WebApr 30, 2024 · A phospholipid consists of a hydrophilic (water-loving) head and hydrophobic (water-fearing) tail. In water, phospholipids spontaneously form a double layer called a lipid bilayer, in which the hydrophobic tails of phospholipid molecules are sandwiched between two layers of hydrophilic heads. WebApr 9, 2024 · The head can form hydrogen bonds, but the tail cannot. A molecule with this arrangement of a positively or negatively charged area and an uncharged, or non-polar, area is referred to as amphiphilic or “dual-loving.” Figure \(\PageIndex{2}\): This phospholipid molecule is composed of a hydrophilic head and two hydrophobic tails.

"WebThe phospholipid bilayer acts as a barrier allowing the smaller molecules such as O 2 and glycerol in, but keeping larger molecules such as amino acids and ions out. The bilayer can be broken down by detergents. Aside from phosphoglycerides, another class of lipids commonly found within the body are sphingolipids.
