Web4 sep. 2024 · A lactate receptor, the hydroxycarboxylic acid receptor 1 (HCA1), is present in the brain, but whether it is located in the CP or in other periventricular structures has not been studied. Here, we investigated the distribution of HCA1in the cerebral ventricular system using monomeric red fluorescent protein (mRFP)-HCA1reporter mice. WebBoric acid catalyzes the selective esterification of α-hydroxycarboxylic acids without causing significant esterification to occur with other carboxylic acids. The procedure is simple, high-yielding, and applicable to the esterification of α-hydroxy carboxylates in the presence of other carboxylic acids including β-hydroxyacids within the same molecule.
