Detailed explanation-1: -The lipid tails face the interior of a biological membrane (Figure 1.3. 1). Phospholipids, glycerolipids, and sphingolipids contain one or more (usually two) fatty acid chains as hydrophobic tails. A portion of the sphingoid base also makes up part of the hydrophobic tail of a sphingolipid.
Detailed explanation-2: -In the cell membrane the phospholipids are arranged so that the heads face the aqueous internal environment and aqueous external environment. The tails are sandwiched in between the heads where they are protected from interactions with water.
Detailed explanation-3: -Hence, the correct answer is ‘The non-polar or hydrophobic hydrocarbons tails of lipid, being on inner side ensure their protection from the aqueous environment.
