neutral fats, waxes, phospholipids, and glycolipids. The fatty acids with no carbon-carbon double bonds are called saturated. The ones that have two or more double bonds are called polyunsaturated. Proteins Proteins are large biomolecules, or macromolecules. They are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. Eight amino acids are essential

| | | | Exploring the Effects of Enzymes on Fat Using Phenol RedVeronica ChengSBI 3U0Turner05 December 2014 | | Introduction Enzymes are proteins which help break down chemical substances such as other proteins, carbohydrates or fats that are necessary for life (Novozymes, 2014). In this experiment, the effects of water, pancreatic juice, and trypsin solutions were observed on milk. The use of the phenol red indicator helps detect the pH level. The lower pH level will cause the colour

Why We Study the Cell and Its Components The cell is the basic unit of all living organisms. Some organisms like bacteria have only one cell while other organisms are multi cellular. It is important to study the cell and its components because it enables understanding of our own life and opens up windows of opportunity for the future generations. Understanding cells and their component functions allows for better understanding of disease and the possibility of cures or better treatment options

579 Atomic force microscopy and other scanning probe microscopies Helen G Hansma and Lía Pietrasanta The highlight of the past year is the unfolding and refolding of the muscle protein titin in the atomic force microscope. A related highlight in the intersection between experiment and theory is a recent review of the effects of molecular forces on biochemical kinetics. Other advances in scanning probe microscopy include entropic brushes, molecular sandwiches and applications of atomic force microscopy

virtual chemistry book. This theory differs from the Induced Fit theory, which states that when a substrate binds to the active site, the active site’s shape slightly changes to perfectly fit the substrate. Just like a protein, the class of macromolecule that an enzyme belongs to, the function of an enzyme depends greatly on its tertiary structure. If the structure of an enzyme changes, the shape of its active site changes also. That means the enzyme will not being able to bind with the substrates

indicative tests using chemical reagents on the substance. The indicators allowed the team to narrow down the possibilities to find out the contents of Mr. Bean’s last meal. Indicators are chemical reagents that help identify the presence of certain macromolecules in a solution. The team specifically tested for the presence of starch, monosaccharides, protein, and lipids; there was a possibility for each of the four to have been present in Mr. Bean’s dinner. The investigators initiated the test for protein

Structure Analogies a) Nucleus- The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. These two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). b) DNA- It is a molecule that stores genetic information required for the development of the body and the control of

Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates, lipids, and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia, 2012). Many are structural components of bone, muscle, hair, tissue, etc. Others are enzymes that speed up cellular reactions. All proteins are made up of amino acids (Johnson, 2010). The purpose of this

Chemistry of DNA The chemistry of DNA (deoxyribonucleic acid) is not as mysterious as some make it out to be. DNA is simply the hereditary material in all of living organisms; the biological instructions that make each species unique (National Human Genome Research Institute, 2012). Every part of our bodies contains tiny cells of DNA and within the nucleus of these cells is the information of hereditary. Nucleic acids are the building blocks of information storage; DNA and RNA (ribonucleic acid)
