Provide 5 major properties and their subunits for: Carbohydrates Proteins Lipids Nucleic Acids
Compare the structure of the four major biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids) and explain how the distinct structure of each type of molecule enables it to carry out its particular function.
Why are carbohydrates, lipids and nucleic acids not as functionally diverse as proteins?
Which of the following macronutrients are least hydrophilic? Lipids Carbohydrates Nucleic Acids Proteins
1. List/describe similarities of proteins, carbohydrates, and nucleic acids. 2. Lipids are generally smaller than and don't have true monomers like the other 3 types of macromolecules; but how are they similar to proteins, carbohydrates, and nucleic acids?
Proteins have many diverse functions. Carbohydrates, nucleic acids and lipids do not have diverse functions in a cell. Proteins are polymers of amino acids. Discuss how the structure of amino acids allows proteins to perform so many functions.
Match the macromolecule categories with their correct function: lipids, carbohydrates, nucleic acids, proteins functions: 1. energy source - cell markers 2. inheritance - protein synthesis 3. energy source - hormones - chemical signals 4. enzymes - channels - structural support
Compare and contrast the bonds involved in formation of macromolecules, including proteins, nucleic acids and carbohydrates, with those involved in formation of macromolecular assemblies of lipids, e.g. membranes.
50) Water is formed during the synthesis of: a) proteins b) lipids c) carbohydrates d) nucleic acids e) all of the above 51) Amino acids are held together by: a) ester bonds b) glycosidic bonds c) pasteur bonds d) all of the above e) none of the above 52) Sugars are held together by: a) ester bonds hydrogen bonds b) peptide bonds c) all of the above d) none of the above e) Nucleotides within the same strand of DNA...
