hydro-, hydra-, hydr-, hyd-
(Greek: water)
Organisms or creatures that spontaneously move away from moisture or wet conditions: There are some ahydrotaxes in nature that are intolerant of or can't exist very long in water or even in prolonged wet or damp environments.
An enzyme (protein manufactured by a living cell) that speeds up the rate of reduction or removal of water from a mixture: Jane and Heather were studying the comparative rates of anhydrides from different mixtures or compounds.
A lack of water in the system: After a long hike in the desert, Alfred appeared to be suffering from
anhydration and needed to drink lots of water.
A compound derived by the removal of water from an acid or other compound: During the chemistry lesson, Campbell and Joseph experimented with removing water from an acid mixture in order to create other anhydrides or new substances.
1. Dormancy induced by low humidity or by drying out: The seeds of many desert plants go into a state of anhydrobiosis when there is no rainfall for an extended period of time.
2. A state caused by dehydration, in which an organism's metabolism (rate of bodily function) is reduced to an imperceptible level: Dr. Sneed, the veterinarian, was very concerned about the extreme state of anhydrobioses in the dog that was brought into his office because its body processes were barely detectable.

1. A dread of consuming bad water or of being contaminated or infected in some way by it: Because of her cacohydrophobia, Evelyn always carried a bottle of juice with her in order to avoid drinking the impure liquid from a public fountain.
2. An abnormal fear of being exposed to water from the cloaca or waste pipes: Even though she enjoyed the walking tours of the large and ancient city, Lois would not go on the historical sewer walk because of her cacohydrophobia of the polluted liquid that was still there.

carbohydrate (s), carbohydrates (pl)
An organic compound present in the cells of all living organisms and a major organic nutrient for human beings; it consists of carbon, hydrogen, and oxygen, and makes up sugar, starch, and cellulose.
Carbohydrates are made up of carbon, hydrogen, and oxygen in a ratio of approximately one carbon, two hydrogen, and one oxygen.
Sugar, starch, and cellulose constitute the carbohydrates. Sugars are classified according to whether or not they can be decomposed in a water solution.
Simple sugars or monosaccarides cannot be so decomposed; complex sugars or polysaccarides can be broken down by water or hydrolysis. The most common simple sugars are glucose and fructose. See saccharo- for more details.
Glucose is also called dextrose, and fructose is also known as levulose. The common white commercial sugar is sucrose, which is a disaccharide or double sugar; a combination, actually, of a glucose and a fructose molecule.
cryohydrate
1. A mixture of ice and a salt combined in a proportion designed to have the lowest possible melting point.
2. A eutectic mixture, especially one having water as one of its constituents.
2. A eutectic mixture, especially one having water as one of its constituents.
An enzyme (protein) that modifies the removal of the elements of water from material or substances on which an enzyme acts: "A dehydrase catalyzes (modifies) the removal of oxygen and hydrogen from metabolites (specific substances within living bodies) in proportion to which they form water."
dehydrate (verb), dehydrates; dehydrated; dehydrating
1. To remove water from; to make anhydrous.
2. To remove moisture from food as a way of preserving it (vegetables, for example).
3. To deplete the bodily fluids of: The hot weather dehydrated some of the runners so much, that several of them had to quit.
4. To lose water or bodily fluids.
