Question
Chapter 3, Problem 3CQ
Summary Introduction
To explain: The way in which structure determines the function of organic molecules such as carbohydrates, lipids, and proteins.
Introduction: The orientation of molecules and the way in which they are arranged in space determine the role they play. Through natural selection, the structures of molecules have evolved in a way that best facilitates their function.

Protein structures have several different levels of organization. In the space below indicate the type of molecular bonds that can contribute to each level of organization:
primary-
secondary-
tertiary-
quarternary-
Amino acids are monomers from which proteins are constructed. Understanding the structure and
characteris-tics of amino acids and the peptide bond that covalently links them to form peptides will
aid in understanding larger, more complex protein structures. Proteins carry out a multitude of different
and important functions. The great variety in function is accomplished through a complex and variable
polymeric structure. Comprehending protein structure will give you a better understanding of how proteins
carry out their roles.
Why
Outcomes
1. Use the acid/base characteristics (pK, data) of the 20 amino acids found in proteins to determine the
charge of an amino acid at a given pH.
2. Determine the pI of a small peptide.
3. Identify the peptide bond and describe the structural features that characterize a peptide bond.
4. Use information processing skills to draw conclusions about chemical characteristics of complex
molecules.
Plan
1. Form teams as instructed.
2. The person whose…
A mutation leads to a change in amino acid from valine, an amino acid with a nonpolar side chain, to aspartic acid, an amino acid with a polar, negatively-charged side chain. Do you think that the following levels of protein structure change? If so, how and why? If not, why not? Please frame your answer in terms of chemical bonds and interactions. (primary structure, secondary structure, tertiary structure, quartenary structure)

Would you expect albumin to still be functional? Yes the protein would still be functional because its primary structure remains intact Yes the protein would still be functional because it is used to carry lipids No the protein would not be functional because the peptide bonds would be dehydrated No the protein would not be functional because covalent bonds weaken and disrupt secondary structure No the protein would not be functional because the tertiary structure would change to maximize hydrophobic interactionsarrow_forwardBiomolecules: What are the building blocks of life? From the smallest single-celled organism to the tallest tree, all life depends on the properties and reactions of four classes of organic (carbon-based) compounds-carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates, Lipids, and Proteins are the 3 building blocks of all living things that we will focus on in this unit. These are called macromolecules (or biomolecules) because they are large molecules. They are responsible for most of the body's structure and functions, including energy storage, insulation, growth, repair, and communication. Simple organic molecules can be joined together to form all the essential biological molecules needed for life. Table 1 shows a sample elephant diet and Table 2 shows a sample lion diet. Using the background information, predict the main function of the macromolecules in their diet.
