Soap-Making Manual A Practical Handbook on the Raw Materials, Their Manipulation, Analysis and Control in the Modern Soap Plant. But when many difficultly oxidizable substances, such as chloral, camphor, turpentine oil, aniline, etc., are introduced into the body, the organism has the power of combining these with glucose to form glucosides. The Chemistry of Plant Life But considerable progress has been made in smelting highly sulphuretted ores by the heat of their own oxidizable constituents.

Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 6 "Cockaigne" to "Columbus, Christopher" For if the oxidizable miasma are destroyed by atmospheric ozone, they, in turn, cause the latter to disappear, and we have seen that it is itself a miasm. Chambers's Edinburgh Journal, No. 455 Volume 18, New Series, September 18, 1852 Finally, it may be assumed that easily oxidizable substances, such as aldehydes and acids, are possibly protected against too rapid, or premature, oxidation by being transformed into glucosides. The Chemistry of Plant Life When the gold is alloyed with easily oxidizable metals, such as copper or lead, it may be refined by cupellation. An Elementary Study of Chemistry These substances are the fats and oils of various kinds, less powerful sources of energy than the proteins, but they contain more potential energy than the carbohydrates because they are more oxidizable. The Doctrine of Evolution Its Basis and Its Scope By bringing any oxidizable substance into this portion of the flame, it oxidizes very quickly in consequence of the high temperature and the free access of air. A System of Instruction in the Practical Use of the Blowpipe Being A Graduated Course Of Analysis For The Use Of Students And All Those Engaged In The Examination Of Metallic Combinations This is doubtless the reason why ozone does not accumulate in the atmosphere in greater proportion than the oxidizable miasma, notwithstanding the constant formation of one and the other. Chambers's Edinburgh Journal, No. 455 Volume 18, New Series, September 18, 1852 A change toward acidity in protoplasm immediately results in the stimulating of carbohydrate-splitting enzymes, which increases the supply of easily oxidizable simple carbohydrates, thereby tending to compensate for the decrease in respiratory activity. The Chemistry of Plant Life He believes the hydrocarbons exert a direct influence only; being more oxidizable than fats, they guard the latter from oxidation. Scientific American Supplement, No. 821, September 26, 1891 It is, in general, true that oxidizable substances are determined by !direct! titration, while oxidizing substances are determined by !indirect! titration. An Introductory Course of Quantitative Chemical Analysis With Explanatory Notes They are not volatile, nor are they oxidizable.
