20
Q

Cause of fatty liver

A

Accumulation of triglycerides and other fats in the liver cell

21
Q

Conversion of carbs to fats

22
Q

Increase in fatty liver

A

Lipogenesis
Fatty acids
NADH
Glyceraldehyde 3 phosphate

23
Q

Decrease in fatty liver

A

NAD
Dehydrogenase
Catabolism

24
inhibited by the low NAD+/NADH ratio
Dehydrogenase
25
Potential pathophysiologic mechanisms for fatty liver include the following:
* Decreased mitochondrial fatty acid beta-oxidation * Increased endogenous fatty acid synthesis or enhanced delivery of fatty acids to the liver * Deficient incorporation or export of triglycerides as very low-density lipoprotein (VLDL)
26
normal circumstances:reduction of NAD (NAD to NADH) is finely regulated by the
Krebs cycle
27
excess production of superoxide radicals via the interaction of CYP2E1 with
Cytochrome reductase
28
Elevated levels of oxygen radicals can generate a state of oxidative stress, which through various mechanisms leads to
Cell damage
29
Oxygen radicals also can interact with fat molecules (lipids) in the cell in a process known as
Lipid peroxidation
