In nature, the most common representatives are 2-amino acids (α-amino acids) with the general formula RCH(NH2)COOH. This chapter provides knowledge of amino acids. The main contents of this chapter include all of the following: structure and properties of amino acids, synthesis of amino acids: a combination of amine and carboxylic acidchemistry,...and other contents.

Trichloroisocyanuric acid synthesis process was studied by using DFT method. The obtained results demonstrate that the keto-enol isomerization of the cyanuric acid is a base-catalyzed reaction. It is possible that in the presence of NaOH the process of moving hydrogen in the cyanuric acid molecule and the reaction of neutralizing cyanuric acid can execute consecutively. And in this case NaOH plays the role as a donor of hydroxyl group catalyzing the movement of hydrogen and as neutralizing agent in an exothermal process.
Fatty acids are an important energy source, for they yield over twice as much energy as an equal mass of carbohydrate or protein. In humans, the primary dietary source of fatty acids is triacylglycerols. This lecture will describe the metabolism of fatty acids. The two main components of fatty acid metabolism are β oxidation and fatty acid synthesis. Upon completion of this lecture, you will understand that the fatty-acid breakdown reactions of β oxidation result in the formation of reduced cofactors and acetyl-CoA molecules, which can be further catabolized to release free energy.
This experiment aimed to synthesize isoamyl acetate and understand preparing ester’s mechanism. The test compounds underwent reflux, distillation, extraction and vacuum filtration. Through an acid, acetic acid could serve as a substrate. This could easily be attacked by isoamyl alcohol, thus producing isoamyl acetate.
Aspirin is an effective analgesic (pain reliever), antipyretic (fever reducer) and anti-inflammatory agent and is one of the most widely used non-prescription drugs. The use of aspirin had its origin in the 18th century, when it was found that an extract from the bark of willow trees was useful in reducing pain and fever. The active ingredient in willow bark was later found to be salicylic acid.

Tribasic lead sulfate Ž3BS. and tetrabasic lead sulfate Ž4BS., used as precursors of the positive active material in the leadracid batteries, were prepared by a new method: reactive grinding. The effects of various experimental parameters Žstoichiometry, hygrometry of the starting compounds, duration of mechanical treatment. upon the nature and morphological features of the resulting phase were investigated.
Two enzymes control the rearrangement of carbon skeletons which result in the production of Glyceraldehyde-3-phosphate and Fructose-6-phosphate.
Transketolase transfers C2 units: TPP requiring enzyme like pyruvate dehydrogenase
Transaldolase transfers C3 units: uses a shiffs base with an active lysine group
Phase-transfer-catalyzed alkylation of glycinate
Schiff base with racemic secondary alkyl
halides proceeded with excellent levels of synand
enantioselectivities under the influence of a
chiral quaternary ammonium bromide and 18-
crown-6. The alkylation product can be
selectively converted to the corresponding anti
isomer, allowing the preparation of all the
stereoisomers of β-alkyl-α-amino acid

Biotin is a water-soluble vitamin that plays a role in gene expression, gluconeogenesis, and fatty acid synthesis and serves as a CO 2 carrier on the surface of both cytosolic and mitochondrial carboxylase enzymes. The vitamin also functions in the catabolism of specific amino acids (e.g., leucine). Excellent food sources of biotin include organ meat such as liver or kidney, soy, beans, yeast, and egg yolks; however, egg white contains the protein avidin, which strongly binds the vitamin and reduces its bioavailability.
