Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen. There are three main types: monosaccharides, disaccharides, and polysaccharides. Glucose is a monosaccharide that can form glycosidic bonds to join with other monosaccharides and form disaccharides like maltose or polysaccharides like starch and cellulose. Glucose and fructose combine to form the disaccharide sucrose, while glucose and galactose form the disaccharide lactose. Benedict's test is used to detect the presence of reducing sugars like monosaccharides.
