What are essential amino acids?

Essential amino acids are defined as amino acids that cannot be synthesized by the body and must therefore be obtained through dietary sources. This is fundamentally important for various physiological functions, including protein synthesis, tissue repair, and the production of hormones and enzymes. Since the body lacks the capability to produce these amino acids, it is crucial for individuals to consume them in adequate amounts from food, particularly from high-quality protein sources.

The knowledge about essential amino acids is vital for veterinary technicians as they need to understand the nutritional requirements of different species. For instance, cats are obligate carnivores and have specific essential amino acid requirements compared to omnivorous animals like dogs or humans. Understanding which amino acids are essential helps in formulating diets that meet the specific needs of the animals they care for, ensuring their overall health and wellness.
