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…...

...Carbohydrates, Proteins, lipids and Nucleic Acids Tiffany Osbey Jackson State University Lab Report Authors: Tiffany Osbey Portia Mcmlertrey Jamia Ransome Darrius Bryant Abstract: Organic molecules are those primarily made up of carbon, hydrogen and oxygen. The common organic compounds of living organisms are carbohydrates, proteins, lipids, and nucleic acids. Each of these macromolecules (polymers) are made of smaller subunits (monomers). The bonds between these subunits are formed by dehydration synthesis. This process requires energy; a molecule of water is removed (dehydration) and a covalent bond is formed between the subunits (Fig.1). Breaking this bond is called hydrolysis; it requires the addition of a water molecule and releases energy. Each class of these macromolecules has different structures and properties. For example, lipids (composed of fatty acids) have many C-H bonds and relatively little oxygen, while proteins (composed of amino acids) have amino groups (-NH3+) and carboxyl (-COOH) groups. These characteristic subunits and chemical groups impart different properties to the macromolecules. For example, monosaccharide’s such as glucose are polar and soluble in water, whereas lipids are non-polar and insoluble in water. Objective: Perform lest to detect the presence of biology important carbohydrates, proteins lipids and nucleic acid. Explain the importance of a positive and a negative control in biochemical test.

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......

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......

To investigate the present of protein in food samples with Biuret solution. 4. To determine the present of lipid in food samples using brown paper. Introduction : We had learned about that all living organisms are made up of molecules, each molecule serve its own special purpose. Molecule can be divided into two types, macromolecules and micro molecules. The molecules that we are studying in this experiment are macromolecules. In this case, we are studying on 3 types of macromolecules, carbohydrates, protein and lipid that present in different food. Carbohydrate can be divided into monosaccharide, disaccharide and polysaccharide. Monosaccharide is the simplest sugar that appears in food, the most common example of this is glucose. Disaccharide is a double sugar, which means by it linked two monosaccharides together to form a disaccharide. The examples for disaccharide are maltose, galactose and sucrose. The example of polysaccharide is starch. Protein is build up by the monomers, amino acid. Each protein has it own special sequence that is different from others. The Biuret reagent is used to determine the presence of protein as it turns the original blue colour of the solution to purple when it react with the protein, specifically between the bonds of amino acid. Lipids......
