metabolic water

water formed by a type of METABOLISM called CATABOLISM in which complex molecules are broken down to release their stored energy, with water as a by-product. In certain insects and desert mammals, which feed primarily on dry seeds, the water conservation mechanisms are so efficient that metabolic water alone is sufficient to replace the normal water loss; ‘free'water is not required in the diet.
