Which of these statements about the tertiary structure of a polypeptide is(are) untrue? You may select more than one answer. The tertiary structure will be maintained when the solvent is changed from pure water to aqueous acetic acid. O The tertiary structure is determined in part by the formation of disulfide bridges. Hydrogen bonding interactions are responsible for formation of secondary structure but not tertiary structure, O The tertiary structure is rigid and unchanging. O Charge-charge (electrostatic) interactions can be important in the tertiary structure.
Which of the following fusion of molecules establishes the backbone of an amino acid? 1. An alpha carbon, a carboxyl/carboxylic acid group and, an amine/amino group 2. A phosphate group, an alcohol sugar like glycerol and, a saturated and an unsaturated fatty acid 3. An alpha carbon, a carboxyl/carboxylic acid group, an amine/amino group, and an R group, for example: the methyl group of the amino acid alanine 4. An alpha carbon, a carboxylic acid group, an amine/amino group and, an R group, for example: hydrogen of the amino acid glycine
Peptide bonds cannot rotate. This is because: a) the amino acid side chains are too bulky to allow this. B) Internal hydrogen bonding hinders rotation. C) interaction with water molecules hinders rotation D) the peptide bond has considerable double bond character Polypeptide chains prefer the trans conformation. This is because: a) This distances hydrophilic groups from hydrophobic groups b) this minimizes crowding of side chains c) This brings hydrophilic groups in contact with water molecules d) This allows proteins to fold more easily Ramachandran plots indicate that protein conformation is largely a function of: a) hydrophobicity b) number of amino acids c) torsion angles d) arrangement of prosthetic groups
Within a naturally-occurring polypeptide, under neutral pH conditions (pH = 7.0), which of the following amino acids always has a negatively charged carboxyl group? the first amino acid in the primary structure histidine lysine arginine the last amino acid in the primary structure
The peptide bond is a stronger bond than that of esters. Whatstructural feature of the peptide bond gives it additional bondstrength?
Identify an amino acid that complies with the following characteristic: (VWrite the COMPLETE name) Contains a side chain with a thioether bond
How do the standard amino acids differ from one another? in whether or not the amino group is chiral in the number of chiral carbon atoms between the carboxyl group and the amino group in the identity of the R group (side chain) in whether or not the carboxyl group is chiral
Give the name and structure of at least two examples of each of the following: Heterocyclic amino acid Aromatic amino acid Neutral amino acid Acidic amino acid Basic amino acid Sulfur-containing amino acid
An amino acid structure contains a -COOH and -NH2 group in the same molecule. The -COOH group donates a proton to the -NH2 group. Because of this, the amino acid structure contains a positive charge on one atom and a negative charge on the other. What is the term used to refer to this character of amino acids? O Amphiphatic O Isoelectric point Zwitterions O Amphoteric
Amino acids attached together in a straight line structure, is called: Primary structure Quaternary structure Secondary structure Tertiary structure
Identify an amino acid that complies with the following characteristic: (Write the COMPLETE name) Contains an amide side chain
Which functional groups of amino acids are involved in the formation of a peptide bond? O The carboxyl groups of both amino acids O The amino groups of both amino acids O The side chains of both amino acids A carboxyl group of one amino acid and the amino group of another A carboxyl group of one amino acid and the side chain of another
