________ require increased protein intake.

carbon skeletons

Dietary protein requirement

________ is influenced by the carbohydrate content of the diet.

Carbohydrate

________ allows amino acids to be used for repair and maintenance of tissue protein rather than for gluconeogenesis.

urinary nitrogen

When excess is eliminated from the body as ________, it is often accompanied by increased urinary calcium, increasing the risk of nephrolithiasis (kidney stones) and osteoporosis.

Protein

________ consumed in excess of the bodys needs is deaminated.

Amount of dietary protein

________ required varies with its biological value.

Protein restriction

________ may be needed in kidney disease.

Protein Quality

a measure of a dietary proteins ability to provide the essential amino acids (EAA) required for tissue maintenance

Protein Digestibility-corrected amino acid score (PDCAAS)

the standard adopted to evaluate protein quality, based upon the profile of essential amino acids and digestibility of protein

highest score

1.00

Nitrogen balance

amount of nitrogen consumed equals that of the nitrogen excreted

Positive nitrogen balance

nitrogen intake exceeds nitrogen excretion

Negative nitrogen balance

nitrogen loss is greater than nitrogen intake

recommended intake

0.8g/kg/day

daily intake of
