biological macromolecules answer keybiological macromolecules answer key

There are four classes of macromolecules that constitute all living matter: carbohydrates, lipids, proteins, and nucleic acids. Unlike a linear structure, this allows a cell to store as much energy in as small of a space as possible. The energy released when the food molecule bonds are broken can be used for survival. Phospholipids are different structurally compared to triglycerides and they also serve a much different purpose within organisms. 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. (n.d). Carbohydrates, nucleic acids, and proteins are often found as long polymers in nature. Provide cells with quick/short-term energy, source of dietary fiber, Glucose, sucrose, starch, cellulose, chitin, Provide cells with long-term energy, make up biological membranes, Fats, phospholipids, waxes, oils, grease, steroids, Provide cell structure, send chemical signals, speed up chemical reactions, etc, Keratin (found in hair and nails), hormones, enzymes, antibodies. protein macromolecules, turns a pink or purple hue, after the indicator Biuret reagent is added to macromolecules were tested for carbohydrates using Benedicts reagent, lipids on brown paper, the Biuret reagent was added to them, because it is known that these two foods do contain. The monomers in carbohydrates are held together by peptide bonds. Wrap-up - this is 302 psychology paper notes, researchpsy, 22. Some people consider waxes their own category, though they have a structure very similar to triglycerides. lipid. test negative for them, even if they do happen to contain lipids. solutions. .. wanted to grow healthy hair? Every carbon in the chain is bound to at least 2 hydrogens, leaving no room for double bonds between carbon atoms. A large molecule made of repeating subunits (monomers). So, not only does the active site need to have the right R-groups exposed, but the protein must also have the right sequence of amino acids to fold into the proper shape.

Short Answer questions 1.What is the relationship between glucose, fructose, and galactose? The objective of this lab was to identify and investigate the macromolecules found in different food samples. How are Hydrocarbons related to Macromolecules? One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released as a new covalent bond forms between the two glucose molecules. The base attached to this structure is cytosine, one of several bases that can be attached to a nucleotide. (Humagain, 2018) It is also possible that the results of these two tests could have been altered, due to the experimental error of cross-contaminating substances.

In science, using the word "all" is risky because there are invariably exceptions to any rule. 75. BUILDING A MACROMOLECULE: Explain the relationship between monomers and polymers and explain how these molecules are related to the "unity and diversity of life." Explain how monomers are linked together and how they are disassembled (include an illustration of each process) Use the diagram below and then answer the following questions. There are many triglycerides found in nature, with both saturated and unsaturated fatty acids in their structure. (In a cell, nucleic acids actually aren't polymerized via dehydration synthesis; well examine how they're assembled in the article on, In the body, enzymes catalyze, or speed up, both the dehydration synthesis and hydrolysis reactions. However, it is possible that there were not enough protein peptide bonds, causing the solution to show no apparent colour change, since the Biuret reagent relies on peptide bonds in proteins to change colour. After reading the key terms, I am a little bit confused.. to my understanding, monomers are the makeup of polymers is that correct? https://en.wikipedia.org/wiki/Allotropes_of_carbon. The Biuret reagent relies on peptide bonds in proteins, in While the structure of each amino acid is slightly different, many amino acids bring similar properties to the polypeptides they are a part of. Nucleic acids store and transfer hereditary information, much of which provides instructions for making proteins. Direct link to Oliver's post Hey!

Structurally, this makes saturated fats very linear. (b) Glycine, a component of proteins, contains carbon, nitrogen, oxygen, and hydrogen atoms. There were four standard tests used to yogurt, and cheese solutions turned purple. For helping others in their module and to find some answer in their modules. While they have different structures and functions, they are all composed of long complex chains of molecules (polymers) made up of simpler, smaller subunits (monomers). A molecule that is a building block for larger molecules (polymers). In my textbook, it is written that fatty acids are the building blocks of lipids then why don't we classify lipids as polymers? possessed. positive for starch. Differences in saturation determine the structure and function of lipids. Most macromolecules are made from single subunits, or building blocks, called monomers. Polymers are comprised of monomers. The hydroxyl groups on glycerol react with the carboxyl head groups of each fatty acid. I think what you can say is that if you can use dehydration to polymerise sugar molecules to form a chain, then you can reverse that process by hydrolysis and get the sugar molecules back. True or False: The building blocks of macromolecules are also known as "monomers". In this section, students learn about the structural components and bonds needed to create nucleic acids, proteins, complex carbohydrates, and lipids.
