(a)
Interpretation:
The site of process of fatty acid synthesis and degradation must be compared.
Concept introduction:
The fatty acids are degraded in a sequential manner, that is two carbon units at the carboxyl end of the molecule are removed in each step. The process of beta-oxidation of fatty acids degrades the fatty acids. The process of fatty acid synthesis is a stepwise process, which occurs by the addition of two-carbon units. These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.
(b)
Interpretation:
The acyl carrier of fatty acid synthesis and degradation must be compared.
Concept introduction:
The fatty acids are degraded in a sequential manner, that is two carbon units at the carboxyl end of the molecule are removed in each step. The process of beta-oxidation of fatty acids degrades the fatty acids. The process of fatty acid synthesis is a stepwise process, which occurs by the addition of two-carbon units. These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.
(c)
Interpretation:
The reductants and oxidants of fatty acid synthesis and degradation must be compared.
Concept introduction:
The fatty acids are degraded in a sequential manner, that is, two carbon units at the carboxyl end of the molecule are removed in each step. The process of beta-oxidation of fatty acids degrades the fatty acids. The process of fatty acid synthesis is a stepwise process, which occurs by the addition of two-carbon units. These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.
(d)
Interpretation:
The stereochemistry of intermediates of fatty acid synthesis and degradation must be compared.
Concept introduction:
The fatty acids are degraded in a sequential manner, that is, two carbon units at the carboxyl end of the molecule are removed in each step. The process of beta-oxidation of fatty acids degrades the fatty acids. The process of fatty acid synthesis is a stepwise process, which occurs by the addition of two-carbon units. These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.
(e)
Interpretation:
The direction of fatty acid synthesis and degradation must be compared.
Concept introduction:
The fatty acids are degraded in a sequential manner, that is, two carbon units at the carboxyl end of the molecule are removed in each step. The process of beta-oxidation of fatty acids degrades the fatty acids. The process of fatty acid synthesis is a stepwise process, which occurs by the addition of two-carbon units. These carbon units are provided by the acetyl-CoA, derived from glucose oxidation.
(f)
Interpretation:
The organization of the enzyme system of fatty acid synthesis and degradation must be compared.

- 9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes.
