The Chemistry of Milk


Milk is a liquid that is consumed from mammals that is drank by their offspring

I choose to do milk because I have always been curious what’s in my favorite drink.

It affects my life because I drink almost a gallon a day which helps build strong bones. Also i’m quite active, so to stay healthy I drink a lot of milk.

Composition of ...

Milk’s composition differs depending on type of mammal, or where and when the milk was produced. However the main composition of milk is carbohydrate (Lactose), fat, protein, vitamins and minerals, enzymes.

Main Chemicals, Compounds, Components

The two main chemicles in milk are


-lactose (carbohydrate)

Waters molecular formula for water is H20.Water is the most availble resource on Earth's surface, it covers 70 percent of the Earth. Water can exists in a liquid, solid, and gaseous state.

lactoses molecular formula for lactose is C12H22O11. Lactose is formed from galactose and glucose units. Lactose is the main carbohydrate in milk. Lactose is responsible for drawing water into the milk as it is being formed in the mammary glands of mammals.

Chemistry's Role

The chemistry behind milk components are as following;

Water is formed when it falls from clouds in the form of rain.It starts when oxygen and hydrogen bond together to create individual water molecules. Water is naturally occurring.

lactose (carbohydrate) is a sugar. Lactose is created in a lab. Its optained from galactose and glucose.

Background Research

How is it made?

Milk is a white liquid produced by the mammary glands of mammals. After that its the cows are milked twice a day using mechanical vacuum milking machines. Used to simulate the sucking of the cows offspring.

Where is it made?

Milk is produced by mammals however its made “drinkable” in the hundreds of factories that pasteurize milk.

How does it work?

Milk works by helping develope the human body. The reason for this is because the calcium in milk builds strong bones.
