Four other AAs, including arginine and cysteine, are ‘semi-essential’, meaning there are biosynthetic pathways to produce them in humans, but a dietary source is required in some circumstances.

L-arginine helps in production of nitric oxide. L-arginine-nitric oxide biosynthetic pathway in pregnancy helps with placental vascular development, fetal growth and improving birth outcomes.
