Caffeine

Caffeine is a polar molecule thus it has hydrophobic portions, and dichloromethane is s polar organic solvent which is fairly good at dissolving most organic molecules. In water caffeine dissolves for the most part via formation of hydrogen bonds where atoms with free electron pairs are involved, and the solubility of caffeine in water in 2.2mg/mL at 25 C, 180 mg/mL at 80 C, and 670 mg/mL at 100 C. where caffeine is not all soluble in water at room temperatureWhen caffeine is brought in close contact with dichloromethane most of the caffeine migrates into the organic layer.

Maybe you're using too much of it. You only need one regular-sized cup of coffee to make you alert - that's an ordinary cup, not a grande Starbucks or super-sized 7-eleven cup! Using too much caffeine can have the opposite effect because it burns up your energy too fast and you end up feeling tired.

Crystal Light has recently begun producing Crystal Light Energy, which contains 60mg of caffeine per serving, or 120mg caffeine per packet

Based on regular serving sizes, coffee contains more caffeine. There are 95mg in a standard 8oz cup of coffee and 32mg in a 12oz can of Classic Coca-Cola.

nah they dont

No, milk does not contain any caffeine. Caffeine is a stimulant found in coffee, tea, and some soft drinks and energy drinks.

A 20oz bottle of Mello Yello has 86mg of caffeine. So a 12oz serving should have around 51 mg.

Unless it specifically states "caffeine-free" on the label, YES.

Chai tea is made with black tea as a base, with spices and flavourings added.

Black tea has caffeine in it.

Decaffeinated teas have some (not all) of the caffeine removed.

There are herbal chai teas available that are made without black tea in them, so read the label carefully.

Vicodin is a combination product which combines hydrocodone (a narcotic pain reliever) with acetaminophen (a non-narcotic, non-aspirin pain reliever and fever reducer). The product does not contain caffeine.

Based on its structure, it does NOT have a chiral center so NO

yes but you should not, it can affect how it works. Amoxicillin should be taken with food. 500 mg every 6-8 hours for 8-10 days depending on what you have. but no less than 8 days. Drink lots of water, eat real good and it will work you can take ambroxol for your cough or ask for something stronger if you need it.

Matcha tea, as a green tea, contains small levels of caffeine.

The ratio is about 35mg of caffeine per 1g of matcha tea.

Unlike caffeine in coffee, this is absorbed slowly into the blood stream and has longer lasting effects.

I'm pretty sure it doesn't; that would be weird, don't you think?

it stumps growth and somthing else, ill return

By stimulating the Adenosine receptors in the brain and around the body, giving you the impression that you have more energy than you actually do.

I think that you should stop drinking caffeine because it stops you from growing. I don't want to stay the same height. But that's just my opinion.

You should stop drinking caffeine because it reduces the risk of having heart disease and increases the cAMP in the heart cells. Also, it could reduce the risk of developing Parkinson's disease.

According to the American Heart Association (Dated April 14, 2010)

"Many studies have been done to see if there's a direct link between caffeine, coffee drinking and coronary heart disease. The results are conflicting."

The study has been added to the related links section below.

No, it is a stimulant.

re always awake and shaking i know someone who experianced this!!:)x

No. Pure vanilla extract should contain only vanilla & alcohol.

There are 29 bonds in caffeine! How did I get my answer?

The chemical formula for caffeine is C8H10N4O2

1. Count total octet electrons

64+20+32+16=132

2. Count the # of valence electrons in the molecule.

32+10+20+12=74

3. Subtract valence electrons from octet electrons

132-74=58

4. Divide the bonding electrons by 2 to find the number of bonds.

58/2=29

Not ALL orange soda's are caffiene free. Many are, but for instance Sunkist diet orange has caffeine in it. I would always look at the label before assuming because it is orange, it is caffeine-free.

I am on Metoprolol twice 25mg a day for a First time A FIB episode Oct 29th. never felt a shakiness inside before. It's like a jittery feeling inside my chest. my heart rate however will show 62. Can it be a vitamin deficiency? Can it be the med itself? I dont evenhave to drink coffee to feel this way. This medication is for High blood pressure and angina. I didnt have either of this before. Now i am experiencing a dull ache on my left side off and on and an increase in my blood pressure to around 130 to 140 / 86-105. My doc told me to increase my medication to double 50mg twice a day. I have done this for 2 days with no difference. Just curious if anyone has ever asked this question

hell yeah thats how i kill them ;) <3

There are many types of hallucinogenic drugs. There are several categories of hallucinogen. The three main categories of hallucinogenic drugs are the psychedelics, dissociatives and deliriants. Some famous psychedelics include LSD-25, Psilocybin, Mescaline, DMT, 2C-B and Cannabis. Some famous dissociatives include Ketamine, Dextromethorphan, Nitrous Oxide and PCP. Famous deliriants include Atropine, Scopolamine and Diphenhydramine. The psychedelic hallucinogens mostly work by affecting serotonin receptors in the brain. Dissociatives affect NMDA, Dopamine, and/or Opioid receptors. Deliriants typically affect Acetylcholine. Each of these three categories has many, many known drugs in it and there will be more discovered in the future. Some occur naturally in nature, some are created synthetically, others are modified from their natural form to become semi-synthetic. In addition, each category of hallucinogen contains drugs with distinctly different effects than the drugs from another category. Additionally, drugs of the same category can have different effects.

White chocolate contains only cocoa butter, not cocoa solids. Caffeine is only in the solids so white chocolate does not have any.
