This is the first comprehensive study of the genetic analysis of the majority of oleoresin components of slash pine (Pinus elliottii). Pine oleoresin, the resin secreted from the pine tree, is a raw material widely used in industrial products. The objective of this study was to explore the genetic variation and correlation between the major oleoresin components of 50 open pollinated families of...

The exact structure of the type-I11 isomer penta-, hexaand hepta-carboxylic porphyrinogens that are involved as intermediates in the conversion of uroporphyrinogen I11 into coproporphyrinogen 111 have been elucidated (Jackson et al., 1976). The corresponding porphyrins are to be found in the urine of patients suffering from the porphyrin-overproduction diseases symptomatic porphyria and congeni...

13-Aminotridecanoic acid, the monomer for nylon 13, was synthesized from commercial erucic acid or its derivatives by several methods in a study to determine the method of choice, which involved oxidative ozonolysis of eruconitrile, followed by esterification before isolation to give methyl 12-cyanododecanoate. The cyano ester was then catalytically reduced and hydrolyzed, without isolation of ...

1. After administration of 600mg of 3H-labelled aldosterone to human volunteers, 57 mg of homogeneous acid-labile conjugate was isolated from the urine and identified as aldosterone 18 beta-D-glucosiduronic acid. 2. Esterification and acetylation of the conjugate gave a tetra-acetate methyl ester, which, by measurement of the optical rotation and nuclear-magnetic-resonance spectrum, was shown t...
