Brief Introduction
Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, berries, Ginkgo biloba, St. John’s wort, American elder, and others. Buckwheat tea has a large amount of quercetin. People use quercetin as a medicine.
Quercetin is used for treating conditions of the heart and blood vessels including “hardening of the arteries” (atherosclerosis), high cholesterol, heart disease, and circulation problems. It is also used for diabetes, cataracts, hay fever, peptic ulcer, schizophrenia, inflammation, asthma, gout, viral infections, chronic fatigue syndrome (CFS), preventing cancer, and for treating chronic infections of the prostate. Quercetin is also used to increase endurance and improve athletic performance.
Main Function
1.Quercetin may expel phlegm and arrest coughing, it can also be used as anti-asthmatic.
2. Quercetin has anticancer activity, inhibits PI3-kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors.
3.Quercetin may inhibit histamine release from basophils and mast cells.
4. Quercetin may control the spread of certain viruses within the body.
5, Quercetin may help reduce tissue destruction.
6.Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis

Condensation polymers are formed when monomers join together, and in the process also form a separate small molecule such as a water molecule. The ends of the monomer molecules must have functional groups that can join with other functional groups on neighbouring molecules.
Condensation polymerisation is the process in which two monomers combine with the elimination of a smaller molecule. One way that two different monomers can combine and in doing so lose a molecule of water and represents condensation polymerisation. This process continues and each remaining end joins with another monomer—each time lengthening the chain. One way to think of this is a “head-to-tail” joining.
Synthetic condensation polymers include nylons and polyesters. Natural condensation polymers include cellulose, cotton, wool, and silk.
Cellulose is a complex carbohydrate or polysaccharide. It is the most abundant biopolymer in nature. Carbohydrates consist of molecules containing C, H and O atoms. Carbohydrates contain many alcohol functional groups.
• Cellulose consists of long chains of β-glucose monomers.
• Glucose is an example of a simple carbohydrate or monosaccharide.
Structure of glucose :
Glucose (C6H12O6) is a ring molecule. The carbon atoms in the ring are numbered as shown. The –OH functional groups may be orientated above or below the plane of the ring. These different orientations at C, produce the alpha and beta forms of the glucose monomers.
• Glucose is an organic compound
• Ring can open up in solution to form a straight-chain structure. Open and chain forms are in equilibrium that cause glucose to exist as anomers, β-glucose and α-glucose.
Biopolymer is a naturally occurring polymer such as cellulose, starch, gluten, DNA and protein.
Formation of cellulose:
Cellulose is a condensation polymer which is formed when glucose monomers condense together through beta-1,4-glycosidic bonds. This involves a reaction between the –OH groups at the C1 and C4 carbons of adjacent glucose molecules.
The process begins by the condensation reaction between two glucose monomers to form a beta-maltose dimer. A water molecule is eliminated during this reaction. More glucose monomers condense and the chain grows until about 10 000 glucose monomers are linked in long, unbranched, ribbon-like strands.
Strong hydrogen bonding exists between –OH groups of neighbouring, close-packed strands. This produces a water-insoluble polymer with great strength and rigidity. Plants use cellulose as a structural carbohydrate for their cell walls.
