The Correlation between Structure and Tritium Incorporation During Labeling by the Wilzbach MethodMany attempts have been made to find a pattern for tritium incorporation during Wilzbach labeling of organic molecules [.]. Unfortunately, it is still imposible to make more than a rough prediction about tritium incorporation.

Synthesis of 32P-, 14C-, and 3H-Labeled Lecithins and Their Use in Studies on Lipid MetabolismStudies on the pathway of degradation of phospholipids in animal tissues prompted the use of labeled or doubly labeled lecithins. Since such compounds are not yet available, the investigator has to prepare them from labeled materials by either biochemical or chemical procedures.

Growing Older and Staying in Shape,otides. Compared to the methods already in use, these new methods have the advantages of somewhat greater yields of label incorporated into the pyridine nucleotides and the potential of producing pyridine nucleotides with greater specific activities. As such, they should serve as useful additions to

To extend these findings, we turned to the use of tritium-labeled substrates. Glucose-1-H., glucose-6-H., and H..O were used in mammary gland and adiposetissue [.]. Results with these su

Ruzicka, Reichstein, and Fürst [.] and others [.] first demonstrated the possibility of its synthesis from steroids other than cardenolides by means of the Reformatsky reaction [.]. By reaction of various 21-acyloxypregnanone-(20) derivatives with bromacetic acid ethyl ester and zinc, they obtai
