Lipids are soluble in? | Organic solvents |
What is the best method to demonstrate lipids | Frozen |
What are the types of unconjugated lipids | fatty acid, cholesterol |
What are the types of conjugated lipids? | ester lipids, phospholipids |
Name the conjugated lipids which are hydrophobic | Cholesterol esters, mono ditriglycerides, waxes |
Define hydrophilic | Likes water |
What lipids are hydrophilic | phospholipids, acidic lycolipids, neutral glycolipids |
Lipids in crystalline form are? | Isotropic and birefringent |
Why isnt Primary Flourescence used as a diagnostic tool for lipids | Because only certain lipids procduce 1 fluorescence |
Melting points, molecular weight of dye, and solubility of dye affects what? | The stainability of lipids with oil soluble dyes |
Hot chloroform does what? | Removes all lipids |
What solvents do not dissolve out lipids | isopropanol and propylene glycol |
Why must you use precaution when using aqueous mountants for coverslipping | If you press on coverslip too hard to remove air bubbles, it may dislodge fat |
What type of mounting media should be used with fat stains | synthetic resin |
Phosphate 3R & 3.4 Benzpyrene are? | two secondary flourescent methods used to detect lipids in formalin fixed frozen sections |
Permanent secondary flourescent method | Phosphate 3R |
