1. Identify the following lipid-based structure and briefly describe (1-2 sentences) their basic characteristics.

a. 
- **Diagram Description**: A spherical assembly showing a hydrophobic bilayer, hydrophilic core, cholesterol, and phospholipids.
- **Explanation**: This is a liposome, a spherical vesicle with a phospholipid bilayer that surrounds an aqueous core, often used to deliver drugs due to their ability to encapsulate hydrophilic substances.

b. 
- **Diagram Description**: A micellar structure with hydrophilic heads and hydrophobic tails, forming a sphere in an aqueous solution.
- **Explanation**: This is a micelle, an aggregate of surfactant molecules dispersed in a liquid colloid, with hydrophilic heads facing outward and hydrophobic tails inward, aiding in the solubilization of hydrophobic substances.

c. 
- **Diagram Description**: A solid lipid nanoparticle with a surfactant layer, solid lipid core, and encapsulated therapeutic agents.
- **Explanation**: This is a solid lipid nanoparticle, a submicron colloidal carrier system composed of biodegradable lipids, used for controlled drug release and enhanced bioavailability of poorly soluble drugs.

d. 
- **Diagram Description**: A reverse micelle with hydrophilic heads inside and hydrophobic tails outside, in an organic solvent.
- **Explanation**: This is a reverse micelle, formed in non-polar solvents where the hydrophilic heads are oriented inward and hydrophobic tails outward, useful for solubilizing polar molecules in non-polar environments.

Step 1: About fats

All the images are lipid based structures. These are same woth respect to the fact that all of them are made up of lipids and different that the arrangement of lipids is different. Lipids are fat molecules are made up of fatty acids and glycerol.
