In what disease process would you see increased lipids, essential fatty acids, and vitamins A D E K in feces
Steatorrhea
Treatment of Steatorrhea would be>
supplementation of short less than 6 carbon and medium 6-12 chain fatty acids
those type of FA don’t require micelle formation to absorb
NASH is
non alcoholic Steatorrhea hepatitis
fat build up killing liver
Ketoacidosis results when ?
the rate of formation of ketone bodies is higher than the rate of use
Ketoacidosis occurs in DM type 1 because excessive formation of ketone bodies forces___ ___ into ketone body pathway.
acetyl CoA
In ketoacidosis the ketone body has a low pH causing what?
loses hydrogen to plasma, lowers physiological PH, results in metabolic acidosis
Dehydration results from ketoacidosis because
excretion of excretion of glucose and ketone bodies in the urine.
water follows the ketone bodies and sugar

6
hyperammonemia
what would the cause of hyperammonemia be?
ammonia formation exceeds urea cycle capacity due to declining liver function related to hepatic disease that results in deficient urea cycle enzymes
high homocysteine levels from methionine metabolism would result in
neural tube defect
elevated homocysteine levels from methionine metabolism is related to atherosclerosis why?
foam cells
elevated homocysteine promotes oxidative damage, inflammation, and endothelial damage
what supplement would you give to lower homocysteine?
folate
