As the most abundant protein in human whey and a key component in all mammalian milk, lactalbumin's primary function is to regulate the synthesis of lactose, an essential process for milk production. Beyond this fundamental role, it provides crucial nutritional and immunological benefits, especially for infants.

Lactose, the sugar found naturally in milk, accounts for 2–8% of milk by mass depending on the species. While known as milk sugar, it is chemically a disaccharide, a molecule composed of two simpler sugar units. This article explains the exact role of glucose in forming this complex sugar and how our bodies process it.

Lactose, the primary carbohydrate found in milk, is a disaccharide made of one glucose molecule and one galactose molecule. So, where does glucose come from in milk? The simple sugars needed to build this lactose are primarily derived from glucose taken directly from the bloodstream by the mammary gland.

Lactose, or 'milk sugar,' comprises about 2–8% of the milk of all mammals, making it the only common sugar of animal origin. This crucial milk sugar is produced through two distinct processes: a biological pathway in the mammary glands of mammals and an industrial method that extracts lactose from whey. Understanding how is lactose produced is key to comprehending mammalian lactation and dairy processing.

Human breast milk contains a significant amount of lactose, a carbohydrate that provides a primary source of energy for the infant's rapid growth and development. A mother's diet, therefore, plays a crucial role in the synthesis of this vital macronutrient during lactation.

The natural carbohydrates in milk primarily exist in the form of a unique sugar called lactose, a compound not simply filtered from the animal's diet but actively biosynthesized within the mammary gland during lactation. This process is crucial for providing a stable energy source for the offspring and influencing the overall volume of milk produced.
