Three main categories of processes are used for the synthesis of peptides chemical synthesis, extraction from natural substances, and biosynthesis. On further scrutiny, almost 10 distinct synthetic methods can be distinguished (see Table 4.2). For the synthesis of some peptides, more than one method is used, including chemical (solution or solid phase) synthesis and recombinant biotechnology for salmon calcitonin, extraction from pancreas, semisynthesis, and recombinant biotechnology for insulin.

As stated earlier, the most important applications of chemical and metallurgical thermodynamics are in the processes of synthesis, extraction, refining, etc. The free energy change is by far the most important of the thermodynamic properties as it is linked to identifying the limits of an actual process. The free energy in turn is dependent on other parameters like activity, interaction co-efficient, entropy, enthalpy, heat capacity, etc.

Electrochemistry is the core science upon which many of these electrically oriented advances of the next few decades will depend for their practical execution (see Fig. 1.15). It underlies electrically powered synthesis, extractions (including fresh from brackish water), machining, stabilization of materials, storage of energy in the form of electricity, efficient conversion to electricity of the remaining fossil fuels, and... 

The symbol pr in printed CA Chemical Subject Indexes denotes preparation, and was first introduced in July-December 1994 (Volume 121). Abstracts are assigned pr on an intellectual basis by CAS document analysts if the original source material provides information on preparation or related concepts such as manufacture, purification, recovery, synthesis, extraction, generation, isolation, and secretion.

One or several active compounds (DS) are prepared by organic synthesis, extracted from vegetable, animals, micro-organisms or obtained by biotechnology. The DS is generally associated in the product with several excipients of chemical, mineral or biological in nature either as monomers or as polymers. 

Amino acids have been produced by chemical synthesis, extraction from protein hydrolysates, enzymatic synthesis, and microbial fermentation. The chemical synthesis includes artificial synthesis from chemical starting material and usually produces an enantiomeric mixture of amino acids which will further require a step of optical resolution. Only a few amino acids are produced economically by chemical synthesis owing to the high production cost. Glycine and methionine are the two amino acids that are manufactured chemically and widely used in animal feeds. Glycine is manufactured from ammonia and formaldehyde and does not have a stereo chemical center or is achiral. For methionine, animals have a d-amino acid oxidase and transaminase activity that can convert the D form to L form of the amino acid. Otherwise DL methionine is acetylated to produce L-methionine.
