Sexual Induction in Volvox Carteri
The study of the dependence of reactions on the concentration of various compounds is often of great value in determining reaction mechanisms . In chemical kinetics, it is often found that, according to van't Hoff's rule, the order of dependence of a reaction on the concentration of some compound involved in that reaction is equal to the number of molecules of the compound involved in each reac...
متن کاملA Kinesin, InvA, Plays an Essential Role in Volvox Morphogenesis
In Volvox carteri adults, reproductive cells called gonidia are enclosed within a spherical monolayer of biflagellate somatic cells. Embryos must "invert" (turn inside out) to achieve this configuration, however, because at the end of cleavage the gonidia are on the outside and the flagellar ends of all somatic cells point inward. Generation of a bend region adequate to turn the embryo inside o...
متن کاملl-Glutamic acid hydrochloride at 153 K
THE TITLE COMPOUND [SYSTEMATIC NAME: (S)-1,3-dicarboxy-propanaminium chloride], C(5)H(10)NO(4) (+)·Cl(-), has been investigated previously by Dawson [Acta Cryst. (1953). 6, 81-83], with R = 0.106 and without the location of H atoms, and then by Sequeira, Rajagopal & Chidambaram [Acta Cryst. (1972). B28, 2514-2519] using neutron diffraction with R = 0.043. The present determination at 153 K has ...
متن کاملMetal ion-binding properties of L-glutamic acid and L-aspartic acid, a comparative investigation
A comparative research has been developed for acidity and stability constants of M(Glu), M(Asp) and M(Ttr) complexes, which have been determined by potentiometric pH titration. Depending on metal ion-binding properties, vital differences in building complex were observed. The present study indicates that in M(Ttr) complexes, metal ions are arranged to the carboxyl groups, but in M(Glu) and M(As...
