Question

phospholipids
polar group
fatty acid \tails\
phosphate \head\ group
non - polar region
:: unsaturated groups only :: main component of cell membranes :: hydrophobic :: fatty acid \tails\
:: phosphate \head\ group :: composed of amino acids :: hydrophilic

Explanation:

• Phospholipids: Main component of cell membranes.
• Polar group: Phosphate "head" group, hydrophilic.
• Fatty acid "tails": Hydrophobic.
• Phosphate "head" group: Polar group, hydrophilic.
• Non - polar region: Fatty acid "tails", hydrophobic.

Answer:

• phospholipids: main component of cell membranes
• polar group: phosphate "head" group, hydrophilic
• fatty acid "tails": hydrophobic
• phosphate "head" group: polar group, hydrophilic
• non - polar region: fatty acid "tails", hydrophobic
