Since alcohol is absorbed into body water content, and men have more water in their bodies than women, for women there will be a higher blood alcohol concentration from the same amount of alcohol consumption. [21] Women are also thought to have less alcohol dehydrogenase (ADH) enzyme which is required to break down alcohol. [8]
ADH was also one of the first oligomeric enzymes that had its amino acid sequence and three-dimensional structure determined. [16] [17] [18] In early 1960, the alcohol dehydrogenase (ADH) gene was discovered in fruit flies of the genus Drosophila melanogaster. [19] Flies that are mutant for ADH cannot breakdown alcohols into aldehydes and ...
The activity of ADH and CYP2E1 alone does not appear sufficient to fully explain the increase in ethanol metabolism rate. There may be one or more additional pathways that metabolize as much as 25 to 35% of ethanol at typical concentrations. [3] A small amount of ethanol undergoes conjugation to form ethyl glucuronide and ethyl sulfate. [2]
Excessive ADH causes an inappropriate increase in the reabsorption in the kidneys of solute-free water ("free water"): excess water moves from the distal convoluted tubules (DCTs) and collecting tubules of the nephrons – via activation of aquaporins, the site of the ADH receptors – back into the circulation. This has two consequences.
Angiotensin II causes the release of anti-diuretic hormone (ADH), [6] also called vasopressin – ADH is made in the hypothalamus and released from the posterior pituitary gland. As its name suggests, it also exhibits vaso-constrictive properties, but its main course of action is to stimulate reabsorption of water in the kidneys.
A low serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma. Syndrome of inappropriate ADH secretion occurs when excessive release of antidiuretic hormone results in inappropriately elevated urine osmolality (>100 mOsmol/L) relative to the blood plasma, leading to hyponatraemia.
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 ...
