Surveillance of C-Allocation in Microalgal Cells

open access: yesMetabolites, 2014
When microalgae are exposed to changing environmental conditions, e.g., light-dark cycles or oscillations in nutrient availability (CO2, nitrogen, phosphate or silicate) they respond with metabolic changes in the carbon allocation pattern.

Conformational disorder in unsaturated phospholipids by FTIR spectroscopy

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 1996
Conformational disorder in liquid alkenes and in the L alpha and Hparallel phases of some unsaturated phospholipids has been monitored by FTIR spectroscopy. The CH2 wagging region (1330-1390 cm-1) in saturated chains contains vibrations of particular 2- and 3-bond conformational states as follows: 1341 cm-1, end-gauche (eg); 1352 cm-1, double gauche ...
