The reaction is induced by dehydrating reagents. For example, 2-methyl-cyclohexan-1-ol dehydrates to 1-methylcyclohexene in the presence of Martin's sulfurane, which reacts irreversibly with water. [6] [7] Double dehydration is illustrated by the conversion of glycerol to acrolein: [8] [9]
Within the body, water is classified as intracellular fluid or extracellular fluid. Intracellular fluid refers to water that is contained within the cells. This consists of approximately 57% of the total body water weight. [19] Fluid inside the cells has high concentrations of potassium, magnesium, phosphate, and proteins. [21]
As the osmolyte concentration in fish cells scales linearly with pressure and therefore depth, osmolytes have been used to calculate the maximum depth where a fish can survive. Fish cells reach a maximum concentration of osmolytes at depths of approximately 26,900 feet (8,200 meters), with no fish ever being observed beyond 27,349 feet (8,336 ...
The increase in interstitial fluid solute concentration causes water to migrate from the cells of the body, through their membranes, to the extracellular compartment, by osmosis, thus causing cellular dehydration. [1] Clusters of cells (osmoreceptors) in the organum vasculosum of the lamina terminalis (OVLT) and subfornical organ (SFO), which ...
The recommended daily amount of drinking water for humans varies. [1] It depends on activity, age, health, and environment.In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for females over 18; it assumes about 80% from drink and 20 ...
1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C 4 H 9 OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer.
The proportion of cells within a sample which are undergoing mitosis at the time of observation, typically expressed as a percentage or as a value between 0 and 1. The number of cells dividing by mitosis at any given time can vary widely depending on organism, tissue, developmental stage, and culture media, among other factors. [2] mitotic ...
tert-Butyl alcohol is used as a solvent, ethanol denaturant, paint remover ingredient, and gasoline octane booster and oxygenate.It is a chemical intermediate used to produce methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) by reaction with methanol and ethanol, respectively, and tert-butyl hydroperoxide (TBHP) by reaction with hydrogen peroxide.
