To determine

To Identify: The source of the compounds needed to build proteins in the body.

Explanation of Solution

Introduction: Proteins are high molecular mass complex biopolymer of a-amino acids present in all living cells.

The human body breaks down protein obtained from protein-rich foods such as meat, eggs, poultry, dairy products, some vegetables, into their basic amino acid monomers. The body then uses these amino acids to build proteins essential for the various bodily functions.

The human body require twenty essential amino acids of which it can manufacture eleven by itself using the amino acid from the supplied food. The rest of the proteins is obtained directly through protein-rich foods.

Conclusion:

Protein-rich foods such as meat, eggs, poultry, dairy products, some vegetables, provides the essential compounds, that is amino acids, that the human body needs to build proteins.
