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 the present of carbohydrates in foods

Anissa Davis 32130161 The Industrial Process of Sulphuric Acid6 The contact process: At the heart of this process is a reversible reaction in which sulphur dioxide is converted to sulphur trioxide‚ but first you have to produce sulphur dioxide. Stage 1: Making sulphur dioxide Either burn sulphur in air: S (s) + O₂ →SO₂(g) Or heat sulphide ores strongly in air: 4F eS₂(s) + 11O2(g)→2F e₂O₃(s) + 8SO₂(g) Stage 2: Making sulphur trioxide Now the sulphur dioxide is converted into sulphur trioxide using an excess of air

ABSTRACT The effect of inorganic cofactor such as Magnesium to the rate of respiration of yeast was determined using Durham tube assembly with the substrate glucose. After thirty minutes‚ the test tube with the cofactor in the form of Magnesium sulphate MgSO4 showed the higher amount of carbon dioxide evolved which was measurable through volume and was one of the by- products of cellular respiration. This stated that the higher amount of CO2 evolved‚ the higher the rate of respiration. Thus‚ the

ketone or aldehyde functional groups). The groups reduce CuSO4‚ a component of Benedicts‚ resulting in a color change in the benedicts solution from a turquoise to a brick to rusty-brown color. Another class of carbohydrates called starches‚ a polysaccharide‚ can be detected using the Iodine’s test. Having a high molecular weight‚ iodine attaches to the helical structure of starches yielding a blue-black precipitate. The Biuret’s test identifies proteins by oxidizing 4-6 peptide bonds of a protein

Introduction to Biochemistry Biochemistry : a multidisciplinary science that explores the chemistry of living organisms and molecular basis for changes occurring in living cells. Principal areas of Biochemistry 1. Struture and Function of Biomolecules Based on structure depend the function (structure function relationship) Example: Hemoglobin S differs from regular adult hemoglobin (hemoglobin A) by just one single amino acid. A valine replaces a glutamine in the 6th position of the beta

1. The Structures of the Human Heart The human heart has four chambers: two ventricles‚ each of which is a muscular chamber that squeezes blood out of the heart and into the blood vessels‚ and two atria‚ each of which is a muscular chamber that drains and then squeezes blood into the ventricles. The two atria reside at the top of the heart; the two ventricles are at the bottom. And‚ the heart is divided into left and right halves‚ so there is a left atrium and left ventricle‚ as well as a right atrium

Oparin and Haldane’s Theory: The chemical evolution of life is the most widely accepted theory of origin of life. It is based on the fact that primitive earth was different from the earth which is present today. It was proposed by Russian bio-chemist‚ A.I Oparin (1923) and was supported by Englishman J.B.S Haldane (1928). This theory can be well-explained under the following headings: i. Biogeny ii. Chemogeny iii. Cognogeny 1. Formation of the earth: i. When the earth was formed‚ it was extremely
