Proteins

Glycosylation - Purpose
... The carbohydrate chains attached to the target proteins serve various functions ... For instance, some proteins do not fold correctly unless they are glycosylated first ... Also, polysaccharides linked at the amide nitrogen of asparagine in the protein confer stability on some secreted glycoproteins ...

Fluorescence Recovery After Photobleaching - Applications Outside The Membrane
... FRAP can also be used to monitor proteins outside the membrane ... After the protein of interest is made fluorescent, generally by expression as a GFP fusion protein, a confocal microscope is used to photobleach and ... kinetic coefficients, such as those for the protein's binding reactions and/or the protein's diffusion coefficient in the medium where it is being monitored ...

Food Allergy - Pathophysiology
... When immune cells encounter the allergenic protein, IgE antibodies are produced this is similar to the immune system's reaction to foreign pathogens ... The IgE antibodies identify the allergenic proteins as harmful and initiate the allergic reaction ... The harmful proteins are those that do not break down due to the strong bonds of the protein ...

Ergastic Substance - Proteins
... Although proteins are the main component of living protoplasm, proteins can occur as inactive, ergastic bodies—in an amorphous or crystalline (or crystalloid) form ... A well-known amorphous ergastic protein is gluten ...

Putrefaction - Description
... The breakdown of proteins in a decomposing carcass is a spontaneous process but one that is accelerated as the anaerobic microorganisms, already present in the ... As cells and their proteins are digested, the tissues of the body are left in a weakened state ... Proteins are broken down into smaller components and these are excreted by the bacteria ...
