  3. 3.  Tyrosine (Greece: tyros, meaning cheese, because it was discovered first by cheese) 4-hydroxyphenylalanine tyrosine, Tyr, Y is one of the 20 amino acids of the protein. Systematic name Acid S-2-amino-3-(4-hydroxy-phenyl)-propanoat, abbreviated Tyr-Y, the genetic code UAU, UAC, chemical formula C9H11NO3, molecular mass 181,19 g mol-1, 343 ° C melting point, density 1,456 g cm-3, isoelectric point 5,66. Tyrosine has a cluster of phenol (phenyl with one extra hydroxyl group)It has a cluster of phenol (phenyl with one extra hydroxyl group). A common form is L-tyrosine (S-tyrosine), which is also found in three isomers: the structure, meta and Ortho.  Formation of tyrosine using raw ingredients phenylalanine hydroxylase enzymes fenilalanin. This just makes the enzyme-tyrosine. The other two isomers are formed in case of "attacks" of free radical oxidative condition (State of stress).
  4. 4. Oxidation of tyrosine producing monoiodotirosin (MIT) and iodotirosin (DIT). A combination of two molecules of DIT produces the hormones thyroxine (T4), while the combination of molecules through a process of DIT and MIT monodeiodinasi produce hormones T3. Cheese is a very rich intake of calcium, phosphorus, zinc, vitamin A, riboflavin, and vitamin B12. One serving or approximately 30 grams of cheddar cheese alone is contains 200 gr calcium or calcium deposits equivalent in pure milk are medium-sized.

The cheese was able to inhibit tooth email, because the fragility of cheese can stimulate the flow of saliva and relieve a sour taste in the mouth cavity.

  6. 6. Cheese not only serves as a deterrent cavities, but also can help cure a tooth hollow.

For example, the content of casein in cheese can aggravate the condition of patients with autism. While the lactose in cheese "young" or harmful for people with cheedar cheese in-tolerance lactose.

  8. 8. Question 1. its substance can relieve stress and create we can sleep better? Answer : is tryptophan 2. Why is cheese good to protect your teeth? Answer : because the cheese are calcium and phosphorus which is able to inhibit the fragility of email, cheese can stimulate the flow of saliva and relieve a sour taste in the mouth can cause cavities.
