There are three types of reactions postulated for the reaction between tannins (or rather Tannic acid) and proteins. 1. Tannic acid forms chemical bonds with basic amino acids in the protein chain. For example it bonds with the amino acid arginine at a pH 0f 3.5 where as it bonds with lysine at pH 7.5 when the tannic acid concentration is 2.5% 2. If the concentration of tannic acid is low (0.01% or 0.06 mM), only electrostatic interactions occur at pH7.5 resulting in the precipitation of proteins. 3. Hydrogen bonding is another mechanism by which tannins react with proteins if heavy metal are present. Google books on electron microscopy discusses these reaction and specific conditions in detail. I just did it by searching Google using the Key words "Tannin", "protein" and "reactions"
The type of reaction by which proteins are synthesized is dehydration synthesis. This process forms peptide bonds between the amino acids.
Muscadines contain high levels of tannins, which are natural compounds found in plants that give them a bitter taste. When we eat muscadines, the tannins can cause a reaction in some people's lips, resulting in an itchy or tingling sensation. This is because the tannins bind to proteins in our saliva and skin, causing them to dry out and become irritated. However, not everyone experiences this reaction, as some people may have a higher tolerance for tannins.

Aloe vera leaves are fleshy and act as storage tissue. It contains carbohydrates, proteins, tannins and variety of acids.
The proteins that control reaction in a cell are enzymes.

Enzymes are proteins which speed up chemical reactions.
A reaction that is used to build carbohydrates, lipids, and proteins is dehydration synthesis. Dehydration is the process of taking water out of something.
Compliment proteins are proteins found in the blood that fight off infections and diseases. They are produced by predecessor proteins, and are called "compliment" proteins because they participate in a compliment reaction.
