Document Summary
What happens if you chew a cracker for the long time answer: Sugar molecules! (every single one) ***sugar molecules always. Sugar molecules are made of carbon, hydrogen and oxygen. Complex carbohydrates (polysaccharides) many sugar molecules strung together. *all carbohydrates are found in almost all foods (even in non food groups i. e. beer, potato chips etc. ) Suffix ose means sugar i. e. glucose, fructose, dextrose. Saccharide = sugar molecule i. e. mono-saccharide, disaccharide, polysaccharide. One glucose, and one glucose molecules found naturally. Galactose only found in disaccharides or polysaccharides. Monosacchardies are often only added to processed foods. Sucrose is table sugar (white sugar/brown sugar etc. ) Maltose is in fermented foods (a food additive) Lactose is milk sugar (less sweet that sucrose) **what lactose intolerant people are allergic to. Storage form of carbohydrates for plants i. e. grains, potatoes and legumes have lots. Often made of glucose, but can be other monosaccharides. Provide structure to leaves, stems etc. of plants.
