BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Vitamin B12 works closely with vitamin B9, also called folate or folic acid, to help make red blood cells and to help iron work better in the body. Folate and B12 work together to produce S-adenosylmethionine (SAMe), a compound involved in immune function and mood.

Detailed explanation-2: -Folic acid also works closely with vitamin B12 to help make red blood cells and help iron work properly in the body. Vitamin B9 works with vitamins B6 and B12 and other nutrients to control blood levels of the amino acid homocysteine.

Detailed explanation-3: -The reason they are classified as different vitamins, however, is because they all serve a slightly different specific function. For example, B9 helps you avoid DNA mutations that could cause cancer, while too little B12 or B6 in your diet could cause you to have anemia.

Detailed explanation-4: -Vitamin B6 and vitamin B12 can be taken together. They are often combined in multivitamin supplements and in B-complex supplements. Vitamin B6 deficiency is uncommon, however, and usually occurs in people who have low levels of other B-complex vitamins, such as vitamin B12 and folic acid.
