ethyl ester/potato

The unnatural long-chain OPCs, OPC-9:0 and OPC-10:0, were respectively synthesized from the ethyl esters of OPC-7:0 and OPC-8:0. C2-carbon elongation was achieved via alkylation of the enolate of tert-butyl acetate. The potato tuber-inducing activity of OPC-10:0, as well as OPC-8:0, -6:0 and -4:0,

BACKGROUND The origin of the raw spirits influences the sensory quality of rectified spirits that are subsequently used for the production of vodka. The aim of this research was to evaluate the effectiveness of two methods based on the comparison of profiles of volatile compounds [solid phase

The 2-oxoglutarate dehydrogenase complex constitutes a mitochondrially localized tricarboxylic acid cycle multienzyme system responsible for the conversion of 2-oxoglutarate to succinyl-coenzyme A concomitant with NAD(+) reduction. Although regulatory mechanisms of plant enzyme complexes have been

The inhibition constants for vanadate, chromate, molybdate, and tungstate have been determined with Escherichia coli alkaline phosphatase, potato acid phosphatase, and Helix pomatia aryl sulfatase. Vanadate was a potent inhibitor of all three enzymes. Inhibition of both phosphatases followed the

The inhibition of Helix pomatia arylsulfatase by the synergistic combination of N-acetyl-l-tyrosine ethyl ester and vanadate has been extended to affinity chromatography for purification. In the presence of vanadate, l-tyrosine ethyl ester (TEE), immobilized on CH-Sepharose 4B retained arylsulfatase

Eleven fungal endophytes were isolated from the plant parts of Z. nimmonii (J. Graham) Dalzell, an endemic species of the Western Ghats, India, a biodiversity hotspot area. The endophytic isolates were characterized by the sequencing of the Internal Transcribed Spacer (ITS) regions and

Water-soluble carbodiimide (1-ethyl-3-(3-dimethylaminopropyl)carbodiimide) (EDC) and glycine ethyl ester (GEE) as a nucleophile were used to modify the essential carboxyl group of phosphorylases. The inactive b form of the muscle phosphorylase was modified faster than the active a form and potato

Sweet potato (Ipomoea batatas) leaf (SPL) is an underused commercial vegetable with considerable bio-activities. By means of DPPH scavenging ability and α-glucosidase inhibitory oriented isolation, 9 and 7 compounds were isolated and identified, respectively. Among them,
