Capillary action is defined as the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur. In fact, it often acts in opposition to gravity. Capillary action is sometimes called capillary motion, capillarity, or wicking. | ||||
| ح_ | Capilary action | ||
|---|---|---|---|
The process that makes a nonpolar organic move up of the plates on the process separation of lipid | |||
| ا_ | capillary action | ||
|---|---|---|---|
Capillary action :- is the process of a liquid flowing in a narrow space without the assistance of , or even in opposition to ,any external forces like gravity . the effect can be seen in some non porous materials such as sand and liquefied carbon fiber,or in a biological cell.it occurs because of intermolecular forces between the liquid and surrounding solid surfaces. | |||
| ج_ | Chelating | ||
|---|---|---|---|
A chelating agent is a chemical compound that reacts with metal ions to form stable, water-soluble metal complexes. The agent rearranges the metal's chemical composition and improves the metal's general stability and likelihood to bond with other substances. Chelating agents are used in several applications, including:

| ا_ | embedded | ||
|---|---|---|---|
exists in tow layars (bilayar) . like integral membrane proteins are " embedded" in the lipid bilayar . | |||

| ض_ | Fatty Acids | ||
|---|---|---|---|
Fatty acids are the basic building blocks of fats in our bodies and in food. They are components of all membrane lipids except for sterols. The body breaks down fats into fatty acids and their hydrocarbon tails provide a diffusion of polar solutes. The sizes of fatty acids range between 12-20 carbon atoms, and there are two types of fatty acids: saturated fatty acid And unsaturated fatty acid | |||
| م_ | Fluidity buffer . | ||
|---|---|---|---|
Cholesterol is found in animal cell membrane.it makes the membrane more fluid and stable .This is through what is nkown fluidity buffer,This means cholesterol acts as abidirectional regulator of membrane fluidity because at high temperatures it stabilizes the membrane and raises its melting point whereas at low temperatures if intercalates between the phospholipids and prevents them from clustering together and stiffening . | |||
Fluorescence antibody (FA) | |||
|---|---|---|---|
It is a fluorescent antibody technique, its abbreviation (FA), involves the use of cells or antibodies, where it marks its fixed region with a fluorescent marker known as a fluorophore, and this technique is often classified as direct or indirect | |||

| ح_ | glycocalyx | ||
|---|---|---|---|
The carbohydrate groups of plasma membrane glycoproteins and glycolipids form a surface layer found in animal cells | |||
