Lipid- 2 Flashcards
What macronutrients goes through these stages of digestion:
1- fat emulsified by bile acids
2- hydrolysis of TG into MG and FFA
3- reform TG in small intestine
4- TG in phospholipids, cholesterol, proteins = chylomicrons
5- chylomicrons absorbed by lymph —> thoracic duct
6- thoracic duct —> jugular vein
Fat
What macronutrient absorption is when LDL returns to liver and is cleared from blood stream?
Fat
What type of TG is in palm, kernel, and coconut oil, and largely absorbed in portal vein?
Medium chain TG
What is the lipid problem when:
Accumulation of lymphatic fluid in pleural space
Chylothorax
What is the lipid problem when:
Pathologic dilation of intestinal lymph vessels
Lymphangiectasia
What is the endogenous lipid abnormalities:
Turbidity of sample caused by accumulation of lipoprotein particles
Lipemia
What is the lipid problem when:
Increase cholesterol in blood
Hypercholesterolemia
What is the lipid problem when:
Increased blood TGs
Hypertriglyceridemia
What is the most common reason for hyperlipidemia in a blood sample after it’s drawn and increasing chylomicrons causes it?
Post-prandial hypertriglyceridemia
What type of hyperlipidemia is diagnosed by increase in TG and cholesterol in blood in dogs and cats?
Primary hyperlipidemia
What is the most concentrated dietary energy source, and provides essential nutrients?
Fat
What is fat transported in the blood as?
Lipoproteins
What does fat provide and acts like a vehicle for?
Essential fatty acids
Vitamins
What is observed through lymphatics in the intestines?
Fat
What metabolism that can causes severe diseases?
Lipid
