D5LR (5% dextrose in lactated Ringer solution) D50 – 50% dextrose in water; The percentage is a mass concentration, so a 5% glucose/dextrose solution contains 50 g/L of glucose/dextrose (5 g per 100 ml). This usage is imprecise but widely used, as discussed at Mass concentration (chemistry) § Usage in biology. Glucose provides energy 4 kcal ...
Granulated sugar provides energy in the form of calories, but has no other nutritional value. In human nutrition, empty calories are those calories found in foods and beverages (including alcohol) [1] composed primarily or solely of calorie-rich macronutrients such as sugars and fats, but little or no micronutrients, fibre, or protein.
Hydrogels have a high water content, [7] with some hydrogels containing up to 90% water. [5] Active drugs and other substances dispersed as colloids or dissolved in water can be easily taken up by hydrogels. [5] Hydrogels are biocompatible. [5] [7] They also swell to a greater volume than organogels when in contact with water and other natural ...

Sweet-tasting, water-soluble carbohydrates This article is about the class of sweet-flavored substances used as food. For common table sugar, see Sucrose. For other uses, see Sugar (disambiguation). Sugars (clockwise from top-left): white refined, unrefined, brown, unprocessed cane Sugar ...
[45] [46] Dextrose monohydrate is composed of approximately 9.5% water by mass; through the process of dehydration, this water content is eliminated to yield anhydrous (dry) dextrose. [40] Anhydrous dextrose has the chemical formula C 6 H 12 O 6, without any water molecule attached which is the same as glucose. [38]
Triglyceride 3 NaOH / H 2 O Δ 3 × soap 3 × glycerol Triglycerides can be saponified with sodium hydroxide to give glycerol and fatty sodium salt or soap. Typical plant sources include soybeans or palm. Animal-derived tallow is another source. From 2000 to 2004, approximately 950,000 tons per year were produced in the United States and Europe; 350,000 tons of glycerol were produced in the U ...
These estimates are for a "reference woman" who is 1.63 m (5 ft 4 in) tall and weighs 57 kg (126 lb) and a "reference man" who is 1.78 m (5 ft 10 in) tall and weighs 70 kg (154 lb). [19] Because caloric requirements vary by height, activity, age, pregnancy status, and other factors, the USDA created the DRI Calculator for Healthcare ...
In water purification, chalcogels have shown promise in absorbing the heavy metal pollutants mercury, lead, and cadmium from water. [102] Aerogels may be used to separate oil from water, which could for example be used to respond to oil spills. [103] [80] [75] Aerogels may be used to disinfect water, killing bacteria. [104] [105]
