- 1. Chemically, the addition of water; differentiated from hydrolysis, where the union with water is accompanied by a splitting of the original molecule and the water molecule. See also: solvation. 2. Clinically, the taking in of water; used commonly in the sense of reduced hydration or dehydration.

Hydration of fat-free body mass: review and critique of a classic body-composition constant The assumed “constancy” of fat-free body mass hydration is a cornerstone in the body-composition research field. Hydration, the observed ratio of total body water to fat-free body mass, is stable at ≈0.73 in mammals and this constancy provides a means of estimating total body fat in vivo.

Have A Headache? Does Your Little One Seem Tired Or Cranky? These Might Be Signs Of Dehydration. We lose water every day through natural bodily functions, but dehydration occurs when we lose more bodily fluids than we’re taking in. Because humans are made up of mostly water and electrolytes, we need to maintain the proper balance of these in our system. That means staying hydrated is important throughout the day.

Dehydration Water is a critical element of the body, and keeping the body adequately hydrated is a must to allow the body to function. Up to 75% of the body's weight is made up of water. Most of the water is found within the cells of the body (intracellular space).

Dehydration in Children Dehydration is a condition that can occur with excess loss of water and other body fluids. Dehydration results from decreased intake, increased output (renal, gastrointestinal or insensible losses), a shift of fluid (eg, ascites, effusions), or capillary leak of fluid (eg, burns and sepsis).

Dehydration Dehydration refers to a deficit of total body water, with an accompanying disruption of metabolic processes. Dehydration is also a cause for hypernatremia. The term dehydration is distinct from hypovolemia (loss of blood volume, particularly plasma). Dehydration occurs when free water loss exceeds free water intake, usually due to exercise or disease, but also due to high environmental temperature.

- Medically, dehydration is a serious and potentially life-threatening condition in which the body contains an insufficient volume of water for normal functioning. The term volume depletion is similar to dehydration, but it refers to the loss of salts as well as water.ehydration occurs when these losses are not replaced adequately and a deficit of water and electrolytes develops. The volume of fluid lost through the stools in 24 hours can vary from 5 ml/kg (near normal) to 200 ml/kg, or more. The concentrations and amounts of electrolytes lost also vary.

Hydrate The notation  hydrated compound ⋅nH2O , where n is the number of water molecules per formula unit of the salt, is commonly used to show that a salt is hydrated. The n is usually a low integer, though it is possible for fractional values to occur. For example, in a monohydrate n is one, and in a hexahydrate n is 6.

Water Intoxication: The Dangers Of Overhydration What Is Water Intoxication? Water intoxication (also known as overhydration or hyponatremia) is a physical condition that results from an abnormal balance of electrolytes in the body. When an overabundance of water causes an imbalance between water and electrolytes in the body, cells start to swell up.

- By definition, the enthalpy of hydration, #δ_hydH#, is the enthalpy change that takes place when 1 mol of gaseous ion is dissolved in excess water to make one mole of aqueous ion. Significance of hydration enthalpy. It gives an indication of the strength of the interaction of water molecules with the ions.

- Dehydration is an excessive loss of water from the body tissues, often accompanied by an imbalance of sodium, potassium, chloride, and other electrolytes. It can occur whenever fluids are lost and not adequately replaced, especially when an individual does not drink enough fluids.evere dehydration can cause more serious symptoms such as confusion, low blood pressure, shock, and may even lead to death. The human body consists of about 60-70% water and must have a continuous supply in order to function.

Water of Hydration Definition Definition: Water of hydration is water that is stoichiometrically bound into a crystal. Crystal salts containing water of hydration are called hydrates.Also Known As: water of crystallization, crystallization water.

- Dehydration. Hydration involves the addition of water to an unsaturated molecule. Dehydration is the reverse of hydration, and involves the removal of water from a molecule. The dehydration of an alcohol is an important way to make alkenes. Don't confuse hydration and dehydration with condensation and hydrolysis (see Making and breaking esters). 1  Page. 2  1. 3  2.

Hydration Thus hydration is one of the main causes of electrolytic dissociation in aqueous solutions. The formation of crystal hydrates and the hydration of molecules and ions in solutions are special cases of solvation, that is, the addition of the solvent molecule. Hydration also includes processes leading to the binding of water through absorption forces. In biological systems hydration involves the addition (binding) of water to various substrates in the organism. The water, which enters into the hydration shells formed on hydration, constitutes the principal quantity of the so-called bound water of a cell’s protoplasm. Many biological processes are connected with hydration.

Understanding The Importance Of Proper Hydration For Maximum Gains In And Out Of The Gym! Water is needed to transport nutrients to your cells and transport waste out of the body. Water helps form the structures of protein and glycogen. In order to move and flex your muscles, you need water. If your body is dehydrated, your muscles will be deprived of electrolytes and cramp.

hydrate Hydration definition, any of a class of compounds containing chemically combined water. In the case of some hydrates, as washing soda, Na 2 CO 3 ⋅10H 2 O, the water is loosely held and is easily lost on heating; in others, as sulfuric acid, SO 3 ⋅H 2 O, or H 2 SO 4 , it is strongly held as water of constitution. to combine chemically with water.

Hydrate In chemistry, a hydrate is a substance that contains water or its constituent elements. The chemical state of the water varies widely between different classes of hydrates, some of which were so labeled before their chemical structure was understood.he sugar trehalose, for example, exists in both an anhydrous form (melting point 203 °C) and as a dihydrate (melting point 97 °C). Protein crystals commonly have as much as 50% water content. Molecules are also labeled as hydrates for historical reasons not covered above.

Dehydration reaction For the removal of water from solvents and reagents, see Desiccation. In chemistry and the biological sciences, a dehydration reaction is usually defined as a chemical reaction that involves the loss of a water molecule from the reacting molecule. Dehydration reactions are a subset of condensation reactions. Because the hydroxyl group (–OH) is a poor leaving group, having a Brønsted acid catalyst often helps by protonating the hydroxyl group to give the better leaving group, –OH2+. The reverse of a dehydration reaction is a hydration reaction.

How does a hydrate differ from an anhydrate? For example, the Greek root hydra-means that it has to do with water; can be found in the words ''hydrate'' and ''anhydrate.'' Answer and Explanation: A hydrate is any substance that has been chemically combined with water. Hydrates can be heated so that the water will boil off. The completely waterless substance left at the end of the process is an anhydrate. So a hydrate contains water, and an anhydrate does not. Learn more about this topic:

- Hydrates are compounds that incorporate water molecules into their fundamental solid structure. In a hydrate (which usually has a specific crystalline form), a defined number of water molecules are associated with each formula unit of the primary material. Gypsum is a hydrate with two water molecules present for every formula unit of CaSO4.
