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...

MMSC407 Exam 2 Questions with All Correct Answers What is the structure of an amino acid? - Answer-Amino group (N-terminus on left), Carboxyl group (C-terminus on right), Side chain (R-group on bottom) Amide bonds - Answer-The peptide bonds that link amino acids in a protein (C-NH2) Carboxyl bonds - Answer-C-COOH Amide bonds are... - Answer-Basic Carboxyl bonds are... - Answer-Acidic What forms are all amino acids in? (except when R=H) - Answer-Chiral L-stereoisomer form How...

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...

How are amino acids joined? correct answers Amino acids are joined covalently through peptide bonds involving the carboxyl group of one amino acid and the amino group of another amino acid 4 Levels of protein structure correct answers Primary, secondary, tertiary and quaternary Primary Structure correct answers The linear arrangement of amino acids within a peptide, polypeptide or chain. But it tells nothing of the three-dimensional structure Secondary Structure correct answers Localize...

Polysaccharides (saccharides are carbohydrates) correct answers Polymer of monosaccharides Peptide bond correct answers Bond between amino acid residues to form a polypeptide chain. (Amide linkage) Phosphodiester bond correct answers Bond that connects nucleotides together to form nucleic acids Glycosidic bond correct answers Any bond that links a sugar to something else Hydrogen bond donor correct answers A hydrogen bonded to an electronegative atom Hydrogen bond acceptor correct...

BCHM 307 EXAM 1 QUESTIONS WITH ANSWERS Secondary structure - Answer-the local 3-dimensional structure of the peptide backbone - there are 4 major classes of secondary structure (alpha helix, beta sheet, turns, and random coil) The alpha helix of the secondary structure - Answer-the alpha helix is a helical region of the peptide backbone that is stabilized by hydrogen bonding - carbonyl residue of each amino acid residue is hydrogen bonded to the amide group 4 residues further toward the c...

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...
