Two garlic subspecies (n = 11), Allium sativum L. var. opioscorodon (hardneck) and Allium sativum L. var. sativum (softneck), were evaluated for their free amino acid composition. The free amino acid content of garlic samples analyzed ranged from 1121.7 to 3106.1 mg/100 g of fresh weight (mean = 2130.7 +/- 681.5 mg/100 g). Hardneck garlic had greater methiin, alliin, and total free amino acids ...

Concentrations of soluble soil sugars, soluble phenolic acids, and free amino acids were measured in three forest communities at the FACTS-II Aspen FACE Site near Rhinelander, WI, in order to better understand how elevated atmospheric CO2 and O3 are influencing soil nutrient availability and cycling. Sugars, phenolic acids, and amino acids are mostly derived from plant and microbial processes, ...

Plant bioactive metabolites play a pivotal role in protection against environmental stresses and offer great potential for nutraceutical exploitation. In this sense, halophytes present an exceptional opportunity sustainable saline agriculture since they can massively accumulate under stressful conditions. We investigated the responses of halophyte Crithmum maritimum to increasing salinity, nutr...

OBJECTIVE To study the effects of a total parenteral nutrition solution changing branch-chain amino acid concentrations and/or nitrogen supply on protein metabolism, length of stay, and mortality rate; and to evaluate the unique metabolic status of sepsis that leads to a search for specific total parenteral nutrition formulas. DESIGN Prospective, randomized, and multicenter study. SETTING I...

HE INVESTIGATION of the excretion of free amino acids after burnB and surgery in humans (1-6) has given rise to conflicting results. The discrepancies reported quite probably have three principal causes: (1) inadequately controlled observations; (2) comparison of observations from widely disparate environments; and (3) the use of relatively semiquantitative technic for determining amino acids, ...

changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. furthermore, acid-base condition is achieved in part by the alteration of dietary amino acids pattern and quantity. therefore, a trial was conducted in a completely randomized design to evaluate performance, carcass characteristics, plasma electrolyte and uric acid concentrations of 19 and 28-da...

1. Measurements were made of the rate of incorporation of (14)C from uniformly (14)C-labelled glucose into individual amino acids of rat brain and liver. 2. At 2.5 min. after intravenous injection of uniformly (14)C-labelled glucose, about 30% of the total radioactivity in the brain was present in the five amino acids studied. At 30 min. after subcutaneous injection the distribution of (14)C in...

The paper presents the results of the influence of anionic-type detergent containing sodium tripolyphosphate and ethoxylated oleylcetyl alcohol on the type and quantity of present amino acids in the fermentation broths of the fungi Aspergillus niger, Alternaria tenuis and Fusarium oxysporum cultivated on a medium with the addition of 1% detergent as a function of their application in the proces...

BACKGROUND Numerous studies have evaluated protein and amino acid levels in human milk. However, research in this area has been limited by small sample sizes and study populations with little ethnic or racial diversity. OBJECTIVE Evaluate the protein and amino acid composition of mature (≥30 days) human milk samples collected from a large, multinational study using highly standardized methods...

Animals rely on their diet for amino acids that they are incapable either of synthesizing or of synthesizing in sufficient quantities to meet metabolic needs. These are the so-called 'essential amino acids'. This set of amino acids is similar among the vertebrates and many of the invertebrates. Previously, no information was available for amino acid synthesis by the most primitive invertebrates...
