Verified step by step guidance

Understand the concept of protein breakdown: Proteins are macromolecules made up of amino acids linked by peptide bonds. When proteins are broken down, these peptide bonds are hydrolyzed, releasing free amino acids as the building blocks.

Review the types of nutritional formulas: Each formula type represents a different level of complexity in nutrient composition. For example, polymeric formulas contain intact macromolecules, while elemental formulas contain nutrients in their simplest forms.

Focus on the elemental formula: Elemental formulas are designed for individuals with compromised digestion or absorption. They contain nutrients in their most basic forms, such as free amino acids instead of intact proteins or peptides.

Compare the other formula types: Oligomeric formulas contain partially digested proteins (peptides), polymeric formulas contain intact proteins, and modular formulas are customizable formulas that may include specific macronutrients but not necessarily free amino acids.

Conclude that the elemental formula is the correct answer because it contains proteins that have been fully broken down into free amino acids, making it suitable for individuals requiring easily digestible nutrients.
