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.

Yanka [14]

Answer;

Carbon

Explanation;

-The large diversity of shapes of biological molecules is possible because of the extensive presence of carbon  in the molecules.

-The major classes of biological molecules that are important for all living things are carbohydrates, lipids, proteins, and nucleic acids. These molecules differ in structure and function, in part, because of different functional groups.

All organic molecules contain carbon atoms. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.

-Carbon qualifies as the foundation element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
