The Four Main Macromolecules Interestingly enough‚ all cells that build up an entire organism‚ such as the human body‚ only consist of water‚ inorganic ions‚ and organic compounds as three dominant components. Together‚ water and inorganic ions such as Sodium‚ Magnesium‚ Calcium‚ Phosphate‚ etc. make up around 70% of the cell’s mass‚ while organic compounds make up the rest. Unlike its other two counterparts‚ organic compounds contain carbon-hydrogen reactions that allow them to create‚ sustain‚

Macromolecules BCM261/BCM262 Anonymous Student #2 Aim The purpose of this lab was to use the scientific method to identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

IDENTIFICATION OF SOME MACROMOLECULES | | INTRODUCTION Dehydration-synthesis is a reaction that occurs to form different types of macromolecules. It is a reaction that leaves a macromolecule structure along the lines of developing its own specific function in a living organism. The 4 most common ones are carbohydrates which includes monosaccharides and polysaccharides‚ lipids‚ proteins and nucleic acids (Mack 2012). Scientists identify different types of macromolecules to achieve a better

test for starch macromolecules occurs when the solution turns dark brown when Iodine solution is added. 2. If there is glucose in the substance‚ the substance turns to an orange-yellow colour when Benedict’s Solution is added to it. The colour of the glucose solution when it is mixed with Benedict’s solution with heat is orange-yellow‚ while all of the sample solutions turn into a light blue or purple colour. We can therefore deduce that a positive test for glucose macromolecules is when the colour

compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size. Atoms have diverse characters that depend on the atoms electronic configuration. Carbons unique configuration allows it to form bonds with up to four other atoms‚ and gives carbon a covalent compactivity with many other

considered alive. These requirements are macromolecules‚ it needs to have metabolism‚ and be able to reproduce. If something has all of these things then it can be considered alive. The first requirement is that it has to have cells. Beings also need macromolecules because they need energy. The four macromolecules are carbohydrates‚ lipids‚ proteins‚ and nucleic acid. Macromolecules are used for energy. A great example of this is humans an their intake of macromolecules. For the average human‚ 55-65% of

composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed. ABSTRACT Tissue types have a variety of compositions‚ and one way to describe these differences is by comparing macromolecule content. The four macromolecules – lipids‚ proteins‚ carbohydrates‚ and nucleic acids – can be quantified and analyzed.

Test for the Presence of Macromolecules Introduction In this experiment‚ we are trying to identify the presence of macromolecules in certain solutions. As in our daily lives‚ macromolecules are the essential nutrients that we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and

Introduction The purpose of this experiment was to identify the presence of macromolecules by using various positive and negative controls. The principle building blocks of living organisms are essentially constructed by carbon-containing molecules in cells. (Alberts‚ 2009) The macromolecules including lipids‚ carbohydrates‚ proteins‚ and nucleic acids contribute to the most distinctive properties on living organisms. Macromolecules are known as polymers which are constructed by small organic subunits
