Each volume of this Specialist Periodical Report opens with an overview of amino acids and their applications. This is to facilitate the monitoring of the covered area and their potential expansion with the inclusion of other specialist reports in subsequent volumes. All chapters are compiled by leading researchers in their subject areas, which presents this series as an appealing source of information for the research community in both academia and industry.

Basic Structure of Amino Acids. Introduction Essential amino acids Why learn this? Amino acids play central roles both as building blocks of proteins and as intermediates in metabolism. The 20 amino acids that are found within proteins convey a vast array of chemical versatility. The precise amino acid content, and the sequence of those amino acids, of a specific protein, is determined by the sequence of the bases in the gene that encodes that protein.

Amino acids are organic compounds that contain amino —NH 2 and carboxyl —COOH functional groups , along with a side chain R group specific to each amino acid. About naturally occurring amino acids are known as of though only 20 appear in the genetic code and can be classified in many ways. In the form of proteins , amino acid residues form the second-largest component water is the largest of human muscles and other tissues. In biochemistry , amino acids which have the amine group attached to the alpha- carbon atom next to the carboxyl group have particular importance. They include the 22 proteinogenic "protein-building" amino acids, [6] [7] [8] which combine into peptide chains "polypeptides" to form the building blocks of a vast array of proteins. Twenty of the proteinogenic amino acids are encoded directly by triplet codons in the genetic code and are known as "standard" amino acids.

This new book is a monograph on the biochemistry of most proteins and all the amino acids. It consists of a compilation of 13 chapters contributed by 18 experts, including the editor, and summarizes early and recent developments in this field as an aid to evaluation of the properties and functions of proteins by students and investigators. Chemical and physical methods employed for the determination of the characteristics of proteins receive the major emphasis.

Proteinogenic amino acids are amino acids that are incorporated biosynthetically into proteins during translation. The word "proteinogenic" means "protein creating". Throughout known life , there are 22 genetically encoded proteinogenic amino acids, 20 in the standard genetic code and an additional 2 that can be incorporated by special translation mechanisms. In contrast, non-proteinogenic amino acids are amino acids that are either not incorporated into proteins like GABA , L -DOPA , or triiodothyronine , misincorporated in place of a genetically encoded amino acid, or not produced directly and in isolation by standard cellular machinery like hydroxyproline. The latter often results from post-translational modification of proteins. Some non-proteinogenic amino acids are incorporated into nonribosomal peptides which are synthesized by non-ribosomal peptide synthetases. Both eukaryotes and prokaryotes can incorporate selenocysteine into their proteins via a nucleotide sequence known as a SECIS element , which directs the cell to translate a nearby UGA codon as selenocysteine UGA is normally a stop codon.

 Мистер Беккер! - послышался голос.  - Мы на месте. Беккер встал и потянулся. Открыв полку над головой, он вспомнил, что багажа у него. Времени на сборы ему не дали, да какая разница: ему же обещали, что путешествие будет недолгим - туда и обратно. Двигатели снизили обороты, и самолет с залитого солнцем летного поля въехал в пустой ангар напротив главного терминала.

 Верно! - сказал Беккер с экрана.  - Может быть, у этих элементов разное число протонов или чего-то. Если вычесть… - Он прав, - сказал Джабба, повернувшись к Соши.  - На этих таблицах есть числа. Количество протонов.
