Conversion of some C14-labelled compounds into the neutral lipid ofNeurospora crassa

Summary

Conidia-free mycelia ofNeurospora crassa converted C14-acetate into neutral lipid more efficiently than C14-labelled mevalonic acid or six other compounds tested. Pyruvate, glucose, and alanine contributed little to the neutral lipid fraction, but that contribution was mainly as fatty acids. Substantial losses of C14 as carbon dioxide indicated that all of the labelled compounds participated in cell metabolism.

Analysis of the fatty acids esterified to the neutral lipid of unlabelled mycelia showed that palmitic, oleic, and linoleic acids each comprised nearly one-third of the total while stearic, palmitoleic, and a small amount of unidentified acids contributed the remainder.
