- AMP in the form of cyclic AMP is very important as it acts as a second messenger system and is essential for regulated intracellular signals. It may convert into ATP by the enzyme action adenylase cyclase and this is regulated by glucagon or adrenaline hormones.
- It is necessary for the synthesis of ADP, ATP, and RNA.

- Vitamin B8 also provides relief if a patient is suffering from diabetic neuropathy.

- This vitamin deficiency leads to the low synthesis of ADP, ATP, and RNA in the body.
- There occurs inhibition in the breakdown of food in order to produce energy.
- Its deficiency results in a reduction in hormonal function.
- Weak muscles, lack of appetite, muscle cramps, fatigue, generalized body aches, hair loss and pricking sensation in the skin may be felt by the patient.
