Answer:
Examples of serious health problems that can result if amino acids do not function properly include:
a) Celiac disease
d) PKU
Celiac disease involves an autoimmune response to gluten, a protein found in wheat, barley, and rye. It can lead to damage to the small intestine and nutrient malabsorption, which can affect amino acid metabolism.
PKU (phenylketonuria) is a genetic disorder characterized by the body's inability to metabolize the amino acid phenylalanine properly. If left untreated, PKU can lead to intellectual disability, developmental delays, and other serious health problems.
