    Amino Acids and Proteins

    D-Threonine

    (632-20-2)
    A steroisomer of the proteinogenic amino acid L-threonine.D-threonine is an important organic chiral source, mainly used in the fields of chiral drugs, chiral additives, chiral auxiliaries, etc., as a chiral source for chiral synthesis in the pharmaceutical industry. As an optically active organic acid, it has an irreplaceable role in the asymmetric synthesis of certain chiral compounds. It is mainly used to produce new broad-spectrum antibiotics, D-threonine, and threonine protection in peptide synthesis. Agent.

    D(-)-Arginine

    (157-06-2)
    Arginine (abbreviated as Arg or R) encoded by the codons CGU, CGC, CGA, CGG, AGA, and AGG is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain of a 3-carbon aliphatic straight chain capped by a complex guanidinium, classifying it as a charged (at physiological pH), aliphatic amino acid. Arginine is classified as a semiessential or conditionally essential amino acid, depending on the developmental stage and health status of the individual. Preterm infants are unable to synthesize or create arginine internally, making the amino acid nutritionally essential for them. Most healthy people do not need to supplement with arginine because their body produces sufficient amounts. Arginine was first isolated from a lupin seedling extract in 1886 by the German chemist Ernst Schultze.

    Protein is the material basis of life. Without protein, there is no life. Every cell and all important components in the body have proteins involved. Amino acid (Aminoacid) is the basic unit that constitutes a protein, giving a specific molecular structure to the protein, so that his molecules have biochemical activity. Proteins are important active molecules in organisms, including enzymes and enzymes that catalyze metabolism. Different amino acids are chemically polymerized into peptides, the original fragments of a protein, which are precursors for protein production. The basic unit of protein is amino acids, which form peptide chains through dehydration and condensation. A protein is a biological macromolecule composed of one or more polypeptide chains. Each polypeptide chain has 20 to hundreds of amino acid residues; various amino acid residues are arranged in a certain order. The organelles that produce proteins are ribosomes.
