Catecholamine Biosynthesis Pathway

The video tutorial explains catecholamine synthesis, detailing the conversion of phenylalanine to tyrosine, and further to dopamine, norepinephrine, and epinephrine. It covers the enzymes involved, such as phenylalanine hydroxylase and tyrosine hydroxylase, and the role of cofactors like tetrahydrobiopterin and vitamin B6. The tutorial also discusses genetic disorders affecting this pathway, including phenylketonuria and albinism.
