droplets, and the electrically charged heads project from the droplets and shield the droplets from each other The emulsion of fat droplets is now stable These “surface-active” molecules have many other applications as well For example, monoglycerides have been used for decades in the baking business because they help retard staling, apparently by complexing with amylose and blocking starch retrogradation Carbohydrates The name for this large group of molecules comes from the early idea that they were made up of carbon and water They are indeed made up of carbon, hydrogen, and oxygen atoms, though the oxygen and hydrogen are not found as intact water complexes within the molecules Carbohydrates are produced by all plants and animals for the purpose of storing chemical energy, and by plants to make a supporting skeleton for its cells Simple sugars and starch are energy stores, while pectins, cellulose, and other cell-wall carbohydrates are the plant’s structural materials SUGARS Sugars are the simplest carbohydrates There are many different kinds of sugar molecules, each distinguished by the number of carbon atoms it contains, and then by the particular arrangement it assumes Five-carbon sugars are especially important to all life because two of them, ribose and deoxyribose, form the backbones of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), the carriers of the genetic code And the 6-carbon sugar glucose is the molecule from which most living things obtain the energy to run the biochemical machinery of their cells Sugars are such an important nutrient that we have a ... are especially important to all life because two of them, ribose and deoxyribose, form the backbones of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), the carriers of the genetic code And the 6-carbon sugar glucose is the molecule from which most...
