hydrogen atoms‚ four nitrogen atoms‚ and two oxygen atoms. Theobromine is very similar to caffeine but is ten times weaker. Caffeine has two more hydrogen atoms than theobromine. The structure of theobromine also contains two amide groups and three amine groups. Theobromine naturally occurs in cacao beans and is found in all chocolate products. It is what is toxic in chocolate to animals. Cardiac and central nervous system distress in dogs can be caused by 100-200 mg of theobromine per kg of

of humans. Nitrate is commonly found in fertilisers for food crops so it’s also found on the outside of fruits and vegetables (Mygind‚ 1991). This is relevant because nitrite can have consequences for our overall health. It can react with secondary amines to form nitrosamines. Research has shown that some nitrosamines can cause cancer (Mygind‚ 1991). Furthermore‚ in our blood there is a reaction between nitrite and haemoglobin. Nitrite can oxidise the haemoglobin in the blood to methaemoglobin which

Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics

Bad eating habits are common. It is easy to operate on automatic when it comes to food. Living in a fast-paced society often makes it so you have to eat on the run‚ skip meals‚ eat whatever is fast and easy or use food to relieve stress. We eat a lot of bad foods everyday‚ but we don’t think what impact on our health it makes. I watch a video about Top 10 Bad Foods and now I can say which products and drinks disappear forever from my diet. So Top 10 Bad Foods are : 1. Soda 2. Doughnuts

A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.
