What are different types of disaccharides? How are they produced? Mention their sources.

Disaccharides are carbohydrates composed of two monosaccharide units linked by glycosidic bonds. The three main types of disaccharides are:

1. Sucrose (Glucose + Fructose):

Found in sugarcane, fruits, and honey.

Produced through photosynthesis in plants, where glucose and fructose molecules combine.

2. Lactose (Glucose + Galactose):

Found in milk and dairy products.

Synthesized in mammary glands of mammals and provides energy to infants.

3. Maltose (Glucose + Glucose):

Found in germinating grains, malted foods, and beer production.

Produced during starch digestion by the action of amylase enzymes.
