Caffeine is a natural stimulant in your body. Drinking sodas, coffee, tea or energy drinks when you have a UTI can stimulate your digestive and urinary tract -- not a good idea when your goal is to soothe instead. Caffeine-containing beverages like coffee also can have a dehydrating effect as well.
Deamination is the removal of an amine group from a molecule. Enzymes that catalyse this reaction are called deaminases. In the human body, deamination takes place primarily in the liver, however glutamate is also deaminated in the kidneys. Deamination is the process by which amino acids are broken down if there is an excess of protein intake. The amino group is removed from the amino acid and converted to ammonia. The rest of the amino acid is made up of mostly carbon and hydrogen, and is recycled or oxidized for energy.
denaturation. For proteins, a process in which a protein unravels and loses its native conformation, thereby becoming biologically inactive. For DNA, the separation of the two strands of the double helix. Denaturation occurs under extreme conditions of pH, salt concentration, and temperature.
