Cell membrane Flashcards
Phospholipid
A lipid made of glycerol, two fatty acid tails and a phosphate-linked head group
Amphipathic
Having both hydrophilic and hydrophobic parts
Glycolipid
lipid with a carbohydrate attached
Cholesterol
A lipid composed of four used carbon rings
Glycoprotein
protein with a carbohydrate attached
Micelle
Phospholipid unit surrounding emulsified fat absorbed by enterocytes
Liposome
A phospholipid bilayer that forms into an energetically favorable sphere to protect its hydrophobic regions
Integral membrane proteins
proteins that are anchored to the hydrophobic core of the phospholipid bilayer by at least one hydrophobic region
Transmembrane proteins
Integral proteins that span the entire membrane
Peripheral membrane protein
Proteins that are attached to either integral proteins or to phospholipids
Semipermeable membrane
A membrane that allows only certain substances to enter or leave a cell
