominal cavity, and in the mammary glands. As stored fuels, triglycerides have an advantage over polysaccharides because they are unhydrated and lack the extra water weight of polysaccharides. Also, because the carbon atoms are more reduced than those of sugars, oxidation of triglycerides yields more than twice as much energy, gram for gram, as that of carbohydrates (Lehninger, 1993). Hyperlipidemia refers to an abnormally high concentration of triglyceride ...
- 162: Carbon
- ... element of carbon, life as we know it would not exist. Carbon provides the framework for all tissues of plants and animals. They are built of elements grouped around chains or rings made of carbon atoms. Carbon also provides common fuels--coal, oil, gasoline, and natural gas. Sugar, starch, and paper are compounds of carbon with hydrogen and oxygen. Proteins such as hair, meat, and silk contain these and other elements ...
- 163: Nies Bohr
- ... after the war was over, he returned to his country, and precipitated the gold from acid and recast the medal. Bohr worked very hard on the peaceful uses of atomic energy and organized the first Atoms for Peace Conference in Geneva in 1955. He was awarded the first Atomic Peace award. He died on November 18, 1962 in Copenhagen, Denmark.

- 165: The Periodic Kingdom: Review
- ... explain relationships between elements to someone who is just learning of the periodic table. In Chapter 3 a deeper look is taken into the inner workings of the elements. Atkins now relates characteristics of the atoms themselves to there placement of the map. By looking at the map one is able to find out characteristics of an atom. For example as you move down a group atomic mass increase and atomic ...
- 166: Fossil Fuel Consumption, CO2 and Its Impact on Global Climate
- ... a basic product of all fossil fuel consumption. Although the chemical reaction in combustion of fossil fuels is not always simple, it can be summarised as the release of the carbon combined with atmospheric oxygen atoms to form carbon dioxide. This process is often referred as respiration, such that: C6H12O6 + 6O2 + heat ฎ 6CO2 + 6H2O Here, we see that carbon dioxide is not an impurity, as a matter of fact, life on ...
- 167: Changes in the Earth's Environment
- ... disturbing changes to the environment, that of the discovery of the hole in the ozone layer and the theory of global warming (McKibben,1987). Ozone is a molecule of oxygen, made up of three oxygen atoms and it's existence is essential for many life supporting systems. Ozone occurs at two levels in the atmosphere; the stratosphere and the troposphere. In the stratosphere it is concentrated into the ozone layer', and ...
- 168: Socrates
- ... world. Some believed that it was made out of numbers, others thought that it was made of a single substance, or many different substances, while still conflicting philosophers theorized that everything was formed out of atoms, and even illusions. Socrates had his own, different ideas. He believed that the world was made of forms that are not within the reach of our senses, but only of our thoughts. This means, for ...
- 169: Nucleic Acids
- ... and thymine (T). In RNA the purine bases are the same as in DNA, but the pyrimidines are cytosine and uracil (U). These rings have the chemical property of being bases because of the nitrogen atoms they contain. Adenine always forms 2 hydrogen bonds with thymine. Cytosine always forms 3 hydrogen bonds with guanine. Phosphate Group The phosphate group gives nucleotides, and the nucleic acids that they make up, their acidic ...
- 170: Nuclear Weapons
- Nuclear Weapons Research and Writing 12-2 A Nuclear weapon is any weapon that gets its destructive power from the transformation of matter in atoms into energy. They include missiles, bombs, artillery shells, mines and torpedoes. Another name for nuclear weapons are Atomic bombs or Hydrogen bombs. The United States was the first country to ever use a Nuclear weapon ...
