Yes, milk is converted into curd through a process called fermentation, in which specific bacteria, such as Lactobacillus, convert lactose (milk sugar) into lactic acid. This causes the milk proteins to coagulate and thicken, resulting in the formation of curd.
The curd is the fat in the milk that sticks together. ------------------------------------------------------------------- I think it is the proteins rather than the fat that are responsible for the formation of curd - after all you can get fat free curd cheese.
When milk is converted into curd through the process of fermentation, the entropy of the system decreases. This is because the transformation from milk to curd involves molecules becoming more ordered and structured, leading to a decrease in randomness and disorder within the system. As a result, the entropy of the milk-curd system decreases, following the second law of thermodynamics which states that in a closed system, entropy tends to increase over time.
It is an endothermic reaction. It absorbs heat while freezing.
You taste lactic acid when the milk becomes sour. Acids, in general, sour.
To convert milk into curd, heat the milk to a lukewarm temperature, add a small amount of curd culture or curd from a previous batch, and let it sit undisturbed in a warm place for 6-8 hours to allow the milk to ferment and curdle. The bacteria in the culture will convert the sugars in the milk into lactic acid, thickening the milk and turning it into curd.

Lactobacillus is a type of beneficial bacteria that plays a key role in the fermentation process that turns milk into curd. When milk is inoculated with Lactobacillus, it ferments the lactose (milk sugar) and converts it into lactic acid. This acid causes the proteins in milk, particularly casein, to coagulate and form the thick, creamy texture of curd. The fermentation process also enhances the nutritional value of the milk by introducing probiotics, which promote gut health.

Casein in milk needs to be converted to curd, which is essentially coagulated casein protein, in order to make it easier to digest and for better nutrient absorption. Curd formation also helps in improving the texture and flavor of the milk. Additionally, curd contains beneficial probiotics that aid in digestion.
Curd is a solid form of dairy product that is formed by coagulating milk proteins. It has a soft, slightly lumpy texture.
Lactobacillus casei is the bacterium present in curd. It produces lactic acid, which in turn reduces the pH and coagulates milk proteins (primarily casein) forming curd.
When you make curd from milk, the milk ferments due to the introduction of good bacteria like Lactobacillus. This bacteria converts the lactose in the milk into lactic acid, which thickens the milk and gives it a tangy flavor. The result is a creamy, tangy product known as curd or yogurt.
