1.) Why is derivatization of fatty acids (esterification to methyl esters) necessary for GC analysis?2.) What is the purpose of boron trifluoride in this reaction? 3.) How would you isolate the free fatty acids from their triglycerides? Describe both the chemical reaction and the extraction procedure.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the answers would be

the first one and the second one

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
