Acetyl-CoA is a metabolic intermediate that is involved in many metabolic pathways in an organism. It is produced during the breakdown of glucose, fatty acids, and amino acids, and is used in the synthesis of many other biomolecules, including cholesterol, fatty acids, and …

Jul 9, 2020 · Acetyl-CoA or acetyl coenzyme A is a component of cellular respiration (energy conversion) that adds acetyl groups to biochemical reactions. These reactions are used in the metabolizing of proteins, carbohydrates, and lipids that will provide energy sources in the forms of adenosine triphosphate (ATP), lactic acid, and ketone bodies.

Acetyl-CoA represents a key node in metabolism due to its intersection with many metabolic pathways and transformations. Emerging evidence reveals that cells monitor the levels of acetyl-CoA as a key indicator of their metabolic state, through distinctive protein acetylation modifications dependent on this metabolite.

Acetyl-coenzyme A (acetyl-CoA) is a key substrate for anabolic reactions and the sole donor of acetyl groups for protein acetylation. In this review, Kroemer and colleagues discuss how acetyl-CoA dictates the balance between cellular catabolism and anabolism by simultaneously operating as a metabolic intermediate and a second messenger.

4 days ago · Acetyl-CoA is a substrate for histone acetylation, a process that regulates gene expression by modifying chromatin structure. Histone acetyltransferases (HATs) transfer acetyl groups from acetyl-CoA to lysine residues on histones, weakening their interaction with DNA and making genes more accessible for transcription.

6 days ago · Acetyl CoA is a pivotal molecule in cellular metabolism, serving as a key link between various biochemical pathways. Its central role in energy production and biosynthesis impacts numerous physiological processes. Understanding acetyl CoA’s functions offers insights into metabolic health and potential therapeutic targets.

Acetyl-CoA is an acyl-CoA having acetyl as its S-acetyl component. It has a role as an effector, a coenzyme, an acyl donor and a fundamental metabolite. It is functionally related to an acetic acid and a coenzyme A. It is a conjugate acid of an acetyl-CoA (4-).

Jan 16, 2025 · Acetyl-CoA plays a foundational role in the citric acid cycle, a central metabolic pathway integral to cellular respiration. This cycle, also known as the Krebs cycle, occurs in the mitochondria and is responsible for oxidizing acetyl groups to produce energy-rich molecules.

2 days ago · Acetyl-CoA synthetase (Acs) generates acetyl-coenzyme A (Ac-CoA) but its excessive activity can deplete ATP and lead to a growth arrest. To prevent this, Acs is regulated through Ac-CoA-dependent ...

Acyl-CoA, a vital molecule in the biochemical world, plays a significant role in various metabolic pathways. But what exactly is Acyl-CoA? Let’s break it down. The term "Acyl-CoA" refers to a group of coenzymes involved in the metabolism of fatty acids and other acyl compounds.
