8. Which of the lipoproteins is LEAST dense? 9. Which of the lipoproteins is MOST dense? 10. Which lipoprotein leaves the liver and delivers fat to muscle and fat tissue? 11. Which lipoprotein delivers cholesterol to our tissues? 12. When triglycerides undergo hydrolysis, they form glycerol and 3 fatty acids. How many fatty acid molecules can be transported in the blood by one albumin protein? 13. What is produced during ""starvation"" (or just a no carb diet)? What key organ can these molecules sustain from an energy standpoint? 14. Which form of cholesterol is considered the ""good"

The four lipoproteins that transport lipids throughout the body are globular structures composed of a lipid center surrounded by a coat of protein. Each lipoprotein has a different density, determined by the ratio of protein to lipid; the more protein each lipoprotein contains, the higher its density. The density determines how the lipoprotein functions. Match the below mention lipoproteins with the given Lipids. a. This lipoprotein contains the most cholesterol of all lipoprotein and about 25% protein. b. This lipoprotein contains a mixture of lipids, most of which is 60% triglycerides and about 10% protein. c. This lipoprotein contains the most triglycerides and the least protein. d. This lipoprotein contains 50% of its composition as protein and other 50% is composed of triglycerides, cholesterol and phospholipids. Lipids: 1. Chylomicron 2. VLDL 3. LDL 4. HDL 5. Micelle

The following are components of the lipid profile. Explain how each of these substances is influenced by the Ketogenic diet. • Triglycerides • Cholesterol • High-Density Lipoprotein (HDL) • Low-Density Lipoprotein (LDL) 5. Give three other long-term effects of ketosis in the body? Explain 6. How are fatty acids related to the Ketogenic diet? Explain. (4 pts)

Lipoproteins are relatively large, spherical clumps of protein and lipid molecules that circulate in the blood of mammals. They are like suitcases that move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to another in the body. Given what you know about the insolubility of lipids in water, which of the three kinds of lipids would you predict to be on the outside of a lipoprotein clump, bathed in the fluid portion of blood?
