BIOMOLECULES AND ENZYMES

Detailed explanation-1: -In many multipass transmembrane proteins, some of the transmembrane helices contain both hydrophobic and hydrophilic amino acid side chains. The hydrophobic side chains lie on one side of the helix, exposed to the lipid of the membrane.

Detailed explanation-2: -The molecules or proteins are considered hydrophilic. These molecules are also referred to as water-loving molecules.

Detailed explanation-3: -A phospholipid is an amphipathic molecule which means it has both a hydrophobic and a hydrophilic component.

Detailed explanation-4: -Proteins are also part of the cell membrane. Like phospholipids, some proteins also have hydrophilic and hydrophobic regions.

Detailed explanation-5: -A phospholipid consists of a hydrophilic (water-loving) head and hydrophobic (water-fearing) tail. In water, phospholipids spontaneously form a double layer called a lipid bilayer, in which the hydrophobic tails of phospholipid molecules are sandwiched between two layers of hydrophilic heads.
