Amino acids, the primary component of proteins, are not stored in the human body, unlike carbohydrates and fats. The (free) amino acid pool is estimated to be only ~100 g in comparison with the amount of proteins (~12 kg) in a 70 kg person. Therefore, amino acids must be obtained from the diet, synthesized de novo (as are the eleven non-essential amino acids), or supplied from endogenous protein degradation. Amino acids can then be used for protein synthesis, the conversion to various nitrogen-containing essential biomolecules including neurotransmitters, purines and pyrimidines, porphyrins, creatine, and gaseous transmitters (NO, CO, and H2S), as well as an energy source. Six decades have passed since the identification of inborn errors in amino acid metabolism such as phenylketonuria, maple syrup disease, and homocystinuria. Thereafter, a growing body of evidence is accumulating to show the involvement of dysregulated amino acid metabolism in various aspects of common acquired disease conditions such as cardiovascular diseases, oncogenesis/tumor progression/metastasis, inflammation/autoimmune diseases, and metabolic syndrome. The Special Issue, “Amino Acid Metabolism and Regulation in Health and Disease”, of the International Journal of Molecular Sciences will include a selection of original research papers and reviews on the molecular and cellular biology of amino acids, including recently discovered fundamental aspects of regulation by bioactive amino acids (mTOR signaling and autophagy, sensing of amino acids by aminoacyl-tRNA synthetases), their metabolites (NO, H2S, homocysteine, and glutathione), and post-translational protein modification (S-nitrosylation, S-sulfhydration, S-glutathionylation, S- and N-homocysteinylation, and lysine residue aminoacylation), and their roles in health and disease.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
