I want to know the answer to the following question:
What can be synthesized using carbohydrates and proteins?
All the background I'm provided with is that "During the 19th century, Jean-Baptiste Dumas and Justus von Liebig quarrelled over their shared belief that animals get their protein directly from plants (animal and plant protein are the same and that humans do not create organic compounds).". Is that enough to answer the question?
Answer: no
