GENERAL HISTOLOGY

Detailed explanation-1: -Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.

Detailed explanation-2: -Phospholipids. Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane.

Detailed explanation-3: -There are three major classes of membrane lipid molecules-phospholipids, cholesterol, and glycolipids.

Detailed explanation-4: -Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides.

Detailed explanation-5: -The most important lipid component of membranes is fatty acids. A fatty acid is a mono-carboxylic acid with a long (normally 14–24 carbons), un-branched, hydrophobic tail which may be either saturated or unsaturated (usually 0–6 cis non-conjugated double bonds).
