Protein coagulants

Non-sulfonated lignins find utility as emulsifiers and stabilizers in water-based asphalt emulsions, as coreactants in phenolic binder applications, as negative plate expanders in lead acid storage batteries, as protein coagulants in fat rendering, and as flocculants in waste water systems. 

Chemical injury may occur when a living cell comes into contact with a chemical foreign to its system. Chemicals which enter the living organism which are foreign to the system are known as xenobiotics. Chemical injury may be external as a relatively non-selective process wherein an overall disruption takes plase. An example of this would be an acid burn on the surface of the skin, wherein a general protein coagulation takes place with tissue and cellular disruption. The process of absorption is not specifically involved in this type of chemical injury. 

Eugenol, like other phenolic compounds, is a structurally non-specific drug. The pharmacological action is not directly subordinated to chemical structure, except to the extent that structure affects physicochemical properties, as adsorption, solubility, pKa, and oxidation-reduction potential, factors which influence permeability, depolarization of the membrane and protein coagulation [34],... 

The stomach environment is acidic as a result of HC1 secretion by the parietal cells. The acidic pH serves to denature many proteins, thus making them susceptible to proteolysis. The chief cells of the stomach produce pepsinogen, which is activated to pepsin by the HC1 (see Table 20.3). The optimum pH of peptic activity is around 2, and pepsin is inactivated at neutrality. Another stomach enzyme is rennin or chymosin, which is present in infants but not in adults. It removes a glycopeptide from milk-K-casein, disrupting the casein micelle and promoting milk protein coagulation and digestion.

Interfacial films of protein coagulate under certain conditions, the properties of the coagulated protein being quite different from those of the original crystalline protein. F or example, solubility is lost. 

In applications to sausage products which are produced in cellulose casings, the coagulation of surface proteins is an essential functional effect of smoke solutions. While the above mentioned carbonyl-amine reaction is one of two mechanisms of surface modifications, the acidity of natural smoke flavourings is an even more valuable processing aid for meat surface protein coagulation. 

The content of bitter substances is closely related to the dosage of hop. The flavouring is steamed down to the desired concentration by cooking it for 70-120 min. The protein coagulates, different valuable hop components are diluted and the enzymes inactivated. 

A chemical peel is a skin treatment intended to visibly improve the structure of treated tissue by the external application of a caustic solution. It can simply accelerate the natural processes of exfoliation, but can also completely destroy the epidermis and a more or less large proportion of the dermis, essentially by protein coagulation or lysis. The effect of any peel reaches the dermis, directly or indirectly and to varying depths, where the processes of regeneration are induced to a greater or lesser degree, depending on the molecule or molecules used and the application procedure. 

The doctor should be ready to neutralize the peel at the least sign of protein coagulation (frosting). It is a good idea to alternate flashlamp treatment and EPS, as with the mesolift EPS one week and flashlamp the following week. 

Some TCA clay pastes are presented as causing simple erythema with no protein coagulation, but they nevertheless have a downtime of 6-8 days. ... 

Applying TCA causes protein coagulation more or less rapidly, depending on the formulation of the peel, its concentration, prior preparation of the skin, the pressure of...
