Step by step
Solved in 3 steps
- How can a protein’s potential function be determined from a protein’s primary structure? I assumed this was not possible, I thought its function was determined from its 3-dimensional structure only. Thank you for explaining this.The protein illustrated in the attached picture was isolated from a superhuman being. Scientists theorized that it was the source of power of its power. 1.Give the name of the protein using the one letter symbol.This image shows the tertiary structure of a protein segment. Tertiary structure results from different interactions, or forces, between groups. Move the example of each force to the appropriate description on the protein. Then, identify the major force controlling tertiary structure. (Need help) It says I'm wrong.
- The following figure is a diagram (cartoon or caricature) of the structure of a protein. What types of secondary structure are observed in the molecule? Is it a globular protein or a fibrous one?Attach an amino acid with the “-SH” functional group below. (not super long answers please) What is the name of the -SH functional group? What level of protein structure is determined by these amino acids? ExplainAll proteins have primary (1°), secondary (2°) and tertiary (3°) structure. In addition, some (but not all) proteins exhibit quaternary (4°) structure. Explain quaternary structure and why only some proteins exhibit that level of structure.
- 1.Leucine is shown below. Suppose this amino acid was used to form the protein sequence Arg-Phe-Leu-Met-Pro. Select any atom that will be part of the protein backbone 2.This cartoon pf the protein hormone insulin illustrates what spaces of insulins structure? primary structure secondary structure tertiary structure quaternary structureBased on this table: 1) What is the difference between subunit mass and native mass? 2) How do you tell what the likely quarternary structure of the protein is? (heterotrimer, homotrimer, etc.)3c) The 3 structure of a protein incorporates any 2 structure the protein has, but results primarily from interactions between amino acid side groups. Name two different amino acids whose side groups could participate in each type of interaction given below under physiological conditions (pH 7.2-7.5). Ionic bonding: Hydrophobic clustering: Hydrogen bonding:
- Which of the following statements are correct about the native state of a protein (select all that apply)? A. Polar sidechains commonly interact with water B. Hydrophobic amino acids tend to be on surface of protein C. The sidechains of polar amino acids are most commonly found in the central core of a protein D. Formation of an alpha-helix is primarily driven by hydrogen bonds between the protein main chain, not sidechains. E. Secondary structure is largely driven by hydrophobic interactionsThe simplest form of the Ramachandran diagram is calculated by ignoring hydrogen bonding, interactions with water, and the hydrophobic effect. Why is this simple form of the diagram still an effective predictor of protein backbone conformation?This cartoon represents the quaternary structure of proteins and each color of the different shape represents a different subunit. 1. How many N-terminus are there in this cartoon?
