How can the amino acid taurine affect the body in a negative way?

Does your text book give you some ideas on what your teacher is looking for?

No this is a project in which my group and I have to type up a report and have to be able to perform an experiment where something can be tested. There has to be an independent variable and dependent variable. We have to use equipment like a spectrophotometer, pipetting etc.

The University of Utah Health Care Center reports that consuming a single amino acid supplement like taurine can offset your natural nitrogen balance. This may lead to a decrease in your metabolic efficiency and a strain on your kidneys. Children taking taurine supplements may also experience stunted growth.

If it were me, I’d show the nitrogen balance and imbalance with taurine.

Thanks. We figured out that we would check the ph levels of the energy drinks we plan on testing and will add an acid an base to the samples to see if the concentration changes

Did your teacher specify that it must be related to human beings?

A taurine deficiency for cats can cause irreversible blindness, fwiw.
