“Saturated” fats versus “unsaturated” fats<br />
he fatty acid is said to be unsaturated because it has less<br />
han the maximum number of hydrogens at the location of<br />
he double bond.<br />
Fatty acids are saturated because they are bonded to<br />
the maximum number of hydrogen atoms.<br />
Saturated fats<br />
Stearic acid<br />
- Solid at room temperature<br />
Saturated fat and fatty acid.<br />
Unsaturated fats<br />
- Usually liquid at room temperature<br />
Unsaturated fat and fatty acid.<br />
Phospholipids<br />
•In a phospholipid, two fatty acids and a phosphate group<br />
are attached to glycerol<br />

When phospholipids are added to water, they selfassemble<br />
into a bilayer, with the hydrophobic tails<br />
pointing toward the interior<br />

The structure of phospholipids results in a bilayer<br />
arrangement found in cell membranes<br />
