Lipids Flashcards
Exam 1
What method for lipoprotein electrophoresis depends on charge and molecular size
Polyacrylamide gel
Chylomicrons
A lipoprotein produced in the intestinal mucosa, primary function is to carry dietary lipids to the liver, remains at the origin during lipoprotein electrophoresis
The lipoprotein that contains the greatest amount of protein is called
HDL
Several enzymatic triglyceride methods measure the production or consumption of
Nadh
The most likely cause for serum or plasma to appear milky is the presence of
Chylomicrons
In the car on Metric determination of cholesterol using the enzyme cholesterol oxidase, the agent that oxidizes the colorless organic compound 4 aminoantipyrine to a pink complex is
Hydrogen peroxide
Which lipoprotein is the major carrier of cholesterol to peripheral tissues
LDL
What is the presumed effect in most cases of familial type to a hyper lipoprotein anemia
Defective receptors for LDL
Hyperchylomicronemia type 1 is childhood has been associated with which of the following deficiencies
A deficiency of a Apo C II
HDL quantitation is used in correlating the risk of
Coronary heart disease
Triglycerides are transported in plasma mostly in the form of large triglyceride which particles called
Chylomicrons
The lipoprotein that contains the greatest amount of protein is called
HDL
Which lipoprotein is the major carrier of cholesterol to peripheral tissue
LDL
Cholesterol functions in the
Steroid hormone precursor, membrane structure, bile acid precursor
What is the major fatty acid Ester fide to cholesterol in normal serum
Linoleic
The primary function is to carry dietary exogenesis lipids to the liver, remains at the origin during lipoprotein electrophoresis, lipoprotein is produced in the intestinal mucosa
Chylomicrons
Premature arterial sclerosis can occur when what is elevated
LDL
High levels of which lipoprotein class are associated with decreased risk of arthro sclerosis
HDL
Dietary lipids are first broken down and packaged into
Micelles which are then absorbed by the intestines
What percentage of total cholesterol is typically in LDL, HDL, VLDL
65% LDL, 25% HDL, 10% VLDL
A disease of the arteries that Supply blood and oxygen to the heart that causes decreased blood flow to the heart muscle
Coronary artery disease
Removes excess cholesterol and takes it from tissues back to the liver where cholesterol is converted to bile salts and excreted
HDL
Routes cholesterol through the body from liver to peripheral tissues
LDL
Most cells especially the liver and adipose cells can synthesize triglycerides
Endogenous
