Unusual Amino Acids in Medicinal Chemistry.

Journal of Medicinal Chemistry, 2016
Unusual amino acids are fundamental building blocks of modern medicinal chemistry. The combination of readily functionalized amine and carboxyl groups attached to a chiral central core along with one or two potentially diverse side chains provides a ...

Regulation of amino acid transporters by amino acid availability

Current Opinion in Clinical Nutrition and Metabolic Care, 2001
There is growing recognition that amino acid availability has profound effects on many aspects of cell function, including the control of membrane transport mechanisms, cell signalling, and gene expression. The precise mechanisms by which amino acids are able to elicit control over such diverse processes have become the focus of intense investigation ...

Solid phase peptide synthesis utilizing 9-fluorenylmethoxycarbonyl amino acids.

International journal of peptide & protein research, 2009
9-Fluorenylmethoxycarbonyl (Fmoc) amino acids were first used for solid phase peptide synthesis a little more than a decade ago. Since that time, Fmoc solid phase peptide synthesis methodology has been greatly enhanced by the introduction of a variety of

Amino Acids and Proteins

2014
Amino acids and protein are key factors for growth. The neonatal period requires the highest intake in life to meet the demands. Those demands include amino acids for growth, but proteins and amino acids also function as signalling molecules and function as neurotransmitters.

A production of amino acids under possible primitive earth conditions.

Science, 1953
atmosphere of methane, ammonia, water, and hydrogen instead of carbon dioxide, nitrogen, oxygen, and water was suggested by Oparin (1) and has been-given emphasis recently by Urey (2) and Bernal (3).

Chromatography of amino acids on sulfonated polystyrene resins.

Journal of Biological Chemistry, 1951
The quantitative separation of amino acids by chromatography on columns of starch has sheen described in previous publications (l-3). In extending these investigations, a systematic study has been made of the separations of amino acids by elution ...

Amino Acids

1965
Publisher Summary Proteins are essential components of all living cells. During hydrolysis, proteins break down to amino acids, while in the organism, they are built up from amino acids. The simplest amino acid is glycine, H2N—CH2—COOH. Glycine is the only amino acid without a carbon-containing substituent, R, on the α-carbon.

Amino Acids and Respiration

Annals of Internal Medicine, 1983
Parenteral nutrition containing glucose and amino acids may stimulate respiration. To ascertain the effects of these solutions on respiration, eight normal subjects received an infusion of 5% dextrose (100 mL/h) for 7 days followed by an infusion of 3.5% amino acids (125 mL/h) for 24 hours.
