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 ...
Maltodextrins are classified by a dextrose equivalent (DE), [5] [6] a number between 3 and 20 that corresponds to the number of free chain ends in a certain sample. A lower DE value means the polymer chains are longer (contain more glucose units) whereas a higher DE value means the chains are shorter. [6]

Graph depicting blood sugar change during a day with three meals. The glycemic (glycaemic) index (GI; / ɡ l aɪ ˈ s iː m ɪ k / [1]) is a number from 0 to 100 assigned to a food, with pure glucose arbitrarily given the value of 100, which represents the relative rise in the blood glucose level two hours after consuming that food.

[5] [3] The gelators may precipitate and salt out, and some drugs may degrade in gel formulation due to the other ingredients present in the formulation. [ 5 ] Some additives and gelators added into the formulation may cause irritation problems, [ 5 ] [ 8 ] such as skin irritation, dermatitis or allergic conditions . [ 2 ]
Glucose (dextrose) has a molecular mass of 180, while water has a molecular mass of 18. For each 2 glucose monomers binding, a water molecule is removed. Therefore, the molecular mass of a glucose polymer can be calculated by using the formula (180*n - 18*(n-1)) with n the DP (degree of polymerisation) of the glucose polymer.
Proteins and most carbohydrates have about 17 kJ/g (4 kcal/g), though there are differences between different kinds. For example, the values for glucose, sucrose, and starch are 15.57, 16.48 and 17.48 kilojoules per gram (3.72, 3.94 and 4.18 kcal/g) respectively.
Purification of the three types of cyclodextrins takes advantage of the different water solubility of the molecules: β-CD which is poorly water-soluble (18.5 g/L or 16.3 mM at 25 °C) can be easily retrieved through crystallization while the more soluble α- and γ-CDs (145 and 232 g/L respectively) are usually purified by means of expensive ...
