Definitions:

Carbohydrate

Organic compounds, consisting of carbon, hydrogen, and oxygen, that are broken down to release energy in the human body, including sugars, starch, and fiber.

Daily Caloric Intake

The total amount of calories a person consumes in a day, which can vary based on age, gender, activity level, and weight management goals.

Protein

Macromolecules consisting of long sequences of α-amino acids [H2N-CHR-COOH] in peptide (amide) linkage (elimination of H2O between the α-NH2 and α-COOH of successive residues). Protein is three-fourths of the dry weight of most cell matter and is involved in structures, hormones, enzymes, muscle contraction, immunologic response, and essential life functions. The amino acids involved are generally the 20 α-amino acids (glycine, l-alanine) recognized by the genetic code. Cross-links yielding globular forms of protein are often effected through the 2SH groups of two sulfur-containing l-cysteinyl residues, as well as by noncovalent forces (such as hydrogen bonds, lipophilic attractions).

Carbohydrate Reserves

Stored sugars and starches in the body, primarily in the liver and muscles, used as a source of energy.
