Amino acids are the chemical units or “building blocks,” that make up proteins. They also are the end products of protein digestion, or hydrolysis. Amino acids contain about 16 percent nitrogen. Chemically, this is what distinguishes them from the other two basic nutrients, sugars and fatty acids, which do not contain nitrogen.

WebThis movement of individual amino acids requires special transport proteins and the cellular energy molecule, adenosine triphosphate (ATP). Once the amino acids are in the blood, they are transported to the liver. As with other macronutrients, the liver is the checkpoint for amino acid distribution and any further breakdown of amino acids ... WebThese transporters include the following: 1) System L, which mediates high affinity, sodium-independent uptake of zwitterionic amino acids with “large, neutral” side chains, including L-leucine, L-phenylalanine, L-tryptophan, L-tyrosine, L-isoleucine, L-methionine and L-valine; 2) System y +, which mediates moderate affinity, sodium-independent … WebA close up of the villi in the small intestine Cross-section of a villus These all increase the surface area over which digested food – now simple molecules – is absorbed.
