Peptide linkage Study guides, Class notes & Summaries

What are the four levels of protein structure? - Answer-primary, secondary, tertiary, quaternary primary structure - Answer-The first level of protein structure; the specific sequence of amino acids making up a polypeptide chain. secondary structure - Answer-The second level of protein structure; the regular local patterns of coils or folds of a polypeptide chain. tertiary structure - Answer-The third level of protein structure; the overall, three-dimensional shape of a polypeptide due ...

what residues are connected through the α helices hydrogen bonds? the hydrogen bonds occur between the H atom of the electronegative N of a peptide linkage and the electronegative carbonyl O atom of the fourth amino acid of the amino-terminal side of that peptide bond how many amino acids are present in a turn of the a helix? 3.6 describe the α helical structure. rigid and rodlike

The second messenger in the signaling cascade initiated by glucagon is: correct answer: cAMP Explanation: The second messenger for glucagon is cAMP. Review Module 2 GPCR signaling cascades When insulin is bound to its receptor an autophosphorylation event occurs and the IRS binds these phosphorylated sites through interactions with the: correct answer: SH2 domain Explanation: SH2 domains bind with phosphorylation sites and allow for docking of the IRS with the insulin receptor. Insulin...

Infants that have lived long enough to have been fed or to have breathed accelerates decomposition Organic compound found in plants and animals, which can be broken down into amino acids protein Stitches used to hold the mouth closed mandibular suture The lumen is bluish when filled with blood and will collapse when cut vein Continuous injection of arterial solution with drainage taken at intervals is called continuous Wound characterized by irregular tear...

Small-molecule antigen requires covalent linkage to a larger carrier to stimulate adaptive immune response. The process is achieved in collaboration between hapten-specific B cells and carrier-specific T cells. This is the basis of developing conjugated vaccines. - What is the hapten-carrier effect? SEB and SEC from Staphylococcus aureus cause food poisoning. TSST from Staphylococcus aureus and SPE-C from Streptococus pyogenes cause toxic shock syndrome. - What are the common superantigens ...

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...
