Overview of lipids, covering fats and oils, saturated and unsaturated fats, triglycerides (triacylglycerols), phospholipids, and steroids.

And we're gonna study that thoroughly as we go more into biology. So hopefully this gives you more appreciation of what a lipid is and the different types of lipids.

Lipids, commonly associated with fats, are a group of biomolecules with low water solubility. Lipids are essential for storing energy, transmitting signals, and creating cellular membranes.

Lipids tend to be hydrophobic, nonpolar, and made up mostly of hydrocarbon chains, though there are some variations on this, which we'll explore below. The different varieties of lipids have different …

The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.

Just as you can be thought of as an assortment of atoms or a walking, talking bag of water, you can also be viewed as a collection of four major types of large biological molecules: carbohydrates (such as …
