Arginine, glycine and aspartic acid

The use of electroactive molecules to release cells was demonstrated by Yeo et al. [3] with the RGD peptide and fibroblast cells. The RGD peptide, which consists of three amino acids, arginine, glycine, and aspartic acid, linked together, is a ligand that binds to many different types of cells. Yeo et al. created a monolayer of... 

The Silurian Wills Creek, Tonoloway and Keyser Formations were tested for residual amino acids (Table V). The following were found cystine( ), histidine(P), arginine, glycine(P), aspartic acid(P), glutamic acid(P), threonine, alanine, valine, leucine. 

As early as 1905 Abderhalden (Al) isolated from the hydrolyzate of the nondiffusible fraction of human urine four amino acids, i.e., leucine, alanine, glycine, and glutamic acid, and detected two others phenylalanine and aspartic acid. Some amino acids derived from this fraction have been quantitatively determined by Albanese et al. (A3) who found in the amount of the nondiffusible fraction corresponding to one liter of urine as much as 32.8 mg tryptophan, 18.0 mg phenylalanine, 16.2 mg methionine, 15.2 mg cystine, 13.1 mg arginine, 6.7 mg histidine, and 3.9 mg tyrosine. 

Amino acids and some small peptides are absorbed into the enterocytes in the jejnnnm. The transport of amino acids from the lumen into the ceU is an active process, coupled to the transport of Na ions down a concentration gradient. There are at least six carrier systems with different amino acid specificities neutral amino acids (i.e. those with no net charge, e.g. branched-chain amino acids) neutral plus basic amino acids imino acids (proline, hydroxyproline) and glycine basic amino acids (e.g. arginine and lysine) P-amino acids and taurine acidic amino acids (glutamic and aspartic acids). 

Data of Table III agree in some detail with the physical conclusion that elastin is not a collagen. The former is relatively low in residues with polar side chains hydroxyproline, glutamic and aspartic acids, arginine, lysine, serine, and threonine. It is particularly rich in glycine, alanine, the leucines and valine, residues whose side chains are nonpolar. Elastin and collagen are similar only in their moderately high proline contents and in their low proportions of histidine, cystine, tyrosine, and tryptophan. 

No activity was detected with the a-keto acid analogs of glycine, glutamine, asparagine, phenylalanine, tyrosine, tryptophan, arginine, citrulline, and aspartate. 

Polymer additives can improve manufacturing processes and product quality, as they aid the formation of a continuous coating phase without any detrimental effect to the polymer. Biomedical applications of acrylic terpolymer with arginylglycylaspartic acid, i.e., a tripeptide composed of L-arginine, glycine and L-aspartic acid peptides, have been studied by Fussell and Cooper [39]. Chauhan and co-workers have investigated the biological activities of synthesised terpolymers based on p-hydroxybenzaldehyde... 

The major components are glutamic acid and its amide, alanine, and aspartic acid. Other amino acids include glycine, phenylalanine, tryptophan, leucine, isoleucine, lysine and cystine. Trace amounts of valine, arginine, proline, serine and threonine are also present. The results of two recent studies on the quantification of amino acids in the serum generated from the acid coagulation of latex are shown in Table 3.8 and confirm that the top three amino acids in the serum of latex by weight are aspartic acid, glutamic acid and alanine. 

Mutations that occurred in the carboxyl (C) terminal domain (DOM) of pepsin serine at position 196 of pepsin mutated to arginine, aspartic acid at position 200 mutated to glycine, and glutamic acid at position 202 mutated to lysine.
