Amino Acid Absorption

Definition

Amino acid absorption is the process by which amino acids are taken up by the intestines and enter the bloodstream after being broken down from proteins consumed in the diet.

Scientific / Technical Definition

Amino acid absorption refers to the physiological process involving the transport of amino acids across the intestinal epithelial cells. This process occurs after proteins are enzymatically digested into free amino acids, dipeptides, and tripeptides in the gastrointestinal tract. Absorption primarily takes place in the small intestine through specific transporters that facilitate the movement of amino acids into the enterocytes, and subsequently into the bloodstream.

Benefits

• Supports muscle repair and growth
• Contributes to neurotransmitter synthesis

Additional Information

• Importance: Amino acid absorption is crucial for protein synthesis, which is necessary for cell repair, growth, and overall metabolism. Efficient absorption ensures that the body has adequate building blocks for these vital functions.
