Caffeine (1,3,7-trimethylxanthine) is a plant alkaloid with a chemical structure of C8H10N4O2 (see Figure 2–1) and a molecular weight of 194.Summary. Caffeine is a drug that stimulates (increases the activity of) your brain and nervous system. Caffeine is found in many drinks such as coffee, tea, soft drinks and energy drinks.Caffeine is a stimulant present in tea, coffee, cola beverages, analgesic drugs, and agents used to increase alertness. It is also used in to prevent and treat pulmonary complications of premature birth.It contains the elements carbon, oxygen, nitrogen, and hydrogen.

What is the chemical formula of coffee?
For those who are interested, caffeine is a purine alkaloid and the molecular formula for coffeee is C8H10N4O2. This chemical formula for coffee represents the arrangement of atoms in a caffeine molecule, consisting of 8 carbon, 10 hydrogen, 4 nitrogen, and 2 oxygen atoms. In addition, caffeine has many positive actions on the brain. It can increase alertness and well-being, help concentration, improve mood and limit depression.The main constituents of coffee are caffeine, tannin, fixed oil, carbohydrates, and proteins. It contains 2–3% caffeine, 3–5% tannins, 13% proteins, and 10–15% fixed oils. In the seeds, caffeine is present as a salt of chlorogenic acid (CGA). Also it contains oil and wax [2].Coffee contains a number of useful nutrients, including riboflavin (vitamin B2), niacin (vitamin B3), magnesium, potassium, and various phenolic compounds, or antioxidants. Some experts suggest that these and other ingredients in coffee can benefit the human body in various ways.Studies have found caffeine can do both good and harm. People who regularly drink coffee may be less likely to develop chronic illnesses, such as cardiovascular disease, diabetes, Parkinson’s disease and some cancers.

It is a natural alkaloid that, together with theophylline (1,3-dimethylxanthine), theobromine (3,7-dimethylxanthine), and paraxanthine (1,7-dimethylxanthine), belongs to methylxanthines. The molecular formula C 8H 10N 4O 2 may refer to: Enprofylline, a xanthine derivative used in the treatment of asthma. Caffeine, the world’s most widely consumed psychoactive drug, present in coffee, chocolate, black and green tea, energy drinks, and more.Caffeine. The best known N compound is caffeine (1,3,7-trimethylxanthine) because of its physiological effects (stimulation of the central nervous system, increased blood circulation, and respiration).
What pH is coffee?
H of Coffee The potential of hydrogen or pH value of coffee on average stays between 4. A low acid coffee has a pH value closer to 5. H scale. For comparison, a pH of 7 is neutral, with pure water being the only one with that pH value. H of Coffee The potential of hydrogen or pH value of coffee on average stays between 4. A low acid coffee has a pH value closer to 5. H scale. For comparison, a pH of 7 is neutral, with pure water being the only one with that pH value.Coffee is a drink that is used all over the world. On the pH meter, its pH is around 5. But the roasted coffee beans are less acidic. Therefore, coffee is slightly acidic.In solid roasted coffee, caffeine likely partially exists as salts, but my guess is not really the majority. Wiki lists the pKa of caffeine as -0. So best case, at pH 1.Yes, caffeine is acidic in nature, and in fact it contains a lot of different acids. Because caffeine naturally contains a lot of acids, there is a tendency for people to experience discomfort in the form of a burning sensation in the stomach or oesophagus caused by too much acidity in the body.Most coffee varieties are acidic, with an average pH value of 4. Among the countless compounds in this beverage, the brewing process releases nine major acids that contribute to its unique flavor profile.
What is the biological name of coffee?
Coffea arabica is the botanical name for coffee. It is Coffea arabica which is responsible for approximately 60-80% of coffee production all over the world. The Coffea arabica bean is widespread, delicate, and vulnerable to pests. It needs a subtropical climate to grow properly. The scientific name for coffee is Coffea arabica. The bean is widely grown, fragile, and pest-prone. Arabica coffee beans differ from Robusta coffee beans(C.Traditionally, India has been a noted producer of Arabica coffee but in the last decade robusta beans are growing substantially due to high yields, which now account for over 60 percent of coffee produced in India.The four main coffee types are Arabica, Robusta, Excelsa, and Liberica and all four of them have radically different taste profiles. Looking for coffee beans?Yes, that’s correct – NESCAFÉ is made from coffee only. We carefully select and blend two main types of coffee bean – Arabica beans, and Robusta beans. Arabica beans – grown in Latin America, East Africa and Asia – are longer, and make a sweeter, more delicate cup of coffee.
