Answer: Cardboard containers are best for protecting the riboflavin content of milk.
Riboflavin or vitamin B2 acts as a coenzyme in the metabolism of flavin mononucleotide and flavin adenine dinucleotide. The riboflavin is destroyed by irradiations and ultraviolet rays and therefore the milk is sold in opaque containers which are stable to heat. The tetra pack used now days is made up of cardboard and best suitable for using as a container to protect the riboflavin content of the milk.
A cell membrane has consists of phospholipids. They are lipids with a phosphate group such as (PO3/4). They are hydrophilic meaning that they allow water to pass through proteins well some at least- but it might be needed to move molecules throughnthe membrane as well. But basically it's just a composed bilayer of phospholipids with hydrophobic acid tails so that they could all meet with one another. The form complexes into function to describe or to identify the cells to anothers cells.
