7. On a density basis, there are three general classes of blood serum lipoproteins. One of thesecorrelates inversely with heart disease risk and is referred to as 'good cholesterol'. This socalled good cholesterol is actuallylow density lipoproteins, or LDLhigh density lipoproteins, or HDLvery low density lipoproteins, or VLDLchylomicron

Lipids are an important part of our daily diet. They are essential for the nourishment of the cells,…

2. The patient of 48 years old has survived a heart attack. The laboratory test of his serum blood were: total cholesterol 440 mg/dl (reference range is 40 mg/dl), calculated LDL cholesterol 340 mg/dl (reference range is <100 mg/dl), triacylglycerol 160 mg/dl (reference range is <150 mg/dl). Explain the results of the laboratory tests and suggest the possible causes of the patient's disease. For the answer: a) draw the scheme of the cholesterol synthesis; b) draw the formula for the LDL cholesterol calculation; c) explain the functions of LDL and HDL in cholesterol transport using the schemes and the results of the laboratory tests; d) name the most possible cause of the patient's decease.
9. An acute myocardial infarction, a thrombus of a coronary artery and ischemia results in necrosis. Patients complain of chest and epigastric pain radiating to the arms, shoulders, neck and associated with sweating, nausca and shortness of breath. Which serum enzyme activity measurement is used in clinic for differential diagnosis (from angina pectoris, acute pancreatitis, perforated stomach ulcer, etc.)? For the answer: a) enumerate transaminases which are measured in serum enzyme diagnostics. Write down reactions catalyzed by these enzymes; b) specify the coenzyme of these enzymes; c) explain the importance of these reactions in amino acid metabolism; d) point out other enzymes and proteins measured in serum enzyme diagnostics in myocardial infarction.
3) True or False Low density lipoproteins (LDLs) carry excess cholesterol from tissues to the liver.
Given that the normal range for serum protein is about 7 g/100ml and albumin is about 4 g/100ml, what clinical conclusions can you draw from the following samples A-C? If samples are not normal, what protein fraction is increased/decreased and with what disease is this protein pattern likely to be associated? Sample A: total protein = 14 g/100mlalbumin= 8 g/100 ml Sample B:total protein = 5.8 g/100ml albumin = 4 g/100 ml Sample C:total protein = 3.5 g/100mlalbumin = 2g/100 ml
A cholesterol screening has reported Toms blood serum contains 50mg/dal HDL and 180 mg/dal LDL and a total cholesterol of 255. What is the LDL/HDL ratio? Is this value considered in the healthy range?
14. Thirty minutes after eating Thanksgiving dinner, indicate the changes (if any) you'd expect to see in each of the following. You must briefly explain each answer.

Density lipoprotein increase the risk of atherosclerosis by forming fatty plaques in the walls of blood vessels.
Identify ALL of the following which are TRUE regarding cholesterol and disease: if an artery leading to the heart is blocked, a heart attack could result O Artery inflammation can increase the risk of clots and thromboses; this could lead to arterial blockage (reduced blood flow in an artery) blood vessel inflammation can become self-perpetuating; where inflammation occurs, it becomes more likely that inflammation will continue, especially when blood LDL are high and HDL are low An arterial plaque can increase the chance of developing hypertension exercise has no effect on blood cholesterol dietary artificial trans fats seem to increase LDL and decrease HDL more than both dietary saturated fats and dietary cholesterol in most people (that is, trans fats are worse than sat fats and cholesterol) if a product lists "partially hydrogenated" oil as an ingredient, it contains some trans fat even if it is less than .5 g per serving. hypertension can put extra strain on the heart and increase…
4. A 50-year-old diabetic comes to the laboratory to have rou- tine bloodwork drawn. His physician orders basic metabolic panel and a lipid profile. After the blood clots, the techni- cian spins down the specimen to find that the serum looks like milk. The test results are as follows: Na: 140 mEq/L K: 4.0 mEq/L Cl: 101 mEq/L CO2: 28 mg/dL Glucose: 455 mg/dL BUN: 24 mg/dL Creatinine: 1.1 mg/dL Phosphate: 3.7 mg/dL Calcium: 8.8 mg/dL ALP: 250 IU/L AST: 35 IU/L ALT: 29 IU/L Cholesterol: 500 mg/dL Triglycerides: 1200 mg/dL HDL: 35 mg/dL LDL: 160 mg/dL What causes the diabetic's serum to look like milk? What lipid test results do you expect to be elevated? How would this specimen fit into Fredrickson's classification scheme?
One of the following does not contribute to calcium- oxalate stones a. sodium-rich diet O b. calcium-rich diet O c. acidic-ash diet o d. dehydration

C) |l- Potassium levels falsely increase in values when blood specimen is not processed or centrifuged within 2 hours collection. III- Normally, potassium levels are higher in plasma than in cells.
