Biomolecules and Enzymes

Arginase is a manganese-containing enzyme. The reaction catalyzed by this enzyme is: arginine + H2O → ornithine + urea. It is the final enzyme of the urea cycle. It is ubiquitous to all domains of life.

The three-dimensional structure of the enzyme determines the appearance of the active site. The active site accommodates the shape of the biological substrate that requires transformation. They fit like a key in a lock. This is what makes enzymes specific in their actions. Only substances of the right shape will be transformed.

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. This enzyme participates in bile acid biosynthesis.

It provides resistance to our body and inhibits the growth of hair, nails etc.

Sulbutiamine is a synthetic derivative of thiamine (vitamin B₁). As a dimer of two modified thiamine molecules, it is a lipophilic compound that crosses the blood-brain barrier more readily than thiamine and increases the levels of thiamine and thiamine phosphate esters in the brain.

Tertiary structure is the final three-dimensional structure of a protein, which results from a large number of non-covalent interactions between amino acids.

Alanine is necessary for the maintainance of proper blood glucose level from dietary protein. It stimulates lymphocyte production and may help people who have immune suppression. It also strengthens the immune system by producing antibodies.

Isoleucine is necessary for the optimal growth of infants and for maintaining nitrogen balance in adults.

Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet. It is encoded in the standard genetic code as the codon UGG.

L-theanine reduces stress and anxiety without the tranquilizing effects found in many other calming supplements.

This option is correct because methionine amino acid is classified as non polar as it has a straight side chain that possesses a S-methyl thioether (i.e C-S-C bonding) at the gama-carbon. It is an essential amino acid in all metazoa. These are initiated by the polypeptide chain.

Arginine is an α-amino acid. At the level of molecular genetics, in the structure of the messenger ribonucleic acid mRNA, CGU, CGC, CGA, CGG, AGA, and AGG are the triplets of nucleotide bases or codons that code for arginine during protein synthesis.

Immunohistochemistry or IHC refers to the process of detecting antigens (e.g., proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues. IHC takes its name from the roots immuno, in reference to antibodies used in the procedure, and histo, meaning tissue (compare to immunocytochemistry).

Amino acids link together through peptide bonds to form proteins, making them the fundamental building blocks of all proteins. Fats are built from fatty acids and glycerol, vitamins are organic micronutrients, and sugars are carbohydrates - none of which are made from amino acids.

Antibodies may block the binding to target cell and would increase the rate of removal of toxin from the circulation by immune complex formation.
