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 ...

MCAT Chem Phys Question and answers 2023/2024 verified to passGenerally, how are proteins formed? - correct answer The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds - correct answer These are formed when the n-terminus o...

UNIT 1 - Quizzes And Exam, UNE Medical Biochemistry Unit 1 Test Questions And Answers. Which of the following amino acid would not be commonly found in the middle of a an α-helical domain? - correct answer. Proline. It is considered a 'helix breaker' and would not be found in an alpha helix; all other residues are nonpolar hydrophobic and could reside in a transmemebrane domain. Changes in the physiological variables listed below can alter the affinity of hemoglob...

Isomers - Answer-Two different molecules that have the same chemical formula structural isomers - Answer-Differ in arrangement of atoms. Stereoisomers - Answer-Compounds with the same structural formula but with a different arrangement of the atoms in space. Enantiomers - Answer-isomers that are mirror images of each other diastomers - Answer-stereoisomers that are not mirror images functional groups (8) - Answer-Alkyl, Hydroxyl, Carbonyl, Carboxyl, Amino, Sulfhydryl, Phosphate, Amide Al...

PeptideT or F? Peptide bonds behave as rigid planes because of partial double-bond character between the carbonyl carbon of one residue and the amide hydrogen of another residue. Correct Answer-FAlSE! B/C Hydrogen can't have a double bond, but if it stayed nitrogen it would be true. T or F? The process by which hydrophobic molecules are driven together, therefore maximizing the entropy of water, is referred to as the Hydrophobic effect. Correct Answer-TRUE! The strong electronegativity is...
