Phospholipids: Are composed of glycerol (hydrophilic) and two fatty acid tails that are ____. These are the primary constituent of ____ ____. A molecule like this, with a hydrophilic end and a hydrophobic end is called ____. Phospholipids spontaneously arrange themselves into a ____ ____ with the tails oriented to the ____ and the heads oriented to the ____. This arrangement facilitates one of the key roles of cell membranes; ____ of cell contents. The fatty acid tails can be made of ____ fats or ____ fats, and in organisms that are adapted to environments with significant temperature differences between summer and winter, these can change. This helps maintain membrane ____. Membranes have to be ____ in order for transport across the membrane to occur.

Which of the following statements is true of phospholipids and triglycerides: Triglycerides are composed of three fatty acids bonded to glycerol backbone. Phospholipids are phosphate head that is bonded directly to two fatty acids. Triglycerides are always associated with cell membranes; they provide flexibility. Phospholipids are composed of a phosphate group bonded to glycerol backbone and two random side groups. Phospholipids and triglycerides are not the same molecules.

Phospholipids are similar to triglycerides except that a phosphate group replaces one of the fatty acids. The phosphate group is a polar molecule. Polar molecules are hydrophilic and interact with water. Phosphate Group 7) Draw the structure of lecithin. Label the glycerol, phosphodiester linkage, alcohol, and fatty acid parts.
