Using the ultrasonication and agitation method of liposome preparation, what concentration of lipid is necessary to prepare lipo
Galina-37 [17]

The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

<h3>What are liposomes?</h3>

Liposomes are vesicles which are made up of a lipid bilayer membrane.

Liposomes are important as delivery vehicles for substances such as drugs.

Ultrasonication is a method of liposomes preparation.

Solution of liposomes is dependent on the size.

The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.

Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

You have a cup of vegetable oil and a vial full of normal phospholipids. What would you predict would happen if you dropped the
Jobisdone [24]

The vegetable oil is made up of chains of long fatty acids. These long chains of fatty acids are non-polar in nature, i.e, they do not interact through ionic forces rather by covalent forces. The phospholipids are also long chain fatty acids with an ionic head. The mixing of the vial of phospholipid in vegatable oil will lead to the formation of a micelle where the lipophilic ends of the phospholipid will be on the outside and the lipophobic end will be towards the centre of the micelle.
