Kinetics Of

The kinetics of induced electron transfer reaction has been attempted presently with Tetra Methyl Ammonium Chloro Chromate (TMACC) and pentaammine cobalt (III) complexes of α-hydroxy acid in the presence of micelles. The Tetra Methyl Ammonium Chloro Chromate (TMACC) oxidizes cobalt (III) bound and unbound α-hydroxy acids. In Tetra Methyl Ammonium Chloro Chromate (TMACC) induced electron transfer in the complex, the intermediate radical formed dissociates in a nearly synchronous C-C bond cleavage and the rest of it proceeding with C-H fission yielding cobalt (III) complex. With increase in surfactant Sodium Lauryl Ethersulphate (SLES) concentration, an increase in the rate was observed.

Psychosocial Benefits

Alpha hydroxy acids are used extensively by patients and consumers for restorative cutaneous purposes. The current study of 32 patients evaluated the clinical and psychosocial effects of this cosmetic therapy. After 12 weeks, significant clinical improvements were found for facial skin tone and fine wrinkling, as well as for patient-reported satisfaction with physical appearance and with marital or relationship quality.

Reducing Equivalents

Observations on systems reconstituted in vitro with different starting substrates (2-hydroxy-acids, 2-oxo-acids or leucine) indicate that a branched-chain 2-hydroxy-acid/2-oxo-acid shuttle for the transfer of reducing equivalents from cytosol to mitochondria may be operational in mouse sperm. Evidence is presented suggesting that the 2-oxo-acids produced by intramitochondrial oxidation of 2-hydroxy-acids ingressed from the cytosol can recycle back into the external phase. Observations in vitro demonstrate that, in addition to the branched-chain 2-hydroxy-acid/2-oxo-acid shuttle, the malate/aspartate system is also active in mouse sperm. On the contrary, the lactate/pyruvate redox couple does not appear to function as part of a shuttle system in mouse sperm mitochondria. The glycerol 3-phosphate shuttle probably is not functionally significant in mouse spermatozoa, since the activity of the ‘soluble’ glycerol 3-phosphate dehydrogenase is very low.
