the imbalance of lipids such as cholesterol
disorder of lipid and lipidproteinmetabolism
imbalance of LDL-C (low-density lipoprotein cholesterol), tryglycerides, and HDL (high-desity lipoprotein)
What are common forms of dyslipidemia?
Elevated triglycerides
Elevated LDL
Elevated cholesterol
Reduced HDL
What are Lipids? Name the lipid classes
Organic Molecules that are soluble in organic solvents but not water
Contain fatty acids or their derivates
Neutral Lipids:
Triglycerides
Diglycerides
Monoglycerides
Free Fatty Acidds
Phospolipids
Cholines
Ethanolamines
Serines
Sterols
Cholesterols
Cholesterols Esters
Waxes
Ceramides
VLC
Transfats disrupt normal membrane structure & cause aggregation of lipis, formin plaques or blockades over time the veins
Transfats are more thermodynamic stable in higher trempreture
omega 3 acids have from the end counting on th C3 position a unsteady bond
can not be synthesised by humans
necessary for the growth and human brain function
anti-inflammatory properties
1 g/ day needed
Triglycerides?
main compound of stored human body fat
tree fatty acids and glycerol
Two major enzyme classes control TG level:
Lipadases -> degradation
Diaclglycerol acetyltransferades -> sytehesis
Testings:
<150 mg/dL
< 1.70 mmol/L
Cholesterol
30% of the human membrane
maintains membran fluidity & itrity in different tempretures
50% diet 50 % synthesised
<5.2 mmol/l low risk
6.2 high risk
What are lipoproteins?
Biochemical assembly of lipids and proteins for efficient transporting fats in the body
Transport occurs trough the lympatic & circulatory system
Lipids: phospholipids, triglycerides & cholesterols formin membranes
Proteins: Apoproteins are embedded in these membranes
Apolipoproteins stabilize and determine
Classification of Lipoproteins
Apo-Lipis are detergents to pack lipids and to solubilise for transport
apo-lP have different receptor ligands, and different tissues
Indicator for health issues
VLDL>IDL>LDL>HDL
dencity decreasing & volume increasing
VLDL- 50% triglycerides & cholesterols, 30% cholesterol content
LDL - 65 % cholesterol (20% less volume than VLDL)
Hdl (high protein) good fat
Major Phospholipids + Cholesterol Depot
Treatments for dyslipidemia
Early:
diet control, sports, weight controll
Omega 3 and niancin supplementation
Indikactor: HIGH LDL- cholesterol
bile acid binders
change cholersterol into cholic acid
Cholesterol absorption inhibitors
Decreases cholesterol absorption in the intestine
increasing of cholesterol extraction
Indicator: High VLDL-cholesterol, high TG
Drug: Strains (atorovastin, flucvastin) most common method
Blocks cholesterol biosynthesises
increasing removal of cholesterols from the body
blocking HMG-Coa reductase
