There are four types of macromolecules; carbohydrates, lipids, proteins, and nucleic acids. The three being discussed today are carbohydrates, lipids, and proteins. Carbohydrates are compounds made up of one carbon atom, two hydrogen atoms, and one oxygen atom. are made of simple sugars, and are put into three categories. These categories are monosaccharides, which are made of one sugar molecule, disaccharides, made of two sugar molecules, and polysaccharides, made of more than two sugar molecules. Lipids are made of triglycerides, molecules made of one glycerol, and three fatty acids. Saturated fatty acids have no double bonds in their molecular structure, and unsaturated fatty acids include double bonds in their molecular structure. Proteins

Molecular Structure Lab Report: Determining Polarity Instructions: For this investigative phenomenon, you will investigate why certain substances, such as oil and vinegar, don't mix. To do so, you will combine various compounds, compare their solubility, and determine their polarity. Fill in each section of this lab report and submit it to your instructor for grading.
1. What type of macroscopic evidence for chemical change did you observe during this experiment? Give at least three different examples. (15 points)
Kylinn Walston RADT 3143 Chapter 1: Cellular Biology 1-1. Explain how the structure of the plasma membrane influences the movement of oxygen, carbon dioxide, and sodium ions. a. The plasma membrane is extremely important because of its multi-functionality to each cell, it is what keeps the cell complete. The membrane structure is determined by the lipid bilayer, and proteins determine the membrane functions. The membrane has a lipid bilayer containing hydrophobic and hydrophilic regions. This bilayer blocks hydrophilic substances from passing while still allowing water diffusion.
In order to learn more about macromolecules, we performed an organic compound experiment. The purpose of this experiment is to find and test the presence of carbohydrates(Starch & Sugar) and proteins in different food using tested distilled water as indicators(independent variable). Food that will be tested in this experiment are cookies, milk, hot dog, pretzels, applesauce, cake mix, popcorn, and potato. My hypothesis is that if the food listed are tested for carbohydrates and proteins, then most of them with the exception of water, will be positive. Materials that will be used in this experiment are 8 regular test tubes, cookies, milk, hot dogs, pretzels, applesauce, cake mix, popcorns, potatoes, tap water, 500ml pyrex measuring cup, Benedict’s solution, Biuret solution, and Iodine solution.
All dietary fats stem from the plant and animal based foods that
All enzymes are under the class of protein biomolecule. Amino acids are the basic units that are combined to make up an enzyme. The biomolecule that stores information is a Nucleic Acid. The specific 3-D region within an enzyme is called the active site. The chemical
Particles are labeled in many ways. One way particles are referred to be as atoms (elements). They’re identified by their properties, number or protons and neutrons and atomic number. Another way particles are referred are as molecules (covalently bonded- nonmetal to nonmetal). For example, water is a molecule because it’s composed of nonmetals.
Testing for the Presence of Macromolecules in McDonald’s Happy Meals Clayton Wagoner MST Biology White 4 duPont Manual High School Introduction Carbohydrates, lipids, proteins, and nucleic acids are organic molecules found in every living organism. These macromolecules are large carbon based structures. The macromolecules are assembled by joining several smaller units, called monomers, together through a chemical reaction called dehydration synthesis. The resulting polymer can be disassembled through the complementary process called hydrolysis.
Alexandra Fowler Due: 10/25/2015 Metabolism Exam Answer the following questions as completely and concisely as possible. Some answers may be a single word, but for more detailed responses, keep you answer to 3 sentences or less. What is the electron donor of an organism growing chemorganotrophically? The electron donor of an organism growing chemorganotrophically is an organic compound such as glucose, acetate, etc.
11. Explain how certain amounts and types of food can affect hunger and satiation. (max. 2 marks) The type of macronutrient a person consumes affects hunger and satiation, for instance, proteins have the strongest effects of satiation compared to carbohydrates and fats. Also, solid products that are rich in water and fibre have greater satiety values rather than those that don’t contain these characteristics.
Introduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).
“Life is meant for spectacular adventures. Let your feet wonder, your eyes marvel, and your soul ignite.” Since finishing my science fair experiment, I have been looking at new experiments and ways to further my project on slime molds. In the future, I would like to do an experiment using slime molds and how they grow in different surroundings. Specifically, I would like to see how Physarum Polycephalum reacts to different lighting and how/if it reacts to different sounds.
A slime mold is an informal name given to several kinds of unrelated eukaryotic organisms that can live freely as single cells, but they can come together to form multicellular reproductive structures. They were originally classified as fungi but they are no longer considered part of that kingdom any more. The acraiceae have a common characteristic of all forming a simple fruiting structure from the emergence of a unicellular amoeboid stage followed by a multicellular pseudoplasmodial stage. Stalk cells and spores are differentiated from the cells that develop in the fruiting structure. Sorocarpic amoebae also referred to as cellular slime molds, are heterotrophic amoeboid organisms.
Each DNA molecule is made up of two strands which intertwine to form a double helix. The form of the stucture which looks like a ladder is each nucleotide base is a DNA strand which links with another nucleotide base via hydrogen bonds in a second strand of DNA. The bases cross link in a certain order such as A adenine will only link with T thymine and the other way around then C cytosine will only link with G guanine and the other way around. When reproduction is formed from parents to off spring more genetic materials are needed the 2 stands unzip and enzymes add new bases to each which then form 2 new strands. Different segments of a DNA molecule code for different characteristics in the body.
