Antimutagenic and some other effects of conjugated linoleic acid.
Conjugated linoleic acid (CLA) is a collective term for positional and geometric isomers of octadecadienoic acid in which the double bonds are conjugated, i.e. contiguous. CLA was identified as a component of milk and dairy products over 20 years ago. It is formed as an intermediate in the course of the conversion of linoleic acid to oleic acid in the rumen. The predominant naturally occurring ...
متن کاملConversion of oleic acid to linoleic acid.
Reports from this laboratory have described the formation of palmitoleic and oleic acids from their saturated counterparts by enzyme systems of yeast (2, 3). For introducing a double bond into the 9,lO position of the aliphatic chain, the desaturating enzymes, acting on the coenzyme A derivatives of the fatty acids, require reduced triphosphopyridine nucleotide, and molecular oxygen as hydrogen...
متن کاملUV - Induced Mutagenesis in Lactic Acid Bacteria
Induced mutagenesis is widely used for selection of microorganisms producing biologically active substances and further improving of their activities. However, it is rarely used toward lactic acid bacteria (LAB) due to their genetic specificity. Determination of LABs sensitivity to UV light and evaluate the effectiveness of UV-induced mutagenesis by positive selection of antibiotic resistant mu...
متن کاملOleic acid versus linoleic and α-linolenic acid. different effects on Ca2+ signaling in rat thymocytes.
BACKGROUND Oleic acid is the principal fatty acid of olive oil composition and is reported to play a crucial role in its healthy aspects. However, the detailed mechanism of action is poorly understood. AIMS This study aims to elucidate the role of oleic acid in calcium signaling in rat thymocytes, in comparison to linoleic and linolenic acid. METHODS Fatty acids were applied to thymocytes i...
متن کاملLack of strand bias in UV-induced mutagenesis in Escherichia coli.
We have investigated whether UV-induced mutations are created with equal efficiency on the leading and lagging strands of DNA replication. We employed an assay system that permits measurement of mutagenesis in the lacZ gene in pairs of near-identical strains. Within each pair, the strains differ only in the orientation of the lacZ gene with respect to the origin of DNA replication. Depending on...
