3.1.1 Types of surfactant and their structure Surfactants are usually organic compounds that are amphiphilic, meaning they contain both hydrophobic groups (tails) and hydrophilic groups (heads). Therefore, a surfactant molecule contains either a water insoluble or oil soluble component and a water sol...
Can a molecule have both hydrophobic and hydrophilic regions? Yes, such as in phospholipids which have a hydrophilic head and hydrophobic tails. 7 What characterizes hydrophilic molecules? Hydrophilic molecules attract and readily interact with water. 6 Why are some proteins both hydrophilic and hydroph...
ultra-long chain cis-15-tetracosenoic acid (UC24:1) bio-based zwitterionic surfactants with different hydrophilic head groups (TAPAA, TAPAHPS, and TAPABS) was developed from the non-edible fatty acid (Z)− 15-tetracosenoic acid (UC24:1) by a simple and productive method (Scheme 1)....
Select the correct answer. Cell membranes are composed of phospholipids. These unusual molecules have an area of the molecule that is hydrophobic (the 'tails') and an area of the molecule that is hydrophilic (the 'head'). Which would you predict about a p ...
The phospholipids of plasma membranes have A) a hydrophobic head and a hydrophilic tail. B) a hydrophobic head and a hydrophobic tail. C) a hydrophobic head and two hydrophobic tails. D) a hydrophilic head and two hydrophobic tails. E) a hydrophilic head A phospholipids bilayer that surround...
The cell membrane is a phospholipid bilayer - this means that there are two rows of phospholipid molecules with the fatty acid tails in the middle making it nonpolar. The phosphate based heads are on the inner and outer sides of the membrane where polar water molecules can interact with the ...
