The Agriculture Department's Handbook 8 says a slice weighs a little more than 2 ounces and contains 140 calories and 3.21 grams of fat. No pizza slices in this survey came even close to that puny size. Perhaps that is how one overweight woman rationalized her pizza lunch this way: Let's see.
Urine is made up of water as well as some chemical components. The  chemical components of urine are ph, glucose, ketones, blood,  bilirubin and urobilinogen, nitrates, and â¦ leukocyte esterase.3 people found this useful.ost of the toxins are rich in nitrogen such as d â¦ issolved salts, urea, and organic compounds. While water accounts for about 96% of the urine excreted by a healthy person, small amounts of other chemicals are urea, chloride, sodium, potassium, ammonia, and calcium.
Mammals metabolize ammonia into a molecule called urea: As you can see, this molecule contains two atoms of nitrogen. Although it requires metabolic energy to build, it also is less toxic than ammonia, and it requires less water to flush from the system.Your urine's main nitrogenous waste product is urea.itrogen combines with other molecules in the body to produce toxic compounds such as ammonia. And so the animal must find a way to excrete these toxins. As we already know, this is the function of the kidneys and the rest of the renal system. Ammonia has only one nitrogen per molecule, but it is quite toxic.
