Xenogeneic, extracorporeal liver perfusion in primates improves the ratio of branched-chain amino acids to aromatic amino acids (Fischer's ratio) [PDF]

open access: yes, 1999
In fulminant hepatic failure (FHF), the development of hepatic encephalopathy is associated with grossly abnormal concentrations of plasma amino acids (PAA).

Effect of animal and industrial trans fatty acids on HDL and LDL cholesterol levels in humans - a quantitative review [PDF]

open access: yes, 2010
Background: Trans fatty acids are produced either by industrial hydrogenation or by biohydrogenation in the rumens of cows and sheep. Industrial trans fatty acids lower HDL cholesterol, raise LDL cholesterol, and increase the risk of coronary heart ...

Preparation of alkanesulfonic acids by photooxidation of dialkyl disulfides.

open access: yes, 1994
A soln. of a dialkyl disulfide in an alc. is irradiated with light having wavelength 200-320 nm in the presence of O to give alkanesulfonic acids. Irradn. of a soln.

Determination of organic acids evolution during apple cider fermentation using an improved HPLC analysis method [PDF]

open access: yes, 2008
An efficient method for analyzing ten organic acids in food, namely citric, pyruvic, malic, lactic, succinic, formic, acetic, adipic, propionic and butyric acids, using HPLC was developed. Boric acid was added into the mobile phase to separate lactic and

Experimental isovalthinuria. III. Induction by bile acids, and hypocholesterolemic agents [PDF]

open access: yes, 1963
Some bile acids (dehydrocholic, cholic, chenodeoxycholic, ursodeoxycholic, and deoxycholic acids), and some hypocholesterolemic agents (22, 25 diazacholestanol, 20,25-diazacholesterol, triparanol, and SKF 525-A) are the inducers of isovalthinuria in ...

Effects of dietary long-chain polyunsaturated fatty acids on plasma amino acids and indices of protein metabolism in infants: Results from a randomized clinical trial [PDF]

open access: yes, 1998
Background/Aim: Previous studies in vitro and in animals in vivo found that alpha-linolenic acid (C18:3 omega 3) may enhance oxidative damage of essential amino acids.

Analytical Chemistry of Impurities in Amino Acids Used as Nutrients: Recommendations for Regulatory Risk Management

open access: yes, 2022
Proteinogenic amino acids are natural nutrients ingested daily from standard foods. Commercially manufactured amino acids are added to a wide range of nutritional products, including dietary supplements and regular foods.

In Vitro Versus in Situ Ruminal Biohydrogenation of Unsaturated Fatty Acids from a Raw or Extruded Mixture of Ground Canola Seed/Canola Meal [PDF]

open access: yes, 2003
Raw or extruded blends of ground canola seeds and canola meal were used to compare in vitro and in situ lag times and rates of disappearance due to ruminal biohydrogenation of unsaturated fatty acids.

Dietary N-3 polyunsaturated fatty acids decrease biliary cholesterol saturation in gallstone disease [PDF]

open access: yes, 1992
Because fatty acid composition of biliary phospholipids influences cholesterol secretion into bile, we investigated whether replacement of n-1 monounsaturated or n-6 polyunsaturated fatty acids with n-3 polyunsaturated fatty acids in biliary ...

Preparation of alkanesulfonic acids by photo-oxidation of sulfur derivatives.

open access: yes, 1996
Alkanesulfonic acids RSO3H are prepd. by photooxidn. of RSR1 [R1 = H, R, SR; R = alkyl] in aq. or alc. MeCN at 200-400 nm. Thus, MeSO3H was obtained in 62% yield together with 19% H2SO4 by oxidizing MeSSMe in aq.
