Explain the chemical nature of storage fats in the body. How are they stored (chemically), where are they stored (biologically). Explain the diversity in this group of molecules. Give a short historical perspective on saponification reaction and how it was used, starting supplies, etc.

Why are the fatty acids referred to as salts? Which takes more NaOH for complete saponification, 27 grams of olive oil, butter or lard? Since the same amount of NaOH, which soap should be more basic? Why?
Discuss why fatty acid salts can act as soaps.
Discuss the disadvantages of natural soaps.

Q. Free fatty acids (FFA) were measured in fasting blood sample of 13 non-insulin-dependent diabetic men and 10 non-diabetic men. The results (in mmoI/L) were:

Diabetic:

430 340 560 390 430 385 345 370 317 311 687 323 618

Non-diabetic:

445 265 493 265 410 274 296 219 286 250

a) Determine if the FFA is different for diabetic men and non-diabetic men

b) Write a brief summary of what the result show

Thermogenesis is an important function of Brown Adipose Tissue (BAT). Which of the following statements about BAT is FALSE?

I. Unlike other tissues, BAT does not degrade free fatty acids via β-oxidation.

II. BAT has smaller lipid droplets and more mitochondria than White Adipose Tissue.

III. In BAT, UCP1 forms a channel in the inner mitochondrial membrane that dissipates the energy in the H⁺ gradient as heat.
