Web2 sep. 2015 · Further iodination couples two residues of DIT, both still in peptide linkage, to produce T4, principally at residues 5 in the Tg polypeptide chain. When thyroid hormone is needed, Tg is internalized at the apical pole of thyrocytes, conveyed to endosomes and lysosomes and digested by proteases, particularly the endopeptidases cathepsins B, L, … WebTryptophan is an α-amino acid which is used in the biosynthesis of proteins and is encoded by the codon UGG. It is denoted as Trp or W. It consists of an α-carboxylic acid group, α-amino group, and a side chain indole, therefore making it a non-polar aromatic amino acid. It is required for humans but cannot be synthesized by the body.
