Absorption of Protein Amino acids absorbed mostly by active carrier-mediated transporters which are energy dependent. Amino acids are transported through a number of carriers. These are 2 types of carriers: Sodium dependent carriers Neutral amino acid carrier A phenylalanine and methionine carrier. A carrier specific to the amino acids (proline and hydroxyproline) Sodium independent carriers Neutral and lipophilic amino acids (leucine, isoleucine) Cationic amino acids (eg. lysine) Protein Biosynthesis Protein biosynthesis is called translation. It involves the transformation of information from the 4 letter language of nucleic acid into 20 letter language by structural protein. Requirements for translation: Involves mRNA + tRNA / Ribosomes Polypeptides are formed by sequential addition of amino acids in specific order by the information carried in the nucleotide sequence of mRNA.
