Question

**Glucose and Fructose Structural Comparison**

*Question:*
Glucose and fructose are both C₆H₁₂O₆. What is the structural difference between them?

*Options:*

1. Glucose is a linear molecule and fructose is a ring.

2. Glucose is a five-membered ring and fructose is a six-membered ring.

3. Fructose is a five-membered ring and glucose is a six-membered ring.

4. Glucose is found in the boat conformation and fructose is a chair conformation.

*Explanation:*

The structural differences between glucose and fructose can be attributed to their ring formations. Although both are hexoses (with the chemical formula C₆H₁₂O₆), glucose typically forms a six-membered pyranose ring, while fructose forms a five-membered furanose ring in its cyclic form. Understanding these structural variations is fundamental in biochemistry, especially in the metabolism and functional properties of carbohydrates.

Cellulose is a large polysaccharide containing many alpha(1→4) glycosidic linkages and alpha(1→6) glycosidic linkages. True or False?
Glutamine is an amino acid that has -CH₂-CH2-CO-NH₂ as its R group. The R group of the amino acid isoleucine is -CH2-CH-(CH3)2. If these amino acids were in a globular protein in aqueous solution, where would they most likely be? O Both glutamine and isoleucine would be in the interior and on the exterior of the globular protein. O Glutamine would be in the interior, and isoleucine would be on the exterior of the globular protein. O There isn't enough information O Both glutamine and isoleucine would be on the exterior of the globular protein. O Isoleucine would be in the interior, and glutamine would be on the exterior of the globular protein.
Place each charge form of alanine under the pH condition where it would be the predominant form. The pK₁ values for the carboxyl group and amino group of alanine are approximately 2.3 and 9.7, respectively. pH 11 H | H₂C-C-COO NH₂ Does not occur in significant amounts at any pH
"Potassium Bromate (KBr03) is added to flour as a softener that strengthens the texture of bread. It can do this by forming disulfide bonds between two cysteine amino acids in a reaction similar to the chemical equation given below. The function of KBr03 is to remove the 2 electrons needed to form the disulfide bond as shown in the figure below. Each of the cysteine amino acids will be in a protein chain, so the reaction binds the two chains together, giving the dough cohesion. However, potassium bromate is a proven carcinogen and is only allowed in foods in the United States because bakers will add the right amount and correct It has been assumed to meet the temperature and cooking time conditions.

The figure below illustrates the molecular structures of two fatty acids. A B H₂C The structural formula of erucic acid and behenic acid с H₂C D erucic acid behenic acid Which of the following best explains why erucic acid is liquid at room temperature but behenic acid is solid at room temperature? O OH The presence of a double carbon to carbon bond in erucic acid prevents the molecule from packing closely together. The lack of any double carbon-carbon bonds in behenic acid causes the molecule to be come polar and therefore packed more tightly. The larger number of carbon atoms in erucic acid prevents the molecule from packing tightly together. OH The smaller number of carbon atoms in behenic acid creates stronger covalent bonds between the carbon atoms allowing for them to pack more tightly together.
Consider the following tetrapeptide, written in a sequence according to normal convention, from left to right: Residue 1 is acidic; Residue 2 is proline (a large hydrophobic amino acid); Residue 3 is cysteine (an amino acid containing a -CH2SH R-group); Residue 4 is basic. Which of the following four general statements is TRUE regarding this tetrapeptide? This tetrapeptide probably is not part of an alpha-helix, since the large size of the proline would disrupt the consistency of the spiral shape. Residue 3 belongs to the amino acid category known as "basic." This tetrapeptide has the ability to form a disulfide linkage with an identical tetrapeptide. The acidic residue (Residue #1) is at the amino terminus of this tetrapeptide. 3 of these 4 responses are correct
