![]() are compounds as they are made up of different elements with different atoms. On the other hand, Calcium carbonate (CaCO3), NaCl, H2O, etc. are the molecules, as they have two or more atoms. Let’s take an example to understand in a better way, like Hydrogen gas (H2), Oxygen (O2), water (H2O), HCl, Ozone (O3), etc. Starch can be broken down to glucose (Simple Sugar molecules by heating with Sulphuric Acid (Hydrolysis) – H 2O molecule is added.Ĭhromatography can be used to identify small molecules of sugar Fats:įats are formed through condensation reaction of fatty acids (Carboxylic Acids) and Glycerol (3 Carboon atom chains having OH attached with every Carbon atom).So, we can say that any combination of atoms is a molecule, but when the combination of atoms is from different elements, it is known as the compound. Hydrolysic of Carbohydrates to convert them to simple sugar: ![]() Glucose polymerise each other to form starch ![]() Simplest Carbohydrate C 6H 12O 6 (Glucose) starch.Ĭarbohydrates contain Carbon, Hydrogen and Oxygen. The chromatogram needs to be sprayed with a locating agent (Ninhydrin) so that they can become visible and be compared to other pure samples of the monomer.Ĭarbohydrates are polymers made up of small sugar molecules joined together e.g. The products of the hydrolysis of protein (amino acids) and Carbohydrates can be separated and identifies through chromatography. Is a reaction in which molecules are broken down by reaction with water, in the presence of Alkali or Acid. This adds water molecules into the polymer. Proteins can also by hydrated back into amino acids, by heating them with Sulphuric Acid (H 3PO 4). Proteins are possessing the same amide linkages as Nylon but with different monomer units. They are joined together by condensation polymerization.Įach amino acid has an acidic functional group and an amino functional group. Protein have similar linkage to that of Nylon (amide linkage) –Thus can be called Polyamide. When two amino acids combine with each other, protein is formed and H 2O is a by-product. Natural Polymers are formed by condensation polymerization. Thus may lead to flodding in low lying areas. Plastics that require Chloro-Flouro Carbons (CFC) during production may contribute to global warming when the CFC is allowed to escape.Plastics are Carbon based polymers – burn easily. ![]()
