title: Effects of temperature oscillations on the distribution of 65Zn on cytoplasmic proteins.
abstract: 1. Oscillating temperatures cause an increase in 65Zn uptake into the digestive gland of M. edulis when compared with the effects of constant temperatures. 2. The increased uptake is associated with a change in the distribution of 65Zn onto cytoplasmic proteins. There is a fall in the percentage of metal on the greater than 70 K dalton fraction and a rise in the 3 K dalton fraction. 3. A possible hypothesis is produced to explain these effects in terms of heat lability of metal-protein ligands.
