 ... adapted to spread chlorenchyma to light. The formation of the sugar being thus a process of synthesis under action of light, is known as PHOTOSYNTHESIS. What now are the materials from which the grape sugar is constructed? The chemical formula of...

...large. For that reason, they easily change to less complex substances. Thus, the molecule of grape sugar is composed of six atoms of carbon, twelve of hydrogen and six of oxygen, but if a solution of this sugar in water is mixed with yeast, the sugar moleulc breaks down, forming... | |

...materials from which the grape sugar is constructed? The chemical formula of grape sugar is C6Hi2O6, which means of course that its molecule is composed...that part of the sugar, at least of its hydrogen; and this hypothesis is fully confirmed by research. The water is absorbed into the plant from the soil... | |

...materials from which the grape sugar is constructed ? The chemical formula of grape sugar is C6Hi2O6, which means of course that its molecule is composed...of hydrogen, and six of oxygen. Now the proportions H^Oj in this formula recall the familiar H2O, suggesting that water may be the source of that part... | |

...(there are many kinds) has the formula CeHi^Oe, which indicates that a molecule of this kind of sugar is composed of six atoms of carbon, twelve of hydrogen, and six of oxygen. The proportion of carbon in different carbohydrates varies, but that of hydrogen and oxygen always... | |

...and the elements of water ; thus, the sugar dextrose, that forms the chief constituent of glucose, is composed of six atoms of carbon, twelve of hydrogen, and six of oxygen, C6H1206, or of six atoms of carbon and six elements of water. The carbohydrates include the starches,... | |

...— in practice it is very complicated. To begin with, grape-sugar is not a compact entity made up of six atoms of carbon, twelve of hydrogen and six of oxygen. On balance, there is that number of atoms to be found in one molecule of grape-sugar, but they are... | |

...classes : monosaccharids and disaccharids. The former have the formula C6H12O6, which means that one molecule is composed of six atoms of carbon, twelve of hydrogen and six of oxygen. The latter class have the formula C^H^Ou. The monosaccharids include dextrose, which is also known... | |
