Document Summary
Energy source for the body especially nerve cells and the. Obtained through plant foods (fruits, veggies, grains) Most abundant form of carbs/ an abundant sugar molecule. A monosaccharide that can combine with other sugars to form. Preferred source of energy for brain and cells. Produced by plants through photosynthesis disaccharides and complex carbs: photosynthesis: water, co2 and energy combined to produce glucose. Plants green pigment, chlorophyll, absorbs sunlight to provide energy to produce glucose. Water is absorbed from the roots and combines with co2 present in the leaves to produce glucose: plants store glucose to support growth and when eaten, out bodies use the stored glucose. Simple vs complex based on number of molecules of sugar present. Monosaccharide or a disaccharide (one or two sugar molecules: monosaccharide- simplest carb. Different arrangement of atoms = different sweetness (all monosaccharides have 6 c, 12 h, and 6 o )
