Albumin dialysis did not significantly affect the amino acid profile in the controls. Albumin dialysis results in a significant decrease in circulating phenolic aromatic amino acids and improvement of hepatic encephalopathy in patients with severe liver failure.
Experiments with model solutions suggest that serum albumin has a high capacity for binding aromatic amino acids (stabilized by hydrophobic interactions) at neutral pH and this is responsible for the NMR‐invisibility of Tyr and Phe in blood plasma.
In other respects the albumin fractions from all three species were similar and represent balanced sources of all the essential amino acids except possibly tryptophane (not determined).
This suggests that albumin may have a role in the metabolism of endogenous and exogenous aromatic amides, including drugs and xenobiotics.
We conclude that infused amino acids promote the synthesis of albumin equally effectively in the presence or absence of a small amount of added glucose.
A remarkable role of aromatic amino acids was uncovered.
However, according to recent animal studies, the redox state of serum albumin is modulated by albumin turnover and may also reflect amino acid/protein nutritional status.
It is concluded that amino acids play an important role in the control of albumin synthesis and that more than one mechanism is probably involved.

The rate of synthesis of albumin and, thus, the rate of its secretion is linked most closely to the supply of amino acids.
The results group well to the amino acid type, i. e., hydrophobic, polar, and aromatic ones.

Isolated soly protein plasma속 amino acid content3 answersThe amino acid content of isolated soy protein from plasma was found to be significantly higher in experimental soybean lines developed in a study by Alaswad et al.. These lines were created by crossing a transgenic soybean line with elevated levels of sulfur amino acids with a high protein Korean soybean cultivar. The experimental lines showed an increase in protein content ranging from 41.3% to 47.7%. Additionally, the sulfur amino acid (cysteine + methionine) content in the experimental lines ranged from 1.1% to 1.26%, compared to 0.79% in the parent cultivar. The study also revealed an overall increase in the different subunits of 7S β-conglycinin and 11S glycinin, which are responsible for the observed increase in total protein content.

Is the Phenylalanine a biomarker?5 answersPhenylalanine has been identified as a potential biomarker in several studies. Oliva et al. found that phenylalanine displayed a high correlation with other amino acids in human dermal fibroblasts, suggesting it may be a suitable biomarker for estimating cellular content in cultured fibroblasts. Steventon and Mitchell investigated the S-oxidation of S-carboxymethyl-l-cysteine and found that phenylalanine hydroxylase, the enzyme responsible for this biotransformation reaction, may be a biomarker of disease susceptibility in Parkinson's disease and Amyotrophic lateral sclerosis. Additionally, McPherson and Türemen proposed that protein-bound 3,4-dihydroxyl-l-phenylalanine (l-DOPA), formed on 3'-hydroxylation of tyrosine residues, could serve as a biomarker for diseases associated with oxidative stress. These findings suggest that phenylalanine has the potential to be a biomarker in various diseases and cellular contexts.
What makes albumin a potential drug delivery coating material?0 answersAlbumin is a potential drug delivery coating material due to its versatility and ability to enhance the pharmacological action of therapeutic payloads. It can bind to various kinds of peptidyl and non-peptidyl drugs through its hydrophobic binding pockets, conjugatable thiol residue, and surface-exposed N- and C-termini. Additionally, albumin can passively accumulate in inflamed tissues and solid tumors, making it suitable for targeted drug delivery. Albumin can also be combined with polymers to create nanoparticles that can carry a wide variety of drugs, including hydrophobic drugs, metal-based drugs, therapeutic proteins, and siRNA. Furthermore, albumin nanoparticles have improved pharmacokinetic properties, such as longer circulation time and disease-specific accumulation, making them promising for in vivo imaging and therapy. Overall, albumin's ability to bind to drugs, its targeted delivery potential, and its compatibility with polymers make it a promising material for drug delivery coatings.
