What does AA mean in MEDICAL

Amino acids are small molecules that are composed of both an amine group (NH2) and a carboxylic acid group (COOH). They play a crucial role in many biological processes by participating in protein synthesis, cellular metabolism and other metabolic pathways.

There are 20 different types of amino acids classified into three categories based on their structure. These include essential amino acids, non-essential amino acids, and conditional amino acids. Essential amino acids cannot be synthesized by our bodies so they must come from diet sources such as meats, eggs, dairy products, legumes or plants. Non-essential amino acids can be synthesized by our bodies from other substances in the diet. Conditional amino acids are not essential under normal circumstances but may become necessary during times of illness or stress.

The easiest way to ensure you're getting enough essential amino acids is through eating a varied diet full of lean proteins such as lean meats, poultry or fish; beans; eggs; nuts; and whole grains. Vegetarians/vegans may need to supplement with additional plant-based sources like peas, rice or soybeans to get all the essential amino acids they need each day. Additionally, there are supplements available that contain all nine essential AA's needed for optimal health.
