Synthetic Diamonds: Better a diamond with flaws than a pebble without.

Diamonds are essentially made out of carbon atoms. They are solids that can go through the process of high temperature and high pressure. (Pilgrim, 2011) It is known to man that diamonds are the hardest material on the earth. (Sean, 2008) With a melting point of 3550 ℃and a boiling point of 4827 C. As you can see above that diamonds have an extremely high melting point (m.p) and a high boiling point (b.p.) The pressure to produce diamonds are also in extreme conditions, diamonds are produced with a temperature range of 900 and 1300 degrees Celsius. Then put under pressure of 725,000 pounds per square inch. (World of Carbon, n.d.) Diamonds have these properties because they are macromolecules; (Encyclopedia of Britannica n.d.) macromolecules are atoms that join together and from on big molecule. In which they also have a strong bonds. Each Carbon atom has a valence electron of four, diamonds are made out of units of carbon atoms joined together using the strongest linkage in chemistry’s perspective, covalent bonding. The carbon is bonded with tetrahedral shape, it has a structural unit consisting of eight atoms, which is arranged in a cube. The tetrahedral shape is very strong and stable, which leads to why diamonds have such a high melting point. (Anne Marie, n.d.) They are also unable to conduct electricity this is because there is no free electrons since the valence electron is tightly bonded together.

Diamonds are one of the most expensive mine stones on earth, in the diamond market it is known that present days, people increasingly is wanting more of these mine stones, and this resource is soon to be lost. Therefore in 1954 Howard Tracy Hall invented the synthetic diamonds. This diamond is technologically processed, opposed from the natural geological process. (Wikipedia...

Macromolecules and Their Parts

...There are four macromolecules that make up all living things. These macromolecules are proteins, carbohydrates, lipids, and nucleic acids. All of these macromolecules are formed from functional groups. The functional group hydroxyl is found in every macromolecule. All of these macromolecules except for lipids are hydrophilic. All of these macromolecules are broken down into monomers by hydrolysis reactions. Proteins have methyl groups, amino groups, and carboxyl groups. Proteins are polymers of amino acids. Proteins functions are determined by how they are folded. Proteins with a primary structure have no function. Proteins with a secondary structure are in the shape of an alpha helix but still have no function. Once a protein achieves tertiary structure that protein has a function. Quaternary structures in proteins are made of many motifs and have the most advanced functions of all the structures, many of them being enzymes due to their three dimensional structure. However, a protein can become unfolded, and once it does it cannot be reversed, this is called denaturation and makes the protein loose its functions. All proteins and polypeptides are links of amino acids held together by peptide bonds. Peptide bonds are formed between two molecules when the carboxyl group and the amino groups in two atoms react which causes dehydration synthesis. Carbohydrates have carbonyl groups, and are organic compounds every time due to the presence of a carbon atom and also have......

Macromolecules: Identification

...INTRODUCTION Carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus are a very important part of all living organisms. These elements combine is various ways to make the molecules that make up biological systems. There are four major molecules (macromolecule) found in living organisms – Carbohydrates, Lipid, Proteins and Nucleic Acids. They all have different chemical properties and can be identified by their functional groups. A chemical test that is sensitive to these functional groups can be used to identify or test for the presence of each of the macromolecules. This lab tests for major macromolecules using such tests. (Karp, 2005) The Iodine test is used to detect starch and glycogen, the Benedict’s test is used to test for reducing sugars and the Biuret test is used to detect protein. (Landesberg, 2011) The Iodine test is useful to distinguish starch and glycogen from other polysaccharides. A polysaccharide is a carbohydrate whose molecules consist of sugar molecules. Plants and animals store their simple sugars in the form of polysaccharides. The polysaccharide that plants use is called starch, and it has a lot of glucose units connected together with glycosidic bonds. Starch also has a polymer called amylose, which reacts with the iodine during the test and gives it a blue-black colour. Glycogen, in animals, is bigger (in terms of molecular weight) and it’s structurally very different. It has a lot of branches and they give glycogen the reddish-brown colour......

Biological Macromolecules

...homeostasis (to maintain a life supporting environment), you must understand the related biological concepts. We will start with the organic compounds, which all include carbon; without carbon you can not survive. Organic compounds also contains other elements such as hydrogen, oxygen, phosphorus, nitrogen, or sulfur. The foods you eat provide the organic compounds that your cells are made up of and that they use to function. Organic compounds give the elements carbon, hydrogen, oxygen (“CHO”) that are needed to make biological macromolecules. Biological macromolecules, are large molecules (also known as polymers). A monomer is a molecule that is able to bond in long chains. Monomers are small molecules that may be joined together in a repeating fashion to form more complex molecules called polymers. Usually, polymers are organic (but not necessarily). Hydrogen bonds are responsible for the properties of water and many biological molecules. Macromolecules, that are necessary for life, include carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates...

The Relationship Between Water And Macromolecules

...Although I took biology class back in high school, I never truly paid attention or really understood the material. Taking this course helped me learn more about the scientific method, atoms the chemical bonds, the importance of water, and the macromolecules. An observation is always the first step to the scientific method. Collecting data helps understand the full detail of the experiment. A hypothesis would then need to be formed. It’s the question to be studied through experiments. Experiments would need to be tested to find out your hypothesis. The results would be your overall conclusion as to whether the hypothesis is true or not. According to Mader and Windelspecht, “The atomic theory states the elements consist of tiny particles called atoms” (22). Each atom has an atomic weight. Protons have a positive charge. Neutons have a neutron charge. Electrons...

Protein Maromolecules

...Introduction: The study of Macromolecules in the body is significantly examined through Anatomy and physiology understanding the body at its most primary, fundamental level. Roles carried out by macromolecules are crucial to life contributing to functions throughout the entire body and by understanding these structures and methods, effective medicines to treat conditions can be developed successfully whilst the rest of the body can be grasped. In particular, I have decided to research Protein macromolecules. Proteins are unique in the way of their structures and found contributing to virtually all cells of the body. The following essay explains the distinctive structures of Protein, variant forms and proteins role toward almost all biological processes. Body: Structure of Protein The structure of a Protein Macromolecule consists of more than one hundred amino acids covalently bonded. A covalent bond is the result of shared electrons amongst atoms and in protein macromolecules; these bonds connect Amino acids to another ultimately creating a Polypeptide chain. A polypeptide chain includes three or more Amino acids linked together by this chemical bond. Amino acids ultimately determine the shape and three dimensional configurations of Protein, are organic compounds and have a two carbon bond comprising of one carboxyl group and one amino group. A carboxyl group (COOH) consists of a carbon atom, two oxygen atoms, Hydrogen atom and joins to an Amine group (NH2) Each amino......

...similarities to study individual macromolecular components found within all living cells. Through this experiment we will learn the basic sub-units that make up each of these macromolecules while also learning some of their important structural characteristics. This experiment will consist of two parts. The first of which will divide the yeast cells into three of its major macromolecular components: nucleic acids, proteins and polysaccharides. These components are large macromolecules that are quite unique in their composition, structure and function. However, they share a common feature as each macromolecule is composed of repeating subunits, characteristic of the macromolecule. The subunits are linked together by a bond between two adjacent subunits, formed by the loss of water (condensation). Thus, macromolecules can be broken down by the addition of water across the bond, in a process known as hydrolysis. This process was used in the experimental procedure to allow analysis of each individual macromolecule in its subunit form. Proteins are hydrolyzed into amino acids, nucleic acids are hydrolyzed into sugar, base and phosphate, and polysaccharides are broken down into simple sugars. In the second part of the experiment, the principle method of chromatography was used to analyze the macromolecules isolated in part one of the experiment. With this technique, individual molecular species were separated from one another. This separation technique was performed for the......

Lactose that is not broken down in the small intestine passes into the large intestine, where bacteria feed on it and belch out gaseous by-products, producing uncomfortable symptoms. 2. Explain why lactose intolerance has evolved differently in humans spread throughout the world. The enzyme lactase, like all proteins, is encoded by a DNA gene. Lactose-intolerant people have a defect in their lactase gene. A small change in a DNA nucleotide sequence can have a major effect on the production of a protein and the well-being of an organism. 3.
