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…
What life uses proteins for? (functions of proteins)
Describe protein structures.
Describe the alpha helix and the beta sheet structure of proteins.
Which structure is the most important in the function of a protein?
Describe what can affect the protein structure.
Why the structure of a protein is important?
Describe the four levels of protein structures. Include information about the bond between amino acids, and for the third level of protein structure, discuss the other types of bond found there. Make sure you include hydrogen bonds, ionic bonds, and an example of covalent bonding. Explain why not all proteins form a quaternary structure.

- Provide the smallest molecular unit of most lipids, proteins, and nucleic acids. Keep in mind that lipids are a little tricky.arrow_forwardDetermine whether the following statements describing protein structures is correct or incorrect. CORRECT INCORRECT Proteins in a primary structure consist of a simple polypeptide chain. Interactions between the R groups in amino acids form tertiary structure. Secondary structures are formed by multiple polypeptide chains The two types of secondary structures are the alpha and beta pleated sheetsarrow_forwardSelect the true statements about protein secondary structure. In an a-helix, the side chains are located on the outside of the helix. The secondary level of protein structure refers to the spatial arrangements of short segments of the protein. In a B-pleated sheet, the side chains are located between adjacent segments. Peptide bonds stabilize secondary structure. The x-helix is held together by hydrogen bonds between the amide N-H and C=O groups. Incorrectarrow_forward
- Which statement about quaternary structure is TRUE? Quaternary structure is unaffected by acids or heat. Quaternary structure is determined by the same interaction that holds an α-helix together. Quaternary structure is how prosthetic groups are held in a protein. Quaternary structure is the position of subunits in the overall structure of a protein. All proteins have quaternary structurearrow_forwardProtein 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-arrow_forwardDiscuss using your own words and illustrations the organisation of a protein, from its linear amino acid sequence, to its final three–dimensional configuration, which may include one or more polypeptides. Include what types of bonds help to stabilise each structural level, from primary through quaternary structure.arrow_forward
- Carbon’s versatile bonding behavior allows it to form a variety of structures and are the base of all macromolecules. The diagram shows the structure of an amino acid, which is the monomer unit for proteins. Identify and describe the polymer structures of a protein that constitutes its unique conformation.arrow_forwardCarbohydrates can be polymers, just like proteins and nucleic acids, we have studied, so far. Yet carbohydrates differ from proteins in some aspects, what are they? Explain with some examples. How do the presence of carbohydrates influence the behavior of proteins when they are covalently attached?arrow_forwardwhich of the following is correct about the structure of proteins? a- the number of peptide bonds is equivalent to the number of amino acid residues b- the secondary structure of proteins are mostly stabilized by hydrophobic interactions c- protiens mostly composed of polar amino acids will have an elongated (fibrous) tertiary structure d- the quaternary structure of a protein is formed between or among similar polypeptides onlyarrow_forward
- Which of the following statements about protein is correct? (Choose three). * During polypeptide bond formation, the hydroxyl group is lost from its carboxyl group of one amino acid and a hydrogen atom is lost from its amino group of another amino acid Amino acid sequence of a protein determines its three-dimensional shape. pH change, organic solvents, heat, and chaperones are the factors responsible for the denaturation of proteins. Secondary protein structures such as alpha helices and beta pleated sheets are formed by multiple polypeptide chains. Different amino acids contain different side chains which make them unique.arrow_forwarddraw a model of a protein Include a brief description of your protein - what protein is it? what details can you share about this protein (for example, a description of it's shape, how big it is (either in kilodaltons or number of amino acids), what is its function)arrow_forwardDraw the basic structure of a named lipid and identify its 2 main types of component.arrow_forward
