ANATOMY

Detailed explanation-1: -The liver also plays an important role in the metabolism of proteins: liver cells change amino acids in foods so that they can be used to produce energy, or make carbohydrates or fats. A toxic substance called ammonia is a by-product of this process.

Detailed explanation-2: -The liver plays a central role in amino acid (AA) metabolism in humans and other animals. In all mammals, this organ synthesizes many AAs (including glutamate, glutamine, alanine, aspartate, asparagine, glycine, serine, and homoarginine), glucose, and glutathione (a major antioxidant).

Detailed explanation-3: -The essential amino acids are not synthesized in humans but are synthesized in either plants or bacteria.

Detailed explanation-4: -The liver is one of the most important organs for making proteins. It produces or transforms millions of protein molecules each day. Proteins are made from amino acids.
