Vitamin E (Anti ageing Vitamin)

-

 Alpha tocopherol (Biologically active form of Vit E) is the most potent antioxidant of nature.

Biochemical role: 

It quenches lipid peroxidation chain and protect plasma membrane from attack of Free radical 

Metabolism:

As it is Fat soluble vitamin it is absorbed with Fat, bile salts and transported as chylomicrons 

Normal Blood level = 0.5-1mg/dl

Sources:

Vegetabel oil like sunflower,  wheat germ , cotton seed oil 

Fish liver oil is devoid of Vit E

As intake of PUFA ( Polyunsaturated fatty acids) increases Vit E should be increased in order to cope up with harmful effects of it 

Why known as anti ageing vitamin?

As Vit E quenches lipid peroxidation chain reaction thus production of free radical are decrease hence there is less damage to Cell membrane , this explains its anti ageing effect

 Human body daily encounter numerous pathogens and foreign bodies. To cope up with its harmful effect our body has defence mechanism i.e. Immune system.To assist immune system there is complementary system in our body which serves as 2nd line of defence. This is basic definition of complementary system of human body.  Complementary system consists of various protein primarily synthesised in liver and they are present in our blood stream in an inactivated form. As soon as our body encounter pathogens or foreign antigen they become active and start their function in series of steps. Complementary protein 1 further activates other protein in series of step which will be discussed in other blog and they develop a system which by following ways kills the foreign body (Antigen, Bacteria, Fungi etc.. ) 1) By making pore in cell membrane of foreign body  2) By activating Neutrophil   3) By activating Mast cells which secrete histamine and other lysosomal products  Thi...

 What is ELISA TEST ? ELISA Test is commonly used to test antigen antibody protein glycoprotein present in body. This test is more commonly used than Radioactive Immunoassay (RIA) because of it s simplicity. How is Direct ELISA performed for antibody detection? ELISA is performed in special plate for detection of antibody by Direct ELISA steps are as Follows  1) The plate is coated with specific antigen against which the antibody is to be detected  2) Then the serum is added in the plate (serum contains various antibody)  3) Now if the Antibody is present in the serum it will bind to antigen coated in the plate tightly  4) The plate is now washed so that unwanted antibody and other products are washed away and only Antigen-antibody  complex remains 5) The antibodies are coated with special enzyme which gives colorful products on reactions with substrate  6) The substrate are added to the plate and if the antibodies are present then it will give colorfu...
