What is it and what does it do to the Body?

Histidine

Histidine, the only form involved in protein synthesis, is required for normal functioning in humans. It is an essential amino acid that the human body synthesizes from other compounds to satisfy the physiological needs of the body and is obtained through nutrition. Historically, histidine has been considered indispensable in adult diets, although it can persist for some time in some diets. Today, it is generally considered indispensable for adults, but not for children. Sources: 2

If you have enough protein in your diet, you may forget that you need this amino acid, but if your body can produce histidine, there is no deficiency in the amino acids. Sources: 6

Although histidine supplementation is thought to have the potential to benefit various diseases such as rheumatoid arthritis, there is not enough medical research data to support many of these claims. Although many medical sources report that histidine is considered safe, the use of a single amino acid can lead to a negative nitrogen balance. It is important to consult with a professional health care provider before taking histamine or other dietary supplements, as taking high doses could harm your healthSources: 6

Note: If you do not have sufficient protein intake, a single amino acid supplement is not recommended. The intake of histidine in combination with other dietary supplements such as calcium, iron or magnesium can lead to health complications. Sources: 6

The basic nitrogen atoms of histidine are involved in chemical reactions and can also act as electron pair donors. The fact that it is easily ionized in the body within the physiological The pH range makes it an ideal candidate for the reaction – catalyzing enzymes, as the protonated form can serve as a general acid, while the deprotonate forms can serve as a general base (see Figure 1). Sources: 3

The fact that histamine is vasoactive and increases the diameter of blood vessels improves blood circulation and raises blood pressure. Sources: 3

First, nitrogen is used in the histidine side chain to capture protons, which can then form other molecules as the proton oscillates away and the inactive enzyme regenerates. This enables the enzyme to become active by opening a site that allows the molecule to bind and be used for this purpose. Histidine is remarkable in that it has a ring structure in that there is an “R” group containing two groups of nitrogen. Sources: 1

Since it is positively charged, histidine can capture protons during embedding, and imidazole itself has been shown to act as a catalyst for reactions with RNA molecules, which could be useful for the production of RNA and the formation of other molecules such as nucleic acids. The reaction mechanism of ribozyme is a catalytic cytosine in which a proton is accepted by the catalytic cytOSin by attacking the 2-hydroxyl group. Sources: 0, 1

We also investigated the role of histidine in the production of ribozyme, which contains a 2-hydroxyl group, and its role as a catalytic cytosine catalyst. Sources: 0

In the catalytic triad, the base nitrogen histidine is used to abstract protons from serine, threonine and cysteine to activate them as nucleophiles. This is done by abstracting the proton by producing a positively charged intermediate, which can then be used as a molecular buffer to extract the proton from its acidic nitrogen. Histin uses its proon shuttle to quickly bring the proteins to a water molecule that binds to zinc and regenerates them into the active form of the enzyme. In this way, it is used in the production of Ribozyme by transporting a proton to the zinc-bound water molecules with its proton shuttles, thereby rapidly regenerating the active form of these enzymes. Sources: 4, 5

In the catalytic triad, alkaline nitrogen histidine is used to abstract protons from serine, threonine, and cysteine to activate them as nucleophiles, since these three amino acid components occur in the active sites of certain protease enzymes. This is done by abstracting the proton by producing a positively charged intermediate, which can then be used as a molecular buffer to extract the proton from its acidic nitrogen. In this way, histin uses its proon shuttle to quickly bring the proteins to a water molecule that binds to zinc and regenerates them into an active form of the enzyme. Histidine does this with its proton shuttle, which it uses to transport a proton to the zinc-bound water molecules and thus quickly regenerate it into the active form of an enzyme, in this case ribozyme. Sources: 2, 4

In his evolutionary biochemical approach, White suggested that histidine is indeed an ancient catalytic nucleotide that is part of the RNA world. True, White (32) stresses that it is an important component of RNA and a key component in the synthesis of proteins and nucleotides.
