hydroxide in Biological Definition

Alcohol

... Na + Water is similar in pK a to many alcohols, so with sodium hydroxide there is an equilibrium set up which usually lies to the left: R-OH ... reaction ) in the presence of the halogen and a base such as sodium hydroxide . See also alcohol as a fuel alcoholic beverage ...

Cellulose

... is a straight chain (no coiling occurs). In microfibrils , the multiple hydroxide groups hydrogen bond with each other, holding the chains firmly together ... material, the portion that does not dissolve in a 17.5% solution of sodium hydroxide at 20 deg C. is Alpha Cellulose , which is true cellulose; the portion ...

Gel electrophoresis

... through the gel in a complicated manner based on their tertiary structure. Therefore, agents that disrupt the hydrogen bonds , such as sodium hydroxide or formamide , are used to renature the nucleic acids and cause them to behave as long rods again. Proteins, on the other hand, can have ...

Fehling's solution

... are mixed: 70 grams copper(II) sulfate pentahydrate 350 grams Rochelle salt (potassium sodium tartrate tetrahydrate) and 100 grams sodium hydroxide The cupric ion is complexed with the tartrate ion. Contact with an aldehyde group reduces it to a cuprous ion, which then precipitates as red ...

Hydrolysis

... In other hydrolysis reactions such as hydrolysing the peptide links of amino acids only one of the products, the carboxylic acid product, has a hydroxide group derived from the water. The amine product gains the remaining hydrogen ion. Hydrolysis can be considered as the opposite of condensation , ...
