The binding specificity of amino acid transport system y+L in human erythrocytes is altered by monovalent cations
(1996)
System y+L is a broad-scope amino acid transporter which binds and translocates cationic and neutral amino acids. Na+ replacement with K+ does not affect lysine transport, but markedly decreases the affinity of the transporter ...
Rapid and simple HPLC method for the simultaneous determination of urocanic acid isomers in human skin
(2012)
A high-performance liquid chromatography (HPLC) method for the determination of urocanic acid isomers extracted from human skin has been developed. Urocanic acid is a compound present in skin, accumulated in trans form ...
Kaurenolides and fujenoic acids are side products of the gibberellin P450-1 monooxygenase in Gibberella fujikuroi
(2004)
The steps involved in kaurenolide and fujenoic acids biosynthesis, from ent-kauradienoic acid and ent-6α,7α-dihydroxykaurenoic acid, respectively, are demonstrated in the gibberellin (GA)-deficient Gibberella fujikuroi ...
Comparison of fatty acid profiles of dried and raw by products from cultured and wild fishes
(Wiley, 2017)
Fish by-products may become alternative sources of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, due to the high enzymatic activity in these biological tissues, special care must be taken to prevent ...
Restudy of the reaction of gallic acid and chloroacetic acid
(SOCIEDAD CHILENA DE QUIMICA, 1997-12)
We report the reaction of gallic acid with chloroacetic acid and three equivalents of sodium hydroxide. In this reaction, 2,6-dihydroxy-4-carboxyphenoxyacetic acid (A) is produced instead of 2,3-dihydroxy-5-carboxyphenoxyacetic ...
Evaluation of the stability of fatty acids in erythrocytes from human umbilical cord
(Wiley, 2020)
The interest in the amount of polyunsaturated fatty acids (PUFA) in the umbilical cord blood (UCB) is increasing, but the stability of erythrocyte PUFA in these samples during storage and washing of the erythrocytes has ...
Vegetable oils rich in alpha linolenic acid allow a higher accretion of n-3 LCPUFA in the plasma, liver and adipose tissue of the rat
(Instituto de la Grasa, 2014)
ALA is the precursor of EPA and DHA and its dietary availability is limited. Vegetable oils rich in
ALA (48–64%) are alternatives for increasing its consumption. The conversion of ALA into EPA and DHA and
the ratio ...
A search in rat brain cortex synaptic vesicles for endogenous ligands for kainic acid receptors
(1982)
Conditions were found for stabilizing rat brain cortex kainic acid (KA) receptors. Such receptors had the same Hill number (about 0.6) for KA and for glutamate. The receptors were then used as detectors for endogenous ...
Hydroxamic acids accumulation by wheat callus
(1990)
Hydroxamic acids were quantified by HPLC in leaves of one-week-old seedlings and in 30 day-old callus tissues of four wheat cultivars. Leaves accumulated preferentially 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA). ...
Hydroxamic acids (4-hydroxy-1,4-benzoxazin-3-ones), defence chemicals in the gramineae
(1988)
Hydroxamic acids of the type 4-hydroxy-1,4-benzoxazm-3-ones constitute one of the most extensively studied secondary metabolites m relation to host plant resistance to pests and diseases They play a maJor role in the defence ...
