Document Summary
Carbs: one of the 3 macronutrients, a primary energy source, especially for nerve cells, composed of carbon, hydrogen, oxygen, good source include fruits, veggies, and grains. Glucose: the most abundant carb, used as a building block for other carb molecules, produced by plants through phosynthesis. Photosynthesis: energy is taken in from the sun, glucose is stored in plant, co2 is in the air. Simple carbs: contain 1 or 2 molecules, monosaccharides contain only 1 molecule (glucose, fructose, galactose, disaccharides contain 2 molecules (lactose, maltose, sucrose) Monosaccharides: glucose: most abundant sugar in our diet; good energy source. Fructose: sweetest natural sugar; found in fruit; high fructose corn syrup: galactose: doenst occur alone in foods; binds with glucose to form lactose. Disaccharides: glucose + galactose = lactose and is also called milk sugar, glucose + glucose = maltose. Maltose molecules join in food to form starch molecules; by-product of fermentation process: glucose + fructose = sucrose.
