Interpretation Introduction

Interpretation: It should be identified among the following option that is not an example of lipid.

Concept Introduction:

Proteins: Proteins are condensation polymers formed from amino acids. Proteins provide structural support, help organisms move, store and transport chemicals from one area to another.

Lipids: Lipids are the important type of compound found in organism.

They are the principle of components of the cell membrane and a repository of chemical energy in the form of fat.

In addition to the some of the chemical messenger called hormones are lipids.

Polar compound tends to be soluble in polar solvent such as water. But nonpolar compound are soluble in non-polar solvent but they tends not to be soluble in organic solvent.

Fluid – mosaic model:

A cell membrane is made up primarily of a phospholipid bilayer in which are embedded cholesterol, other lipids and proteins. Movements whining a layer occurs, but movement from one side of the bilayer to the other is rare.
