You can remember which nitrogenous bases can form hydrogen bonds using a simple mnemonic device. Verified answer. A positive test for proteins would be when the sample being tested, which contains protein macromolecules, turns a pink or purple hue, after the indicator Biuret reagent is added to the sample (Humagain, 2018). the Biuret reagent was added to them, because it is known that these two foods do contain. This ensures that the molecules head is always oriented towards water whether that is the cytosol of the cell or the external environment. Triglycerides are simply fatty acid molecules bound into a larger molecule with glycerol a three-carbon alcohol. (Humagain, 2018) It is also possible that the results of these two tests Starch molecules such as amylose found in potatoes are essentially huge branching structures that fill cells with energy. Retrieved from http://www.biologydiscuss ion .com/lipids/tests/qualitative-and-quantitative-tests-forlipids/13050. The Benedicts reagent is only able to recognize the presence of monosaccharides and some disaccharides, so it would not be useful when testing food samples that contain polysaccharides or certain disaccharides that it is unable to recognize (Benedicts reagent test, 2017).

In addition, to have a balanced, healthy diet, people must consume foods, alike the food samples used in this lab, that contain a variety of essential biological macromolecules. are there any other macromolecules apart from carbs ,fats,protiens and nucleotides. Quiz 1. More importantly, the nitrogenous bases create the double-helix structure of DNA through their ability to form hydrogen bonds. Some structural carbohydrates even have cross-links between the fibers, adding another layer of strength to a molecule. )), Science Explorer Physical Science (Michael J. Padilla; Ioannis Miaculis; Martha Cyr). size, they are classified as, How do you build polymers from monomers? Unit: Macromolecules. DNA is stored in the nucleus as a double helix. Dehydration synthesis reaction between two molecules of glucose, forming a molecule of maltose with the release of a water molecule. These results display that only the cream, yogurt, and cheese contained proteins, however, the cracker and raisin did not contain proteins. Lipids fit that description, but they aren't polymers because they are made up of smaller units of different kinds (like glycerol and fatty acids) rather than monomers that repeat themselves. The ribosome then creates a new protein molecule by matching transfer RNA molecules to every 3-nucleotide sequence, known as a codon. AP Bio: Solutions containing these macromolecules were tested for carbohydrates using Benedicts reagent, lipids on brown paper, proteins using Biuret reagent, and starch using Lugols solution. Only the cracker tested Overall, these results indicate that different foods contain different varieties and combinations of macromolecules. Discussion However, as you connect more and more carbohydrate monomers, you can create substances with many different properties.

It is revealed that only the cheese did not contain sugar macromolecules, whereas the cracker, cream, yogurt, and raisins did contain sugar macromolecules. This can help hold multiple polypeptides together in a large quaternary structure. Monomers are the building blocks of the four basic macromolecules of life- monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA. So, we can conclude that a biological macromolecule is a large organic compound made up of smaller molecules. There are three types of lipids that are most important to life: fats (triglycerides), phospholipids, and steroids. by DepEd Resources. Biological Macromolecules and Enzymes Student Name Blair Cournoyer November 15th, Large biological molecules often assemble via. These groups are what gives each amino acid its unique functionality. For instance, several amino acids have charged R-groups. In addition, to have a balanced, healthy diet, people must consume foods, alike the Solutions containing these nucleotide: a monomer of nucleic acids; contains a pentose sugar, a phosphate group, and a nitrogenous base. Combined, these molecules make up the majority of a cell's dry mass. A positive test for lipids would be when the sample being tested, which contains lipid macromolecules, leaves a translucent, oily film on the brown paper in which it was tested on (Kumar, n.d). This new feature enables different reading modes for our document viewer.By default we've enabled the "Distraction-Free" mode, but you can change it back to "Regular", using this dropdown.
