Relatively large biological molecule that mostly does not dissolve in water.Lipids include fats, oils, cholesterol, a number of steroid hormones, the major constituents of cell membranes, etc.Lipids are predominantly hydrophobic substances, though can have hydrophilic portions as well. An example of the latter are lipids associated with membranes, that is, lipid bilayers, include phospholipids and the molecule, cholesterol.Unlike proteins, carbohydrates, and nucleic acids, lipids are less homogenous in terms of their structures. In particular, lipids do not have a consistent subunit from which they are polymerized but instead are categorized together as a group based upon their relative inability to dissolve in aqueous solutions. That is, they are oil-like in the generic sense of that term. The video placed a whole new spin on the age of rap and showed that is just not for young persons.Furthermore, while being enjoyable it also teaches one about lipids in a fun interactive session.
