acyl-carrier protein

The term "ACP" can refer to several things, including the African, Caribbean and Pacific Group of States or the American College of Physicians. In the context of biochemistry, ACP stands for acyl-carrier protein.1

Acyl-carrier protein (ACP) is a small molecule that plays a crucial role in the synthesis of fatty acids. It acts as a carrier for the growing fatty acid chain during the multi-step process of building these essential lipid components. The carbon atoms for fatty acids are derived from the breakdown of carbohydrates and other fatty acids, with acetyl coenzyme A being a key intermediate. ACP, often in conjunction with other enzymes, facilitates the addition of carbon units to form fatty acids like palmitic acid. This process requires energy, primarily from ATP, and involves several reduction and dehydration steps.23
