Describing the structure and function of the major biological chemicals in the humans Carbohydrates The main role of carbohydrates is to provide energy to the body. Carbohydrates are broken down into a form of sugar known as glucose. Glucose is carried to every cell in the body by the blood and can be used right away for energy. Glucose is also know as sugar. Carbohydrates imperical formula is Sugars are small molecules which are a product of carbohydrates. As the name implies, a carbohydrate is a molecule whose molecular formula can be expressed in terms of just carbon and water. For example, glucose has the formula C6(H2O)6 and sucrose (table sugar) ...read more.


A glycosidic bond can connect two monosaccharides, such as the linkage of glucose and fructose to create sucrose. It is simply the dehydration reaction between the hydroxide on the right edge of one sugar to the hydroxide on the left edge of the other sugar. A water molecule is extracted (causing a dehydration reaction), and a bond is formed, leaving an oxygen atom between the two monosaccharides, and creating a disaccharide. Structure and function of protein Proteins are made up of amino acids The lines in between the molecules are peptide bonds A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). ...read more.


Lipids Lipids are what is commonly knows as fat The imperical formula for fat is (palmatic acid) glycerol is a important component of all fats and oils. It is basically a sugar type substance that free fatty acids attach to to form something called a trygleceride. A triglyceride consists of three ("tri-") molecules of fatty acid combined with a molecule of the alcohol glycerol ("-glyceride") that serves as the backbone of many types of lipids (fats). a fatty acid is a carboxylic acid (organic acids), often with a long aliphatic tail (long chains), either saturated or unsaturated. Most of the natural fatty acids have an even number of carbon atoms. Structure of water Water consists of only hydrogen and oxygen. Both elements have natural stable and radioactive isotopes. Due to these isotopes, water molecules of masses roughly 18 (H216O) to 22 (D218O) are expected to form. ...read more.

    10cm3 of cyclohexane was added to the ethanol in the beaker and mixed well. 4. The lowest temperature of the mixture was measured using a thermometer. B. To measure the strength of hydrogen bond formed between ethanol molecules The same steps in part A were repeated using same volume of ethanol but 20cm3 and 30cm3 of cyclohexane respectively.

  2. Structure and function of lipids in plants and animals

    Fatty acids in oils are generally: 1. Smaller, 2. Unsaturated. On the other hand, fatty acids in fats are generally: 1. Larger, 2. Saturated. The term "saturated" means that there are no double bonds present between the carbon atoms in the molecule.

  1. Structure and biological significance of lipids.

    it has a low density so it is useful for aquatic life as a buoyancy aid. The adipose tissue is also quite spongy, so it helps to protect vital organs by absorbing shock. Another function of fats is as a water source, as when respiration occurs using fat + oxygen, water is produced as well as energy and carbon dioxide.

  2. Identification of amino acids by chromatography.

    The only mark that did not turn purple once sprayed with ninhydrin, is proline. Proline is individual in that it is bonded to both the nitrogen and the ?-carbon atoms. The resulting cyclic structure influences the protein architecture and means that it turns yellow.

  1. Alkaloids are the most diverse group of secondary metabolites and over 5000 compounds are ...

    formed an oxime (3), which was reduced to an amino derivative (4). On heating to 150-155� with 48% hydrobromic acid this was converted to nornicotine (5), which in turn was methylated to nicotine. The pyridine ring in nicotine is derived from nicotine acid, which itself is derived from aspartic

  2. Investigating the Rate of the Reaction between Bromide and Bromate Ions in Acid Solution

    if concentration is measured in mol dm-3 and volume is measured in cm3. The total volume of the reacting mixture is 40cm3, so the actual concentration of X (in mol dm-3) is given by: (Equation 3.1.2) Putting together equations 3.1.1 and 3.1.2, we get the relationship: (Equation 3.1.3)

  1. Organic Molecule – Lysine.

    This polar amino acid is commonly found on the surfaces of proteins and enzymes, and sometimes appears in the active or binding site. Lysine is an amino acid released in the hydrolysis of many common proteins but present in small amounts or lacking in certain plant proteins; for example gliadin from wheat or zein from corn (maize).

  2. Atomic Structure, Bonding and the Periodic Table. Revision questions.

    But this does not affect the high bond energy between the two species, meaning that as the chemical bonds are so strong separating them requires more energy than is available at room temperature (23oC). b. Aluminium is a solid at room temperature.
