What does it mean if a food is a complete protein source?
A complete protein or whole protein is a food source of protein that contains an adequate proportion of each of the nine essential amino acids necessary in the human diet.
Which of the following is a result of a dietary protein deficiency?
Serious protein deficiency can cause swelling, fatty liver, skin degeneration, increase the severity of infections and stunt growth in children. While true deficiency is rare in developed countries, low intake may cause muscle wasting and increase the risk of bone fractures.
What happens if the shape of a protein is altered quizlet?
The amino acid sequence causes the polypeptide to assume a particular shape. The shape of a protein determines its specific function. If a protein’s shape is altered, it can no longer function. loses its function.
Which food is a higher quality protein?
Most animal sources of protein, such as meat, poultry, fish, eggs, and dairy, deliver all the amino acids your body needs, while plant-based protein sources such as grains, beans, vegetables, and nuts often lack one or more of the essential amino acids.
Is peanut butter a complete protein?
Although peanut butter is not a complete protein — meaning it does not contain all of the essential amino acids the body needs — it does count toward a person’s daily protein intake.
Which foods have complete proteins?
Which foods are complete proteins? Animal proteins are complete, including meat, poultry, fish, eggs and dairy. There are also a few plant-based sources of complete protein, including: Quinoa.
Which disease is caused by protein deficiency?
Based on available literature the researcher arrived at conclusion that insufficient of protein may cause various health problems such as kwashiorkor, marasmus, impaired mental health, edema, organ failure, wasting and shrinkage of muscle tissues, and weakness of immune system. 1. Rosendaal FR.
What are the signs of protein deficiency?

How do I know if I need more protein?
Swelling. One of the most common signs that you’re not getting enough protein is swelling (also called edema), especially in your abdomen, legs, feet, and hands.
What happens if the shape of a protein is altered?
Proteins have different shapes and molecular weights, depending on the amino acid sequence. … Because form determines function, any slight change to a protein’s shape may cause the protein to become dysfunctional.
How does the shape of a protein affect its function?
Protein function is directly related to the structure of that protein. A protein’s specific shape determines its function. If the three-dimensional structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.
What happens to a protein during denaturation?
When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.

Is Rice a high quality protein?
Brown Rice Protein
Protein powders made from brown rice have been around for some time, but they are generally considered inferior to whey protein for building muscle. Although rice protein contains all of the essential amino acids, it is too low in lysine to be a complete protein.
