FINAL 04 - Analysis of Lipids in Egg Yolk Flashcards
Are heterogenous groups of compounds synthesized by living cells; generally soluble in non-polar organic solvents and insoluble in water
Lipids
Means not soluble in plasma
Hydrophobic
Means covered with proteins
Lipoproteins
Are carrying lipids in the body (Groups of lipids)
Lipoproteins
Meaning of VLDL (Examples of lipoproteins)
Very low-density lipoproteins
Meaning of HDL; carries cholesterol from vessels to liver where it is metabolized (Examples of lipoproteins)
High density lipoproteins
Meaning of LDL; deposits cholesterol to other parts of the body (Examples of lipoproteins)
Low density lipoproteins
Serves as energy storage, protection, insulation, and source of energy; composed of glycerol and fatty acids (Groups of lipids)
Triglycerides
Are membrane lipids; composed of glycerol + fatty acids + phosphoric acid + organic molecules (Groups of lipids)
Phospholipids/Phosphoglycerides
Refers to the parent compound of all phospholipids (Components of phospholipids)
Phospatidic acid
Also known as lecithin; is tested using the identification test of choline called Rosenheim test (Components of phospholipids)
Phosphatidyl choline
Also known as cephalin (Components of phospholipids)
Phosphatidyl ethanolamine
Also known as cardiolipin (Components of phospholipids)
Phosphatidyl glycerol
A component of cell membrane and myelin sheath; composed of ceramide + phosphoric acid + organic molecule (Groups of lipids)
Sphingolipids/Glycolipids/Glycosphingolipids
Monosaccharide found in sphingolipids
Cerebroside
Disaccharide found in sphingolipids
Globoside
Charged group found in sphingolipids
