Something About Caffeine Coffee is one of the most popular beverages, and you can find a cup of it everywhere on the road, but what do we know about the caffeine in coffee? Introduction The systematic name for caffeine is 1,3,7-trimethyl-2,6-dioxopurine, a central nervous system stimulant. Caffeine is a phytoalkaline, which is a chemical extracted from plants and is commonly found in coffee beans, tea leaves, and cocoa beans. Caffeine has a high solubility in water, 67 g/100 g of water at 100°C, so it can be extracted from tea leaves using hot water. The amount of caffeine in coffee varies depending on the species of coffee tree or the method of coffee production. Generally speaking, a 150ml cup of coffee contains approximately 100mg of caffeine, with chocolate, tea, and coke containing smaller amounts of caffeine. History Around the ninth century, people observed that goats would become hyperactive after eating the fruit of the coffee tree and thus discovered that chewing the fruit and leaves of the coffee tree had a stimulating effect. Still, it was not until many years later that it was known that brewing the plant in hot water could increase the stimulating effect. If you drink coffee regularly, you need to pay attention to your daily caffeine intake.

Still, it was not until the Ottoman Turkish Empire attacked Vienna in the seventeenth century that coffee was introduced to Europe. The first coffee shop was opened in Italy in 1654, while America was not introduced to Virginia until 1607. Effects and metabolism Caffeine is a substance that interferes with neurotransmitters, and its pharmacological effects are indeed stimulant, increasing alertness. Caffeine dilates the coronary arteries that supply oxygen to the heart, and the blood vessels in the brain constrict, reducing the amount of blood entering the brain and therefore reducing headaches. Most of the metabolism of caffeine takes place in the liver, but after drinking coffee, caffeine is distributed throughout the body. The half-life of caffeine (i.e., the time it takes for the amount of caffeine to decrease to half its value after intake) varies from person to person, depending on the age, liver function, whether the person is a smoker or pregnant, etc., but generally speaking it is about 3-6 hours. Women, in general, metabolize caffeine about 20-30% faster than men, and women who are ovulating will metabolize it even faster. Caffeine metabolism is also particularly rapid in smokers, so coffee levels are not always high enough. If you want to drink fresher coffee, a complete and free coffee roast levels chart can help you roast fresher coffee beans. Physiological mechanisms Why is coffee so refreshing? It is because caffeine inhibits the conversion of c-AMP to 5'AMP, which is a protein that activates the breakdown of liver glucose, but can easily be converted to 5'AMP, which reduces the concentration of c-AMP and the rate of liver glucose breakdown. Caffeine inhibits this reaction, so c-AMP can be used in higher concentrations to assist in the breakdown of liver sugar into glucose for energy production, which indirectly promotes energy production. Overconsumption Usually, 1.5mg of caffeine per kilogram of body weight is enough to have a stimulating effect. Still, at around 5mg, it can cause over-excitement in the central nervous system, resulting in symptoms such as anxiety, shaking, shortness of breath, diuresis, and insomnia. It can even be fatal at 150mg per kilogram of body weight. If caffeine is consumed in large amounts over a long period of time, it can lead to "chronic caffeine toxicity." This is a high dependence on caffeine. Suppose a chronically caffeinated person stops consuming caffeine. In that case, it can cause adverse physical and psychological reactions such as anxiety, insomnia, convulsions, and palpitations, and in the long term can even lead to a range of mental disorders.

The average coffee drinker consumes 2.6 cups of coffee per day and 363.5 mg of caffeine. Worldwide, 120,000 metric tons of caffeine are consumed each year, and the average adult consumes 200 mg of caffeine per day. This shows that caffeine is an essential chemical in the lives of many modern people! References: Do Darker Roasted Coffee Beans Have More Caffeine? - Topgrade
