Brief Introduction

Salicin is a naturally occurring compound found in the bark of several species of trees, primarily North American in origin, that are from the willow, poplar, and aspen families. White willow, from whose Latin name, Salix alba, the term salicin is derived, is the most well known source of this compound, but it is found in a number of other trees, shrubs, and herbaceous plants as well being synthesized commercially. It is a member of the glucoside family of chemicals and is used as an analgesic and antipyretic. Salicin is used as a precursor for the synthesis of salicylic acid and acetylsalicylic acid, commonly known as aspirin.

A colorless, crystalline solid in its pure form, salicin has the chemical formula C13H18O7. Part of its chemical structure is equivalent to the sugar glucose, meaning it is classified as a glucoside. It is soluble, but not strongly so, in water and alcolhol. Salicin has a bitter taste and is a natural analgesic and antipyretic, or fever reducer. In large quantities, it can be toxic, and overdoses may lead to liver and kidney damage. In its raw form, it may be mildly irritating to skin, respiratory organs, and eyes.

Function

1. Salicin is used to ease pain and reduce inflammation.

2. Relieve acute and chronic pain, including headache, back and neck pain, muscle aches, and menstrual cramps; Control arthritis discomforts.

3. Relieve acute and chronic pain.

4. It has the same effect on the body as aspirin without any of the side effects.

5. It is an anti-inflammatory, a fever reducer, an analgesic, an anti-rheumatic, and an astringent. Specifically, it helps to relieve headaches.

Application

1.Anti-inflammatory, anti-rheumatic,

2.Reduce a fever,

3.Use as an analgesic and astringent,

4.Relieve headache,

5.Ease pain caused by rheumatism, arthritis, and carpal tunnel syndrome.

Gram-positive cell walls are thick and the peptidoglycan ( also known as murein) layer constitutes almost 95% of the cell wall in some gram-positive bacteria and as little as 5-10% of the cell wall in gram-negative bacteria. The gram-positive bacteria take up the crystal violet dye and are stained purple. The cell wall of some gram-positive bacteria can be completely dissolved by lysozymes which attacks the bonds between GA and MA. In other gram-positive bacteria, such as Staphylococcus aureus, the walls are resistant to the action of lysozymes. They have O-acetyl groups on carbon-6 of some MA residues. The matrix substances in the walls of gram-positive bacteria may be polysaccharides or teichoic acids. The latter are very widespread, but have been found only in gram-positive bacteria. There are two main types of teichoic acid: ribitol teichoic acids and glycerol teichoic acids. The latter one is more widespread. These acids are polymers of ribitol phosphate and glycerol phosphate, respectively, and only located on the surface of many gram-positive bacteria. However, the exact function of teichoic acid is debated and not fully understood. A major component of the gram-positive cell wall is lipoteichoic acid. One of its purposes is providing an antigenic function. The lipid element is to be found in the membrane where its adhesive properties assist in its anchoring to the membrane.

The gram-negative cell wall[edit]
Gram-negative cell walls are thin and unlike the gram-positive cell walls, they contain a thin peptidoglycan layer adjacent to the cytoplasmic membrane. Gram-negative bacteria is stained as pink colour. The chemical structure of the outer membrane’s lipopolysaccharides is often unique to specific bacterial sub-species and is responsible for many of the antigenic properties of these strains. Lipopolysaccharides, also called endotoxins, are composed of polysaccharides and lipid A which are responsible for much of the toxicity of gram-negative bacteria. It consists of characteristic lipopolysaccarides embedded in the membrane.
