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

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

Chapter 1: • Name four properties that all life forms have. Order, Regulation, Growth and Development, and Energy Processing 2. Briefly discuss Darwin’s theory of Natural Selection. The process of descent with modification is Darwin’s take on evolution. The mechanism he proposed for this was called natural selection, which is another way of saying unequalled reproductive success. First, he observed overproduction and competition. Next, he observed individual variation. Finally Darwin concluded

The reason why humans first look for water when they travel to other new planets due to the fact that in order for living organisms to survive in those planets, there needs to be sources of water to sustain life on those planets. If humans can find water on a different planet, then they could make the claim that life could already be on these planets, or that life can be sustained on these planets. My evidence is that in order for life to be sustained on a planet, this planet must contain the six

The isolation and purification of genomic DNA requires three main processes which include, lysing of cells to release the DNA, purifying the solution by removing unwanted macromolecules, and precipitating the DNA from the solution. The process of isolation and purification requires several reagents. The Nuclei Lysis Solution contains lysozyme and EDTA. The lysozyme is an enzyme that degrades peptidoglycan, which is a rigid exoskeleton cell wall that protect the bacteria (3). Disrupting the peptidoglycan

right amount of food and drink to achieve and maintain a healthy body weight. A balanced diet consists of vitamins, carbohydrates, minerals, vitamins, fats (lipids) and fibre which is also known as roughage. CARBOHYDRATES Carbohydrates are macromolecules which and contains carbon, hydrogen and oxygen (C,H,O). There are also two types of sugars, sweet soluble and starches which are non-soluble. Sugars can also be single or simple sugars.Carbohydrates can be found in a wide variety of foods such

detection of starch presence, Benedict’s test for determination of reducing sugars presence, Biuret test for the detection of protein present, and emulsion test for lipid detection. The two food samples were tested simultaneously for the presence of macromolecules and the tests carried out gave negative results except for Benedict’s test. Under Benedict’s test, the

The purpose of this lab is to test the process of hydrolysis occurring in different macromolecules by using the biochemical tests. This lab also indicates the hydrolysis of macromolecules when heat or acidity is applied to the molecules or compounds. The molecules that are being observed in the experiment are the polysaccharides and proteins, two main components that play an important
