Concept explainers
To calculate: The number of ten different residue peptides constructed from eight amino acids.
Concept introduction: Protein is made up of one or more amino acids linked together to form a chain. The building blocks of the protein is called amino acids. In early hypothesis, the life forms used only eight different amino acids to build small peptides. The eight essential amino acids are isoleucine, leucine, methionine, lysine, histidine, phenylalanine, tryptophan, threonine, and valine. Amino acids are termed as residues if they release a hydrogen ion from the

Explanation of Solution
Explanation:
The sequence of amino acids forms primary structure that are linked together by peptide bonds. A large number of different protein molecules can be constructed using eight different amino acids with ten different residues. For a protein of n residues, there are 8n possible sequences. The single polypeptide chain of small protein molecule consists of 10 residues. Therefore,

- Help me understand how carbon disulfide leads to toxicity in the brain, using terms like distal axonopathy, neurofilaments, covalent cross-linking, adducts, etc.,...please intuitively explain what is happening and where and the effects of it. For example, I know that CS2 reacts with amide and sulfhydryl groups on proteins, but what proteins exactly and where are they located?arrow_forwardWhat is the standard free energy change (in kJ/mole) of the spontaneous reaction between Oxygen and NADH to form H2O2 and NAD+?arrow_forwardRedox Chemistry: Give standard free energy changes expected for the following reactions:-Succinate -> fumarate (using FAD/FADH2)-Oxaloacetate -> Malate (using NAD/NADH)-NADH --> NAD+ (using FMN/FMNH2)-CoQ --> CoQH2 (using Cytochrome C)arrow_forward
- Give examples of balanced redox reactions that match the following:-Catabolic-Anabolic-Oxidative-Reductivearrow_forwardIf there are 20uM of a GLUT2 transporter on the surface of a cell, each able to move 8 per second, and 50mM glucose outside of the cell, what is the flux into the cell in mM/sec?arrow_forwardA transporter is responsible for antiporting calcium and glucose. The transporter brings glucose into the cell and sends calcium out of the cell. If blood [calcium] = 2.55mM and intracellular [calcium] = 7uM, blood [glucose] = 5.2mM, and intracellular [glucose] = 40uM, what is the free energy of transport? Assume a membrane potential of 62mV (negative inside).arrow_forward
- An ATP-coupled transporter is used to import 1 phosphate from the extracellular environment. Intracellular phosphate exists at 65mM, while it is 2mM outside.Assume a free energy change of ATP hydrolysis of -42.7 kJ/mol. What is the net free energy change of the coupled reaction? Assume a membrane potential of 70mV.arrow_forwardAnother transporter brings 3 chloride ions into the cell. Outside, chloride has a concentration of 107mM, and 4mM inside the cell. Assuming a membrane potential of 62mV (negative inside), what is the free energy of transport of these ions?arrow_forwardFor the Oxaloacetate -> Malate reaction, assume the normal ratio of NAD/NADH, what is the maximum ratio of Malate/Oxaloacetate that will allow reaction progress?arrow_forward
