Soaps And Phospholipids Flashcards
Phospholipids hydrophobic
Hydrophobic tails similar to neutral fats with two fatty acids attached to glycerol
What type of character do phospholipids have?
Amphiphilic character
Hydrophilic phospholipids
Hydrophilic head differs from neutral fat with the third fatty acid replaced with a phosphate group attached to other functional groups
What do phospholipids also make up?
Phospholipids also make up the cell membranes of the cell
How soaps work
Soap molecules break up and surround oil droplets (I.e emulsifying it)
What is used in the human body?
In the human body bile is used to emulsify fat in your diet
