conditions, diamonds are produced with a temperature range of 900 and 1300 degrees Celsius. Then put under pressure of 725,000 pounds per square inch. (World of Carbon, n.d.) Diamonds have these properties because they are macromolecules; (Encyclopedia of Britannica n.d.) macromolecules are atoms that join together and from on big molecule. In which they also have a strong bonds. Each Carbon atom has a valence electron of four, diamonds are made out of units of carbon atoms joined together using the

There are four macromolecules that make up all living things. These macromolecules are proteins, carbohydrates, lipids, and nucleic acids. All of these macromolecules are formed from functional groups. The functional group hydroxyl is found in every macromolecule. All of these macromolecules except for lipids are hydrophilic. All of these macromolecules are broken down into monomers by hydrolysis reactions. Proteins have methyl groups, amino groups, and carboxyl groups. Proteins are polymers of

Macromolecules Carbohydrates are a type of macromolecule. Their subunit or monomer are simple sugars such as glucose and fructose. These are created with hydrogen bonds and are inorganic CH2OH. Glucose an example of a carbohydrates function is to provide energy for the organs to function in the body. Carbohydrates are a from of short term energy. A polysaccharide starch consists of repeating glucose molecules and has the function of breaking back down into glucose to again provide energy to the body

molecules that make up biological systems. There are four major molecules (macromolecule) found in living organisms – Carbohydrates, Lipid, Proteins and Nucleic Acids. They all have different chemical properties and can be identified by their functional groups. A chemical test that is sensitive to these functional groups can be used to identify or test for the presence of each of the macromolecules. This lab tests for major macromolecules using such tests.

that are needed to make biological macromolecules. Biological macromolecules, are large molecules (also known as polymers). A monomer is a molecule that is able to bond in long chains. Monomers are small molecules that may be joined together in a repeating fashion to form more complex molecules called polymers. Usually, polymers are organic (but not necessarily). Hydrogen bonds are responsible for the properties of water and many biological molecules. Macromolecules, that are necessary for life, include

The purpose of this lab was to use different indicators to determine what macromolecules are in different foods. We used Lugol’s solution to determine the starch content, Benedict’s solution to see the sugar content, Biuret reagent to test for the proteins, and used a paper bag to determine the lipid content. Materials: Vegetable Oil Glucose Starch from corn or potatoes Powdered egg whites Water Lugol’s solution Benedict’s solution Biuret reagent Pretzel Toast Jelly Pineapple Fat-free yogurt

Although I took biology class back in high school, I never truly paid attention or really understood the material. Taking this course helped me learn more about the scientific method, atoms the chemical bonds, the importance of water, and the macromolecules. An observation is always the first step to the scientific method. Collecting data helps understand the full detail of the experiment. A hypothesis would then need to be formed. It’s the question to be studied through experiments. Experiments

everything came from a such a simple compound in an enormous amount. In essence, the ocean gave birth to us through millions of years of evolution. Because of the chemical properties of water and our primitive atmosphere, macromolecules were allowed to form. As the macromolecules formed and combined within the ocean, the creation of the planet we now know today began.
