Acyl-CoA is a group of CoA-based coenzymes that metabolize carboxylic acids. Fatty acyl-CoA 's are susceptible to beta oxidation , forming, ultimately, acetyl-CoA . The acetyl-CoA enters the citric acid cycle , eventually forming several equivalents of ATP .

Jan 24, 2020 · The main difference between acetyl CoA and acyl CoA is that acetyl CoA is the major end-product of the oxidative decarboxylation of pyruvate in the carbohydrate metabolism, later entering into the citric acid cycle whereas, at low glucose levels, acyl CoA is produced by the fatty acid activation, later entering into the β-oxidation of fatty acids.

Generated acyl-CoA as a raw material initiates the subsequent metabolism pathway to produce energy or synthesize diverse complex lipids. In addition, acyl-CoA can be deactivated to free FAs and CoA, and this process is mediated by acyl-CoA thioesterases (ACOTs).

Acyl-CoA analysis plays a critical role in understanding the effects of nutrition and dietary interventions on cellular metabolism. Researchers can assess changes in acyl-CoA profiles in response to different dietary components, such as fats, carbohydrates, or specific nutrients.

Their acyl-CoA products regulate metabolic enzymes and signaling pathways, become oxidized to provide cellular energy, and are incorporated into acylated proteins and complex lipids such as triacylglycerol, phospholipids, and cholesterol esters.

Acyl-CoA functions as an alternate acyl donor in E. coli and presumably other γ-proteobacteria (Fig. 1). There is no mechanism for forming acyl-CoA from acyl-ACP in E. coli, thus acyl-CoAs are exclusively formed from exogenous fatty acids.

This review evaluates the evidence for acyl-CoA partitioning by reviewing experimental data on proteins that are believed to contribute to acyl-CoA channeling, the metabolic consequences of loss of these proteins, and the potential role of maladaptive acyl-CoA partitioning in the pathogenesis of metabolic disease and carcinogenesis.

Sep 24, 2024 · The major acyl donor, acyl-CoA, enables modifications that impart distinct biological functions to both histone and non-histone proteins. These modifications are crucial for regulating gene expression, organizing chromatin, managing metabolism, and modulating the immune response.

Acyl-CoA formation initiates cellular fatty acid metabolism. Acyl-CoAs are generated by the ligation of a fatty acid to Coenzyme A mediated by a large family of acyl-CoA synthetases (ACS). Conversely, acyl-CoAs can be hydrolyzed by a family of acyl-CoA thioesterases (ACOT).

Their acyl-CoA products regulate metabolic enzymes and signaling pathways, become oxidized to provide cellular energy, and are incorporated into acylated proteins and complex lipids such as triacylglycerol, phospholipids, and cholesterol esters.

Acyl-CoA represents a broad category of CoA derivatives that include fatty acids with varying chain lengths, while Acetyl-CoA is a specific type of Acyl-CoA with an acetyl group (C₂H₃O) bound to coenzyme A.

Acyl-CoA Thioesterases Deactivate Fatty Acids within Cells. Esters of CoA constitute initial, as well as intermediate substrates in diverse cellular metabolic pathways.

Aug 1, 2020 · Compartmentalisation of acyl-CoA metabolism is key to connecting histone acylation in the nucleus to metabolic pathways. The metabolic role of many acyl-CoA species has been described only in mitochondria.

Acetyl-CoA, a prototypical acyl-CoA, is the product of several catabolic processes in the mitochondria, whereas in the cytosol, it is the primary substrate for anabolic processes, including de novo fatty acid and cholesterol synthesis. Acetyl-CoA is …

In this review, we cover the evidence for the involvement of acyl-CoAs in what has been termed lipotoxicity, the regulation of the acyl-CoA synthetases, and the emerging functional roles of acyl-CoAs in the major tissues that contribute to insulin resistance and …

Jul 1, 2022 · Acetyl CoA and acyl CoA are two types of coenzymes. Both have similar structures, are involved in fatty acid metabolism, and play key roles in energy production through catabolism. Despite these few similarities there are several differences between Acetyl CoA and Acyl CoA.

Jul 21, 2022 · Acyl-Co-As can modify protein through non-enzymatic acylation. By using a novel mass spectrometry probe, James et al. demonstrate that longer-chain (C13–C22) acyl-Co-As often constitute ∼60% of the acyl-CoA pool in tissues.

Feb 27, 2025 · The in vitro analysis of TANGO2-acyl-CoA binding was accomplished in black 96-well optical-bottom plates (Cat# 165305; Thermo Fisher Scientific). In this assay were used the purified TANGO2.Flag or TANGO2.∆NRDE.Flag and the fluorescently labeled lipids 16-NBD-16:0-CoA or 18-NBD-CoA 18:1. For direct binding, we used 2 µM of each NBD-acyl-CoA ...

Their acyl-CoA products regulate metabolic enzymes and signaling pathways, become oxidized to provide cellular energy, and are incorporated into acylated proteins and complex lipids such as triacylglycerol, phospholipids, and cholesterol esters.
