Log in here for access. Sebum, an oily material secreted by glands in the skin, has a physiological role, but abnormally high secretion of sebum can be associated with acne. In fact, it likes to store energy as fat because lipids can store more energy, or calories, per gram than carbohydrates. One key process triggered by eating is called lipogenesis, which is when our liver begins converting food into fats for storage across the body. Treatment usually begins with medications and chemotherapy , Although in many cases a blood transfusion or a bone marrow transplant is necessary. D) Lipoproteins. Lipoproteins, carrying mostly cholesterol and phospholipids from the liver to the peripheral tissues are called? Chapter 7 review Nutritional Sciences - Chapter 7. E. The process proceeds with the help of fatty acid synthase, which is a complex of enzymes that catalyze the conversion of acetyl-CoA to fatty acid. Both AFLD and NAFLD generally begin as hepatic steatosis, and if the cause persists, this steatosis invariably progresses to steatohepatitis, cirrhosis, and liver cancer (2, 6, 10, 15, 21, 25).Hepatic steatosis represents an excess accumulation of fat (triglycerides) in hepatic parenchymal cells (hepatocytes) of the liver, and it occurs in etiologically diverse conditions. Large areas of scar tissue start to interfere with blood flow to functioning liver cells, causing them to die and resulting in the formation of more scar tissue. It is kind of like glucose is a car looking for a parking place. c. fatty acids. Alcohol-induced fatty liver generally begins as hepatic steatosis, and if the cause persists, this invariably progresses to steatohepatitis and cirrhosis. glucose.
