Combined with lab automation, such amino acid sets render larger screening campaigns involving more amino acid positions feasible. For much larger numbers of targeted positions in Sav, ISM, potentially in combination with reduced amino acid alphabets, appears to be a promising strategy, as it offers a good tradeoff between experimental effort and the probability of finding highly active ...
amino acid screening locally so that only the possible/probable abnormalities are referred to aspecialistlaboratoryfor confirmation. Clinical chemistry laboratories that perform amino acid investigations must, therefore, be able not only to provide both rapid and accurate identifica tion of amino acid abnormalities, but also to interpret their findings and decide upon the most .

The Na+glucose symporters and Na+amino acid symporters do have a limit to the amount of glucose or amino acids that can be reabsorbed, just as an elevator has a limit to the amount of people that it can transport at one time; this limit is called the _____.

Urinary amino acid excretion was determined in 31 leukemic patients and 29 normal individuals by rapid gas chromatographic analysis of 16 amino acids as their Nacetylnpropyl esters. The leukemic patients were concurrently undergoing, or had recently completed, chemotherapy. It was found that aspartic acid, threonine, and serine were of significance in distinguishing between .
Herein, a crossreactive fluorescent sensor array based on amino acidfunctionalized carbon nanodots (CDs) was designed for simultaneous qualitative and quantitative analysis of seven kinds of OAs, including homovanillic acid (HVA), vanillylmandelic acid (VMA), 3hydroxyisovaleric acid (3HA), lactic acid (LA), pyruvic acid (PA), glutaric acid (GA), and methylmalonic acid .
The Amino Acids Analysis, Urine is a first morning void (FMV) collection that measures 40 amino acids and intermediary metabolites. The report includes personalized amino acid recommendations based on amino acid levels, and functional vitamin and mineral cofactor recommendations based amino acid metabolism. Amino acids are important building blocks .
Amino acids are present in urine in excessive amounts: (i) if the plasma concentration is excessive (eg, Phenylketonuria) (ii) if renal tubular reabsorption is impaired (eg, Fanconi syndrome). Edwards MA et al. Ann Clin Biochem 1988; 25: 129141.

Amino acids, Urinary Hyperargininemia. This defect is characterized by elevated blood and cerebrospinal fluid arginine levels, low erythrocyte levels of arginase (reaction 5, Figure 299), and a urinary amino acid pattern resembling that of pattern may reflect competition by arginine with lysine and cystine for reabsorption in the renal tubule.
Metabolomic analysis of urinary amino acids (AAs) from patients with bladder cancer was performed by gas chromatography–mass spectrometry. The β .

· These organic acids can be measured in the urine via routine screening tests. Other inborn errors of metabolism can also be detected by urinary organic acids, including: Alkaptonuria: homogentisic acid (8, 9) Canavan disease: Nacetylaspartic acid (10, 11) MalonylCoA decarboxylase deficiency: malonic acid (12, 13) Maple syrup urine disease (MSUD): 3 .

In addition to excess cystine in the urine, the disorder is associated with increased urinary excretion of the dibasic amino acids arginine, lysine, and ornithine. However, clinical consequences are only associated with the increased urinary cystine and is due to the poor solubility of this homodimeric compound. Cystine will precipitate in the urine resulting in the .
