G. Metabolic Difference. Micro-organisms attack wood by secreting enzymes into the immediate structure which in turn break down the wood components into small, soluble units that become nutrients for the organism. The main destructive enzyme system the wood-rotters contain is a class of proteins known as cellulases. These enzymes break down he polymeric cellulose, the strong backbone of wood, into digestible units. Humans do not possess this enzyme system consequently, we cannot degrade cellulose-containing materials. 

Cell materials are either water-soluble or water-insoluble. The smaller building blocks of cells like amino acids and glucose are water-soluble, but the large molecules they eventually synthesize, like proteins, cell walls, fats and long-chain carbohydrates are water-insoluble. This is a subtle but significant fact. The water-soluble units can be carried around the body in aqueous solutions to sites where they are needed, but once a new larger molecules are synthesized then these are water-insoluble and so cannot be removed from the cell unless an enzyme or chemical attack takes place to break them up. 

The solubility unit "mole fraction" in the source table was misprinted and thus was corrected it to "mol%" based on Figure 4 in the same article. Synonym 4-Hydroxy-3-methoxybenzaldehyde Source Wells, P. A. Chaplin, R. P. Foster, N. R. J. Supercrit. Fluids (1990), 3(1), 8-14. 

Sometimes the fluid concentration is expressed in the units M, m, and N. M is an abbreviation of the solubility unit, molarity, which is the number of moles (or gram formula weights) of solute in one liter (L) of solution. The abbreviation m is another unit, molality, which is the number of moles (or gram formula weights) of solute in one kilogram of solvent. A molar concentration is labeled with a square bracket. The unit of N is meq/mL. The unit of... 

The solubility decreased as expected. The pressure on the solution was reduced from 4.0 atm to 1.0 atm, so the solubility should be reduced to one-fourth its original value, which it is. The unit g/L is a solubility unit, and there are two significant figures.

The basic physico-chemical properties of the fatty amine surfactants drive their utilities as adjuvants. Such molecules consist of a water-insoluble hydrophobic unit, in this case derived from tallow fatty acid. The water-soluble unit of the molecules consist of two chains of polymeric alkoxides, in these cases ethylene oxide and/or another alkylene oxide, such as propylene oxide. A nitrogen atom in the middle of the molecule connects the water-soluble and water-insoluble parts. Due to the electronic properties of nitrogen with respect to the carbon atom connectors which are usual in surfactants, the molecule has an overall cationic character, thus resulting in improved substantivity (adherence) to the leaf surface. 

Two measured solubilities will define the value of o that is specific to a sol-ute/cosolvent pair. The value of a is also dependent of the solubility unit selected and on whether 10-based or e-based logarithm is used. The magnitude of o reflects the difference in molecular interactions between solute/cosolvent and solute/water. When applied to describe cosolvency, a is like a microscopic partition coefficient if water and cosolvent are thought of as two independent entities. There had been other definitions of a, such as the... 

Other gas solubility units. Depending on the various applications, units such as volume fraction, concentration, molarity, molality and weight fraction have been used to express gas solubility in liquids. For example.
