(Pgs. 37-41) organisms are living things with components that biotechnologists work directly with they are the raw materials of biotechnology cells are the smallest unit of life that makes up all living organisms‚ these can be manipulated in many ways Escherichia Coli (E.Coli) is a bacterium that is commonly used by biotechnology companies for the development of products multicellular composed of more than one cell

made up from Carbon‚ Hydrogen and Oxygen It is the main source of energy of cells. It can be divided into 3 groups – Monosaccharides‚ Disaccharides and polysaccharides. Monosacharides : They are known as simple sugars They cannot be hydrolysed/broken down into smaller units Eg. Glucose‚ Fructose‚ Galactose They are reducing sugars Disaccharides : They are formed by condensation reaction. Also known as complex sugars They are water soluble‚ sweet tasting and can be crystallized

• Organic chemistry- special study of chemistry dealing with molecules containing carbon and hydrogen • Hydrocarbon- an organic molecule consisting only of carbon and hydrogen. • Functional groups- a specific configuration of atoms commonly attached to the carbon skeletons of organic molecules and involved in chemical reactions. • Hydroxyl group: a chemical group consisting of an oxygen atom joined to a hydrogen atom. Molecules possessing this group are soluble in water and are called alcohols

Lesson 02.08 DBA/Module Exam Lesson 02.01: Chemistry of Life · Explain why biological macromolecules are important for everyday life. Cells make large macromolecules by bonding smaller molecules together into chains called polymers (from the Greek polys‚ "many‚" and meris‚ "part"). Polymers are large molecules composed of many identical or similar subunits called monomers. There are four categories of biological macromolecules that provide energy and structure to living organisms and their cells

Our aim: was to find out which substances from our five samples have reducing sugars present to determine what they may be for example; they could be monosacchrides or disaccharides. This was carried out by using Benedict’s test. To find out which substances from our five samples were non-reducing sugars‚ since some disaccharides are reducing sugars and this would be carried out by using Benedict’s test. To find out which substances had starch present using iodine To find out which substances

purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays an important role in structural of living organisms. There are various of test can be done to identified
