(a)
Interpretation:
The precursor of the given unsaturated fatty acid must be determined.
Concept introduction:
Double bond/bonds can be introduced in the newly synthesized fatty acid by both eukaryotes and prokaryotes. In eukaryotes, Cyt b5, oxygen-dependent desaturase, and NADH-cytochrome b5 reductase are responsible for the unsaturation of fatty acids. The desaturase enzyme used here contains a non-heme iron atom and this enzyme is an integral membrane protein.

The precursor of the given unsaturated fatty acid must be determined.

- . Explain what is meant by the term, “high energy compound”. Name a thioester molecule that is commonly found in biochemical reactions. Explain why thioesters are “high energy” compounds. Describe the molecular structure of cellulose. How does this structure explain why cellulose forms strong fibers? Explain why digestion of cellulose takes a long time even when catalyzed by an enzyme. The enzyme phosphofructokinase transfers a phosphate from ATP to the hydroxyl group a C1 of fructose. Similar to fructose, water also has a hydroxyl group and the concentration of water is much higher than that of fructose. Explain why the phosphate is transferred to fructose and not to water.arrow_forwardI. Buffer Preparation A researcher in Biochemistry is isolating α-glucosidase enzyme from malted wheat flour. The protocol requires the use of 2.00L of 0.225 M of lactate buffer with pH of 4.25. How will he/she prepare this buffer from 2.00 M lactic acid solution and solid sodium lactate (NaC3H5O3) The Ka of lactic acid is 1.38 x 10-4.

The formation of a hydrogen bonding dimer of N-methylacetamide has been studied as a model for hydrogen bonding in proteins. The thermodynamic parameters (at 298 K) measured for this process in water are shown below. 2 H3C-N H N-methylacetamide CH3 H3C HN CH3 HN CH3 AG° = 3.1 kcal mol-1 AH° 0.0 kcal mol-1 AS° -10 cal mol-1 K-1 H3C N-methylacetamide hydrogen-bonded dimer a) Provide a molecular level reasoning for the value of AH° and sign of ASO for this process. b) The conclusion below may be drawn from these data. Explain how his conclusion is reached. Hydrogen bonds are unlikely to be a strong stabilizing factor for a protein folding in water. c) Do you agree with this conclusion? What might be a limitation of this model for describing protein folding? d) It is well known that hydrogen bonds are prevalent in folded protein structures, so they appear to be important. So, if this conclusion is correct, what is an alternative possible role of hydrogen bonds in protein folding?arrow_forward
