The Importance Of Caffeine

1. Introduction
The power source and an engine which provides a driving force and fuel to the body is energy, which is not lost but, maintained by exertion and usage. The breakage of intake food and absorption of minerals provide the energy to our body cells for doing metabolic activities, thus food is important. According to the Newton law of motion, our body was planned to be in motion, when we are in an apparent motion, body provides energy to carry out its activities which can be metabolic, physical and mental etc. These motions if not there, can create energy imbalance which would result in shutdown of activities. When energy reserves start to decrease, we feel exhausted and fatigued. This provides an indication that ‘fuel’ is required

It is absorbed and metabolized in the liver which catalyses it into paraxanthine , theobromine and theophylline as shown in the below figure. It is distributed within 45 min to all over body and circulates from blood to all tissues. Caffeine has a 10-35% protein concentration. There is about 56 -100 mg /100 ml caffeine in brewed coffee, 20-73 mg/100 ml in instant coffee or tea and 31 mg/100 ml of caffeine in widely used energy drinks. Our urban, advanced elegant culture and media is responsible for increased advertisement of these energy boosters that are now getting widespread popularity all over the

Xanthosine acts as a substrate and is converted into caeffine .Howeever, in the minor route, xanthosine is converted into xanthine which is follwed by the caeffine degradation into NH3 and CO2 as shown by the purine catabolism pathway.

1.3 The science of Coffee, tea and energy drinks
Caeffine is the major ingrediant of coffee, tea and energy drinks but there are some other components in these beverages that play a side role with caeffine. Looking the chemistry of coffee , tea and energy drinks, besides caffiene, other the chemical composition of ingredients have been found in these drinks.
Chemical composition of Coffee:
 It has an alkaloid which is Trigonelline which is responsible for giving aromas of sweet caramel by broken down into aromatic compounds pyridines.
 It has Carbohydrates, lipids, vitamins and protein
 It has an aliphatic acids which are :acetic, citric, maleic, pyruvic and lactic
 Chlorogenic acids and antioxidants
