We have studied in the rabbit reticulocyte and the pigeon erythrocyte the interactions between Na+ and various neutral amino acids with respect to transport by an apparently ubiquitous Na+-dependent system that prefers the linear aliphatic and hydroxy aliphatic amino acids. In the series, alanine to norleucine, stronger and stronger apolar bonding to the transport site with increasing chain len...

We have prepared polyethylene glycol (PEG)-type, polymer-based monolithic columns (PEG-type columns) to study the basic properties of PEG-type monolithic polymers. Chromatographic characteristics of the PEG-type columns were obtained using a semi-micro HPLC system while polycyclic aromatic hydrocarbons and benzene derivatives having various functional groups were utilized as solutes. Results we...

The carboxyl functional group is represented as –COOH and is the end product of alcohol oxidation. The term carboxylic acid is little special in the sense that it represents two functional groups; first a carbonyl group and second hydroxyl group. One can say that in the carboxyl group a hydroxyl group is bonded to a carbonyl (>C = O) group. It is often represented as CO2H or COOH. Carboxylic ac...

The serotonin1A (5-HT1A) receptor is an important neurotransmitter receptor that belongs to the G protein-coupled receptor (GPCR) family. It is implicated in a variety of cognitive and behavioral functions and serves as an important drug target for neuropsychiatric disorders such as anxiety and depression. Previous work from our laboratory has demonstrated that membrane cholesterol plays an imp...
