What are the organic compounds in skim milk?

Skim milk primarily contains organic compounds such as proteins, lactose, and various vitamins and minerals. The main proteins are casein and whey proteins, which are vital for muscle repair and growth. Lactose, the sugar in milk, provides energy, while vitamins like B12 and riboflavin contribute to metabolic processes. Skim milk also contains small amounts of fatty acids and other bioactive compounds, although the fat content is significantly reduced compared to whole milk.
