Spectral properties of chloroplast membranes as a function of physiological temperatures


, : Spectral properties of chloroplast membranes as a function of physiological temperatures. Biochemical & Biophysical Research Communications 89(2): 542-546

The absorption spectrum of [barley] chloroplasts changes as a function of temperature. As chloroplasts are cooled from room temperature to 10.degree. C, there are increases in absorption at 675, 500 and 436 nm, plus a small decrease at 685 nm. As the chloroplasts are heated to 34.degree. C, there are decreases in absorption at 675, 500 and 436 nm plus increases in absorption at 690 and 400 nm. Apparently the temperature dependent change in phase of the membrane lipids (solid to liquid crystal state) modifies the state of chlorophyll aggregation.

DNA replication plays a central role in living organisms. Unregulated or uncontrollable DNA replication is well known to result in many pathological states, such as cancer, autoimmune diseases, and viral/bacterial infections. We report that an apt...

This paper reports evidence for a hormonal regulation of a new rat serum protein (female specific protein, FP) which is only demonstrable in female rats. Male and female rats were treated with testosterone and estrogen. The FP was assayed with imm...
