The genetic evidence for the role of AMPK in the hypothalamus is less clear because the loss of the AMPKa2 subunit in specific hypothalamic cell types resulted in the opposite pheno- type ... synthesis is the carboxylation of acetyl-CoA to form malonyl-CoA, catalyzed by ACC – the key reg- ulatory enzyme in the pathway. Malonyl-CoA serves as the b...

Under the in vitro assay conditions of the ... 13cROL in the absence of LRAT. Thus, we separately calcu- lated the K m of RPE65c, determining that they were 1.91 l M for 11cROL production and 2.95 lM for 13cROL production....
