Effect of hypoxia in vitro on phospholipid composition of isolated mitochondria and lysosomes of rabbit heart.

: Phospholipid composition of mitochondrial and lysosomal fractions of the rabbit heart under hypoxic conditions was studied. Only when the two fractions were incubated together under hypoxic conditions for 10 or 60 minutes, did phosphatidylethanolamine and phosphatidylcholine concentrations of mitochondria and lysosomes decrease significantly, suggesting that there is certain interaction between these organelles under induced hypoxia in vitro.
