|
|
glycosidic; galactose
|

|
hydrogen; sucrose
|

Explanation:
Detailed explanation-1: -The bond formed between glucose and galactose monosaccharides to produce the disaccharide lactose is a -1, 4-glycosidic bond. This bond is formed between C1 of galactose and C4 of glucose, and it happens as a reduction process.
Detailed explanation-2: -Lactose is a disaccharide formed by the formation of a glycosidic bond between glucose and galactose.
Detailed explanation-3: -For example, milk sugar (lactose) is a disaccharide made by condensation of one molecule of each of the monosaccharides glucose and galactose, whereas the disaccharide sucrose in sugar cane and sugar beet, is a condensation product of glucose and fructose.
