Marine animals, which are hypo-osmotic, actively exclude salts. Some marine animals increase the concentrations of solutes, such as urea and amino acids, in their body fluids to match the osmotic potential of seawater and thus reduce the movement of water out of their bodies

                                                               β-turns

Most common turns, also termed as ẞ-bends, tight turns, reverse turns, generally connects

β-sheets.

The conformation of i+1 and i+2 are crucial and on the basis of this, they are classified

Consists of 4 amino acids, generally termed as i, i + 1 , i + 2 and i + 3

H-bond is seen between i and i+3 (First and Fourth residue)

Class II, but not class I, presentation is inhibited by treatment of the cells with an agent that blocks endocytic processing within the cell (chloroquine).
