Explain what happens to excess amino acid in the liver of humans.
Answer Text: - The amino acids are broken down into amino group (#NH_2#) and carboxyl group (COOH), i.e deamination. The aminogroup combines with hydrogen forming highly toxic ammonia.- It immediately undergoes ornithine cycle where it combines with carbon (IV) oxide forming urea that is less toxic that is removed by the kidneys.- The carboxyl group is converted to glucose/ carbohydrates and then oxidized to yield energy or is converted into neutral fats and deposited in adipose tissue
