Peptide amide bonds - Study guides, Class notes & Summaries

van der Waals correct answer: -weakest (short lives) but lots could strengthen the bond -furthest distance -form as a result of hydrophobic interactions -strength depends on the size of the atoms and the distance between them -cannot be closer than the Van der Waals contact distance or else positively charged nuclei will repel each other (energy= 0) Proteins correct answer: main action molecule of the cell (Most chemical processes of the body are carried out by proteins) -classified in...

ACS Biochemistry Final Exam Questions and Correct Solutions 2024 pKa (chapter 3) - Answer -measure of the tendency of a group to give up a proton (acidity); tendency decreases tenfold as pKa increases by one unit thioester bond (1) - Answer -compounds with functional group C-S-CoA-C (eg, in acetyl-CoA) zwitterion (3) - Answer -dipolar ion with both positive and negative groups but overall neutral charge; can act as either an acid or base Isoelectric point (pI) (chapter 3) - Answer -the ch...

primary structure of protein correct answer: linear sequence of amino acids in the polypeptide chain secondary structure of protein correct answer: alpha helix and beta pleated sheet alpha helix correct answer: formed when the carbonyl group of peptide bond forms a hydrogen bond with the amide nitrogen of another peptide 4 aa down the chain; proline is not commonly found among these structures beta sheets correct answer: can be parallel or antiparallel peptide chains forming rows or...

pKa (chapter 3) - measure of the tendency of a group to give up a proton (acidity); tendency decreases tenfold as pKa increases by one unit thioester bond (1) - compounds with functional group C-S-CoA-C (eg, in acetyl-CoA) zwitterion (3) - dipolar ion with both positive and negative groups but overall neutral charge; can act as either an acid or base Isoelectric point (pI) (chapter 3) - the characteristic pH at which the net electric charge is zero SDS - Sodium Dodecyl Sulfate (chap ...

AAMC FL2 C-P Questions Review 2023 What atom is the site of covalent attachment of AMC to the model tetrapeptide used in the studies? A. I B. II C. III D. IV - This question is A because AMC is attached to the peptide on the carboxyl side. This suggests that an amide linkage involving the N atom in AMC is used to covalently attach the fluorophore to the peptide. The passage says AMC is removed from a peptide via peptide bond hydrolysis. Thus, AMC must form a peptide bond with t...
