Indeed, steroid hormones have an important role in the well-being of the individual through specialized cells (having specific receptors). Take the example of vitamin D.
Vitamin D is involved in calcium and phosphorus absorption by the intestines, as well as in their reabsorption by the kidneys. It is involved also in bone mineralization of the skeleton and joints, as well as on muscle tone.
The mechanism of action of the hormone is identical to the scheme:
Its carrier is vitamin D-binding protein
The cell may be an intestinal cell, bone cells or renal cells.
The vitamin acts on the DNA is activating / inhibiting certain genes encoding proteins so as to increase the level of calcium in blood.
The causes of changing the pH of milk into yogurt are that the lactose in the milk is converted into lactic acid, which leaves the pH.
<u>Explanation:</u>
When the pH drops below pH5. The micelles of the caseins, a hydrophobic protein, lose its territory structure due to the protonation of the amino acid residues.
So the production of the amino acids forms the basic structure and texture of the yogurt. To turn the milk into the yogurt the first process is to ferment the milk and turning the lactose sugar in the milk into the lactic acid, then the lactic acid converted into the yogurt.
