When a sample of purified phospholipids is mixed with water, spherical structures called liposomes form. Which of the following characteristics of phospholipids enable liposomes to form in water?
A) Liposome formation favors the interaction of electrostatic attractions between phospholipid head groups.
B) The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.
C) The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.
D) Liposome Thermodynamics favors liposome formation by causing water exclusion from the lumen.
E) The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar

B). The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.

C) The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.

E) The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar

Explanation:

A liposome is simply a tiny bubble also referred to as vesicle that is gotten from the same material as the one a cell membrane is made from. It should be noted that liposomes can be filled with drugs, and then used in the delivery of drugs for diseases such as cancer etc.

Phospholipids afford fluidity, permeability and stability to neural membranes. They're also vital for proper functioning of the receptors, integral membrane proteins, and the ion channels.

The characteristics of phospholipids that enable liposomes to form in water are:

• The edges of lipid bilayers sheets fold back on themselves, forming a hollow sphere which releases the ordered waters at the edges.

• The hydrophobic effect drives aggregation of phospholipids in an aqueous solution.

• The cross-sectionalarea of the headgroups and acyl chains in the phospholipids are similar

it's c. elements are placed in rows based on how may valencies electrons have.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
