Transcript of Chemistry Functional Groups in Food

Chocolate Five Ingredients in Chocolate
Thiamine
Riboflavin
Theobromine
Phenylethylamine
Seratonin What is Thiamine?
What Functional Group is it in?
What is its purpose? Thiamine is also known as vitamin B1
The body uses vitamin B1 to break down sugars
It is in a functional group called Pyrophosphate or Diphosphate
This means it is an Ester containing two phosphate groups This is the structural formula for Thiamine The ester with the two
phosphate groups is also attached to two benzene rings and an amine functional group (NH2) The next ingredient is Riboflavin
It is also known as Vitamin B2 Riboflavin is used to convert food (such as
carbohydrates) into something your body
can use as a fuel (such as glucose)
Riboflavin can also be used with a UV light
to reduce harmful pathogens in donated
blood This is the formula structure for Riboflavin
It contains the Ketone functional group with three benzene rings as well as a butyl branch with hydroxides attached Next is Theobromine!!! Theobromine is a bitter alkaloid (means it contains basic nitrogen atoms) found in the cocoa plant
It has a caffeine effect on the human nervous system Theobromine's stuctural formula contains two methyl branches of CH3 and two oxygen ketones Phenylethylamine is also an ingredient in chocolate... my favorite ingredient... let's see why! Phenylethylamine is a chemical that raises blood pressure and blood glucose levels
This makes one feel more alert and elevates one's mood as well Phenylethylamine has a rather simple structural formula containing one benzene ring attached to an amine functional group Last but not least is Serotonin!!! Serotonin is found in the gastrointestinal (GI) tract as well as in the central nervous system
It regulates
Mood
Sleep
Appetite
Muscle contractions
Functions such as memory and learning
Blood clotting between blood platelets Serotonin's structural formula contains and amine functional group as well as an alcohol functional group
This combined with the different alkene bonds is known as a entirely different functional group called indole The End
