1.
Explain how a protein's unique three-dimensional shape is formed.
A protein’s unique three-dimensional shape is formed when individual amino
acids are bound to the central carbon atom along with the carboxylic acid group
and a carbon side chain.
2.
Explain the differences between high-quality proteins and low-quality
proteins. Which food sources provide high-quality proteins?
High quality protein contains all of the essential amino acids, has extra amino
acids available for nonessential amino acid synthesis and has good digestibility.
Low quality proteins would lack any of the essential amino acids. Animal proteins
such eggs, dairy products and meat serve all of the high quality protein
requirements.
3.
What is the RDA for dietary protein intake? What are the currently
recommended protein intakes for athletes? Is protein supplementation
required for athletes? Discuss why or why not.
The RDA for protein intake is 0.8 grams of protein per Kg of bodyweight. The
current recommendation for athlete’s is 1.2 to 2.0 g/kg. It is also recommended
that athletes spread their protein intake out through the day in doses of 20-30
grams at a time which has shown to be more effective in promoting muscle
protein synthesis. Because of the increased need for protein synthesis, athletes
need to supplement doses of protein based on their nutritional needs and training
plan.
4. Describe pre- and postexercise protein intake practices and
recommendations.
