Caffeine is an alkaloid that acts as a chemical stimulant, called 1,3,7-trimethylxanthine.
The pure anhydrous form of caffeine is coloured white. It is easily soluble in lukewarm and hot water, and slightly soluble in water (room temperature). Students can refer to the Extramarks website for Caffeine Formula.
Structure of caffeine
The representation of Caffeine Formula is a purine-like heterocycle. Positions 2 and 6 are carbonyl groups, and positions 1, 3, and 9 are methyl groups. The main source of Caffeine is coffee beans. Apart from that, it is also found in cacao, tea tree, and kola nut. Coffee beans are one of the most common sources of caffeine, and many people drink coffee regularly for the effects of caffeine.
Chemical composition of Caffeine:
The compound Caffeine is composed of Carbon, Nitrogen, Hydrogen, and Oxygen atoms. It is made up of 8 Carbon atoms, 10 Hydrogen atoms, 4 Nitrogen atoms and 2 Oxygen atoms. Caffeine Formula can be referred to on Extramarks.
Caffeine Chemical Formula
The chemical names for Caffeine are trimethylxanthine, mateine, theine, galanine, and methyl theobromine. It has a sour taste and a density of 1.23 gmL1. It has a melting point of 235°C and a boiling point of 178°C. Caffeine is easily soluble in water and liquids. It is a CNS (central nervous system) booster. The implied response reversibly prevents the action of adenosine at specific receptors, thereby strengthening the nervous system. The caffeine molecule can function in this way because its structure is very similar to that of the adenosine molecule, especially as far as the nitrogenous base adenine is concerned. Due to their similarity, they are especially functionally equivalent to the nitrogenous base adenine. Students can visit the Extramarks website for Caffeine Formula.
Caffeine Structural Formula
Caffeine is composed of heterocycles that are similar in structure to purine rings. Its structure resembles that of adenine (the nucleobase found in DNA) and guanine (the nucleobase found in DNA and RNA). Students are advised to check Caffeine Formula
- Synthesis of caffeine
Caffeine can be synthesised by both biosynthetic and chemosynthetic pathways.
- The biosynthetic pathways for caffeine synthesis are:
The caffeine biosynthetic pathway involves the conversion of xanthosine to 7-methylxanthosine by the action of the enzyme 7-methylxanthosine synthase. The 7-methylxanthosine produced is converted to 7-methylxanthine by the action of N-methylnucleosidase. The resulting product is further converted to theobromine and finally to caffeine by the action of the enzymes theobromine synthase and caffeine synthase, respectively. Students must see Caffeine Formula on Extramarks.
