Macromolecules are a essential part of life, which make up living organisms. A macromolecule is a large molecule that is joined by tiny molecules by forming new bonds. This processs is called dehydration synthesis, and it is when a water molecule is removed and a covalent bond is formed. Breaking this bond is called hydrolysis, it is the the addition of a water molecule and releases energy. Examples of macromolecules would be nucleic acids, proteins, and polysaccharides (2 or more sugars). The biological components are composed of starches, proteins, lipids, and nucleic acids. Starches consisit entirely of glucose monomers and are joined by glycosidic linkages, only found in plants. Lipids are a large group of biological molecules that …show more content…
Monosaccharides are the simplest form of a carbohydrate, and serve as a monomer for disaccharide (2 or

more monossacharides) and polysaccharide (3 or more monossacharides). Examples of a monosaccharide is glucose, fructose, and galactose. Meanwhile, disaccharides are joined by a glycosidic linkage formed by a

dehydration reaction. Examples of disaccharides are sucrose, lactose, and maltose. Lastly, a polysaccharide is a polymer of 3 or more sugars formed by a deydration reaction. Examples of polysaccharides are starch and

glycogen. In this experiment, central sugars can be found by utilizing Benedict's test. Proteins are made of carbon, hydrogen, oxygen, nitrogen, and from time to time sulfur. Proteins are covalently maintained in chains as

polymers of amino acids. These bonds are called peptide bonds. Peptide bonds are the covalent bond between the carboxyl group and one amino acid and the amino group on another formed by a dehydration reaction.
Amino acids related together edge a polypeptide called a protein. Several proteins are other than real primary purposes. The Benedict's test is utilized to discover either amino acids or proteins. The Biuret's test is for

This protein using CuSO4 and NaOH should result in a color change from purple to a darker purple color. Lipids are macromolecules that are generally insoluble in water. Lipids are made of carbon, hydrogen, and

oxygen. They are shown as fats or triglycerides. Oils are fluid at room temperature and are called unsaturated. Strong fats are submerged. Lipids are found in cell films and are a huge energy source. By utilizing the Sudan III

test the domain of lipids can be found. Sudan is a red dye that forms hydrophobic interactions with the hydrocarbon chains of lipids.

In this lab, an experiment was conducted to check for the locale of specific macromolecules in known substance. We believed that iodine test for starch, would be that glucose and starch held simple sugars, but it

did not. The hypothesis was that color would change blue-black on the starch sample and not on the sugar samples. The hypothesis was that the potato contained starch and the onion did not. The biuret test for protein

tested for both amino acids and protein. For this experiment the only hypothesis was that the starch sample would more than likely not to change color. Lastly, Sudan III test hypothesis was that color would change

    Title: Alexandra Whitaker, Ms.Dayton, 12/23/16, 2.03 lab permeability Objective(s): The main purpose is to find out if plastic bags are permeable to starch and, or, iodine. Also, to find out wither potatoes are hypotonic, hypertonic, or isotonic by testing the different amounts of sucrose solutions Introduction: The necessary background information needed for this lab is the definition of osmosis, diffusion, active transports, passive transports, permeability, concentration, tonicity, and to now the scientific concepts of hypotonic, isotonic, and hypertonic. Hypothesis: For part 1 my hypothesis is: That the starch will diffuse across the plastic bag and react with the iodine and will have a color change to the water to imply the reaction…

These three tests are going to examine different properties of macromolecules such as their bonds, and functional groups to identify the solution as one of the four macromolecules. The iodine test is used to determine the presence of polysaccharides such as starch and glycogen in the solution (Harisha, 2006).…

    Which would include lipids, proteins, nucleic acids, and carbohydrates. A lipid is a group of naturally occurring molecules, some example of lipids are fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and more. A protein is a large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. A nucleic acid is a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain. A carbohydrate is biological molecule consisting of carbon, hydrogen and oxygen atoms.…

    The four macromolecules present in all living organisms are carbohydrates, lipids, proteins, and nuclear acids (Daempfle, 2016). Carbohydrates provide energy. Like carbohydrates, the main function of lipids is to store energy long-term. Proteins are the most common macromolecule in livings systems; they play various roles in our bodies from hair, nails, and skin to having functions in chemical reactions within cells. Nucleic acids play a vital role in the formation of proteins which perform many essential functions for cells.…

The effects of structural proteins are the destruction of secondary and teritary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure remains the same after a denuration process. These proteins have functions enzymatic functions signaling functions and rarely be used to store energy.…

    In experiment 2.1, absorbance readings for both heated and unheated corn and tapioca starch were taken. For both starch’s the heated results came to be much higher then the un-heated as seen in Table 2.1. Iodine reacts with the amylose compound in starch where it gets trapped in the amylose coils and blue-ish colour is formed after the addition of Lugols reagent (Fennema and others 2008). The absorbance readings came out higher for heated corn starch because iodine had more amylose to react with. As corn-starch is heated gelatinization occurs where amylose is released since the starch granule is disrupted.…

    Carbohydrates can be classified into three groups: monosaccharide, disaccharides and polysaccharides. Monosaccharide is simple sugars, and its main representatives are glucose (manufactured by plants during photosynthesis), fructose (found in honey) and lactose (found in milk). The union of two monosaccharaides forms disaccharides, and his best-known representatives are sucrose and lactose. Sucrose consists of a glucose molecule and a fructose molecule. Sucrose is the sugar we consume at home, which we use in our coffee, juices, pastries etc.…
