A fatty acid has one double covalent bond betweencarbon atoms.a. cholesterol c. phospholipid e. saturatedb. monounsaturated d. polyunsaturated
This type of noncovalent bond is responsible for clustering fatty acid tails of phospholipids in a micelle.
a. Disulfide bonds
b. Hydrogen bonds
c. Hydrophobic interactions
d. Ionic interactions
e. van der Waals interactions
One of the results of a fat being saturated is that the molecules interact stronger. This means that saturated fats are usually solid at room temperature while unsaturated fats are typically liquids. The interactions between triglycerides falls under which of the following types.

a. Covalent Bonds
b. van der Walls bonds
c. Hydrogen Bonds
d. Ionic Bonds
