Introduction: The catabolism of tyrosine is a vital biochemical pathway for B. Pharm students studying amino acid metabolism, enzymology, and metabolic disorders. This Student-friendly guide focuses on key enzymes (tyrosine aminotransferase, p‑hydroxyphenylpyruvate dioxygenase, homogentisate 1,2‑dioxygenase, maleylacetoacetate isomerase, fumarylacetoacetate hydrolase), cofactors (PLP, iron, glutathione), pathway intermediates (p‑hydroxyphenylpyruvate, homogentisic acid, fumarylacetoacetate) and clinical conditions such as alkaptonuria … Read more

The catabolism of phenylalanine is a vital biochemical pathway for B.Pharm students to master, linking amino acid metabolism, enzyme mechanisms, cofactor biochemistry and inborn errors like phenylketonuria (PKU). Phenylalanine is primarily converted to tyrosine by phenylalanine hydroxylase (PAH) with tetrahydrobiopterin (BH4) as cofactor; alternative transamination forms phenylpyruvate and downstream phenylacetate. Downstream tyrosine degradation yields fumarate … Read more
