Therefore, histidine is an amino acid that most often makes up the active sites of protein enzymes. As a result, they are often found clustered on the surface of globular proteins in aqueous solutions. Amino acid reactions Amino acids via their various chemical functionalities carboxyls, amino, and R groups can undergo numerous chemical reactions. However, two reactions peptide bond and cysteine oxidation are of particular importance because of their effect on protein structure.
At the turn of the 20th century, German chemist Emil Fischer first proposed this linking together of amino acids. Note that when individual amino acids are combined to form proteins, their carboxyl and amino groups are no longer able to act as acids or basessince they have reacted to form the peptide bond. Therefore, the acid-base properties of proteins are dependent upon the overall ionization characteristics of the individual R groups of the component amino acids. Amino acids joined by a series of peptide bonds are said to constitute a peptide.
After they are incorporated into a peptide, the individual amino acids are referred to as amino acid residues. Small polymers of amino acids fewer than 50 are called oligopeptides, while larger ones more than 50 are referred to as polypeptides.
Hence, a protein molecule is a polypeptide chain composed of many amino acid residues, with each residue joined to the next by a peptide bond. The lengths for different proteins range from a few dozen to thousands of amino acids, and each protein contains different relative proportions of the 20 standard amino acids.
Condensation reaction in which three molecules of the amino acid glycine produce a tripeptide chain, with the elimination of two molecules of water H2O. Cysteine oxidation The thiol sulfur-containing group of cysteine is highly reactive. The most common reaction of this group is a reversible oxidation that forms a disulfide. Oxidation of two molecules of cysteine forms cystinea molecule that contains a disulfide bond.
When two cysteine residues in a protein form such a bond, it is referred to as a disulfide bridge. Disulfide bridges are a common mechanism used in nature to stabilize many proteins.
Such disulfide bridges are often found among extracellular proteins that are secreted from cells. In eukaryotic organisms, formation of disulfide bridges occurs within the organelle called the endoplasmic reticulum. In extracellular fluids such as bloodthe sulfhydryl groups of cysteine are rapidly oxidized to form cystine.
In a genetic disorder known as cystinuriathere is a defect that results in excessive excretion of cystine into the urine.

The stones may cause intense pain, infection, and blood in the urine. Medical intervention often involves the administration of d-penicillamine. Penicillamine works by forming a complex with cystine; this complex is 50 times more water -soluble than cystine alone. In summary, it is the sequence of amino acids that determines the shape and biological function of a protein as well as its physical and chemical properties.

Thus, the functional diversity of proteins arises because proteins are polymers of 20 different kinds of amino acids. With 20 different amino acids to chose from at each of these 51 positions, a total ofor aboutdifferent proteins could theoretically be made. Other functions Amino acids are precursors of a variety of complex nitrogen -containing molecules.
Furthermore, there are complex amino-acid derived cofactors such as heme and chlorophyll. Heme is the iron -containing organic group required for the biological activity of vitally important proteins such as the oxygen -carrying hemoglobin and the electron -transporting cytochrome c.
Chlorophyll is a pigment required for photosynthesis. Portion of polynucleotide chain of deoxyribonucleic acid DNA. The inset shows the corresponding pentose sugar and pyrimidine base in ribonucleic acid RNA. Thyroxine a tyrosine derivative produced in the thyroid gland of animals and indole acetic acid a tryptophan derivative found in plants are two examples of hormones.
Several standard and nonstandard amino acids often are vital metabolic intermediates. Important examples of this are the amino acids argininecitrulline, and ornithine, which are all components of the urea cycle.
The synthesis of urea is the principal mechanism for the removal of nitrogenous waste. The most abundant protein by mass in vertebrates is collagen. Significant proportions of the amino acids in collagen are modified forms of proline and lysine: Genes are made up of promoter regions and alternating regions of introns noncoding sequences and exons coding sequences.

The production of a functional protein involves the transcription of the gene from DNA into RNA, the removal of introns and splicing together of exons, the translation of the spliced RNA sequences into a chain of amino acids, and the posttranslational modification of the protein molecule. Arguably, the most important posttranslational modification of amino acids in eukaryotic organisms including humans is the reversible addition of a phosphate molecule to the hydroxyl portion of the R groups of serinethreonineand tyrosine.
This event is known as phosphorylation and is used to regulate the activity of proteins in their minute-to-minute functioning in the cell. Serine is the most commonly phosphorylated residue in proteins, threonine is second, and tyrosine is third.
Proteins with carbohydrates sugars covalently attached to them are called glycoproteins. Glycoproteins are widely distributed in nature and provide the spectrum of functions already discussed for unmodified proteins. The sugar groups in glycoproteins are attached to amino acids through either oxygen O-linked sugars or nitrogen atoms N-linked sugars in the amino acid residues.
The O-linked sugars are attached to proteins through the oxygen atoms in serine, threonine, hydroxylysine, or hydroxylproline residues. The N-linked sugars are attached to proteins through the nitrogen atom in asparagine. Finally, there is the case of selenocysteine. Although it is part of only a few known proteins, there is a sound scientific reason to consider this the 21st amino acid because it is in fact introduced during protein biosynthesis rather than created by a posttranslational modification.
Selenocysteine is actually derived from the amino acid serine in a very complicated fashionand it contains selenium instead of the sulfur of cysteine. Analysis of amino acid mixtures The modern biochemist has a wide array of methods available for the separation and analysis of amino acids and proteins. These methods exploit the chemical differences of amino acids and in particular their ionization and solubility behaviour.
A typical determination of the amino acid composition of proteins involves three basic steps: Hydrolysis of the protein to its constituent amino acids. Separation of the amino acids in the mixture. Quantification of the individual amino acids. These conditions cleave the peptide bond between each and every amino acid residue.
The hydrolyzed protein sample is then separated into its constituent amino acids. Methods important for amino acid separations include ion exchange chromatography, gas chromatographyhigh-performance liquid chromatography, and most recently, capillary zone electrophoresis.
The sensitivity of the analysis of separated amino acids has been greatly improved by the use of fluorescent molecules that are attached to the amino acids, followed by their subsequent detection using fluorescence spectroscopy. Some common uses The industrial production of amino acids is an important worldwide business.
The first report of the commercial production of an amino acid was in It was then that the flavouring agent monosodium glutamate MSG was prepared from a type of large seaweed. This led to the commercial production of MSG, which is now produced using a bacterial fermentation process with starch and molasses as carbon sources.
Glycinecysteineand d,l- alanine are also used as food additives, and mixtures of amino acids serve as flavour enhancers in the food industry. The amino acid balance of soy or corn protein for animal feed is significantly enhanced upon the addition of the nutritionally limiting amino acids methionine and lysine.
Sage Ross Amino acids are used therapeutically for nutritional and pharmaceutical purposes. For example, patients are often infused with amino acids to supply these nutrients before and after surgical procedures.
