Cysteine Biosynthesis

The video tutorial explains cysteine biosynthesis in humans, focusing on the conversion of serine to cysteine through a two-step enzymatic process involving pyridoxal phosphate-dependent enzymes. It highlights the role of Vitamin B6, an essential nutrient, in this process. The tutorial also previews upcoming topics on selenocysteine and taurine biosynthesis.

What are the implications of cysteine being a non-essential amino acid for humans?

Describe the two-step enzymatic process involved in converting serine to cysteine.
