If it is criminal to leave a 13-year old alone to babysit children, then I am one guilty editor with a lot of guilty girlfriends. The summer I turned 12, I was working as a mother's helper for a woman who had two young girls. She would regularly leave me unattended to watch the girls while she ran errands.
Monosaccharides are the simplest form of carbohydrates and may be subcategorized as aldoses or ketoses. The sugar is an aldose if it contains an aldehyde functional group. A ketose signifies that the sugar contains a ketone functional group.
A disaccharide (also called a double sugar or biose) is the sugar formed when two monosaccharides (simple sugars) are joined. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose. Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides). The most common types of disaccharidesâsucrose, lactose, and maltoseâhave twelve carbon atoms, with the general formula C12H22O11.
