¶ … properties of a Carbon atom that make it ideally suited to produce varied carbon skeletons?
Besides water, carbon molecules are the most significant contributors to life. The structural and functional diversity of organic molecules emerges from the ability of carbon to form large, complex and diverse molecules by bonding to itself and to other elements such as hydrogen, oxygen, nitrogen and sulfur. Carbon atoms are the most versatile building blocks of molecules. Each one has an atomic number of 6; therefore, it has 4 valence electrons. This means that these electron completes its outer energy shell by sharing valence electrons in four covalent bonds and are not likely to form ionic bonds. Covalent bonds link carbon atoms together in long chains that form the skeletal framework for organic molecules.
Discuss what would happen if no water was present during degradation of a bio-molecule.
Since bio-molecules are complex they are made up of simpler components that have their own unique characteristics. Water is also a good solvent due to its polarity. The solvent properties of water are vital in biology, because many biochemical reactions take place only...
In general, ionic and polar substances such as acids, alcohols, and salts are easily soluble in water, and nonpolar substances such as fats and oils are not. Non-polar molecules stay together in water because it is energetically more favorable for the water molecules to hydrogen bond to each other than to engage in van der Waals interactions with nonpolar molecules.
-Discuss the four possible levels of protein structure and relate each level to particular bonding patterns.
There are four levels of protein structure: primary, secondary, tertiary, and quaternary. These levels also reflect their temporal sequence. Proteins are synthesized as a primary sequence and then fold into secondary then tertiary and then quaternary structures. The linear sequence of amino acids constitutes a protein's primary structure. Secondary structures arise from non-covalent interactions between amino acids across the chain. Tertiary structure is subdivided into certain portions that are termed motifs and domains. Two or more polypeptide chains may bind to each other to form a quaternary structure.

The concepts of energy and matter are slightly more intuitively understood, but before reading the passage a class discussion that attempts to define tese terms would also be useful. After reading the passage once, the question of what substances are elements could be put to the class. No doubt some substances such as water will be listed that are basic compounds, and not true elements. These answers can then be
This information is utilized to create new products and substances that are used on a regular basis. For example, chemists could use the COSY process to understand how to create a new kind of raincoat that will be even more water resistant. To determine this, the protons inside the molecules of the raincoat would have to be examined through the COSY process. This will identify the peaks inside the
Chemical Properties of the Universe Astronomers hypothesize that about 5 million years ago, the Solar System was filled with a plethora of hot gases and dust, swirling around a hot core. They think that once the core approached about 1 million degrees, the physics and chemical properties caused the gases to coalesce, forming the sun. During this time, there were millions and millions of asteroids. As these asteroids collided with one
Uranium Trioxide (UO3) Uranium trioxide occurs as an orange powder and is the form of uranium identified in the colored glass found evidencing its use as a paint color component dating back to the First Century AD (Krauss, 2001).

From a materials development perspective, this is the important part: "The significance of this advance is this: if a material as expensive and rare as a diamond can be turned into a 'commodity,' then the applications of a variety of other materials, including everything from copper and ceramics to steel, can also be improved and utilized in different ways" (Uldrich, 2006, p. 17). From a pragmatic perspective, these developments
Physical Science Elemental Isotopes and Allotropes The 19th century discovery of the periodic table of the elements by Dmitri Mendeleev gave an organizing principle to understanding the structure of the atom, and deriving atomic weight. On the periodic table, the lighter elements have atomic weights which correspond to whole numbers. Hydrogen has an atomic weight of 1, which corresponds to the idea that it has only one proton (and the weight of
