Glutaraldehyde is an organic compound with the formula (CH 2) 3 (CHO) 2.The molecule consists of a five carbon chain doubly terminated with formyl (CHO) groups. It is usually used as a solution in water, and such solutions exists as a collection of hydrates, cyclic derivatives, and condensation products, several of which interconvert.
Schiff bases have been investigated in relation to a wide range of contexts, including antimicrobial, antiviral and anticancer activity. They have also been considered for the inhibition of amyloid-β aggregation.
It operates similarly to formaldehyde, causing the deformation of proteins' α-helices. However glutaraldehyde is a larger molecule than formaldehyde, and so permeates membranes more slowly. Consequently, glutaraldehyde fixation on thicker tissue samples can be difficult; this can be troubleshot by reducing the size of the tissue sample.
Formaldehyde or glutaraldehyde fixes tissue or cells by irreversibly connecting a primary amine group in a protein molecule with a nearby nitrogen in a protein or DNA molecule through a -CH 2 - linkage called a Schiff base. The end result also creates the simulation, via color changes, of the appearance of blood flowing under the skin.
Textbook of Biochemistry is divided into the following chapters: [2] Introduction; Introduction to the concept of biochemistry, and a review of catalytic reactions and pH. Food-Stuffs, Their Derivatives and Related Substances. Ideas regarding carbohydrates, lipids, and proteins. The Chemistry of Digestion, the Circulation, and the Excreto.

Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
Biochemistry is a common university textbook used for teaching of biochemistry. It was initially written by Lubert Stryer and published by W. H. Freeman in 1975. [1] [2] [3] It has been published in regular editions since. [4] [5] [6] It is commonly used as an undergraduate teaching textbook or reference work. [7] [8]
