Protein Digestion
These two gastric substances assist with protein digestion: hydrochloric acid and this activated enzyme from pepsinogen.
What are hydrochloric acid and pepsin?
After amino acid profile, this factor—is the second most important component of protein quality.
What is digestibility?
Of heating, blending, salting, or acid-soaking, this is the one method that will NOT alter a protein's functional shape.
What is cooling in a refrigerator?
This age-related muscle-wasting condition, sarcopenia, poses a higher risk in this population group.
Who are older adults?
White blood cells secrete these proteins to protect against bacteria and viruses.
What are antibodies?
Chemical digestion of proteins begins here and ends in the small intestine.
What is the stomach?
When incomplete proteins are combined to provide all essential amino acids, they are called this type of foods.
What are complementary foods?
Both alpha helix and beta sheet belong to this level of protein structure.
What is secondary structure?
The bonds linking amino acids together to form proteins are called these bonds.
What are peptide bonds?
This structural protein is the most abundant in the human body.
What is collagen?
This protein-deficiency condition is known as kwashiorkor, while the one involving both protein and energy is this.
What is marasmus?
This strictest vegetarian diet avoids all animal products and by-products, including eggs and dairy.
What is vegan?
This scoring system measures a food's overall protein quality, correcting for digestibility and amino acid profile.
What is Protein Digestibility Corrected Amino Acid Score?
Protein deficiency can lead to swelling, irritability, skin problems, muscle wasting, fatigue, and even this ultimate outcome.
What is death?
Keratin provides structure to skin, hair, and nails, while this protein allows connective tissues to stretch and snap back.
What is elastin?
The continual breaking down and rebuilding of proteins in the body is called protein this.
What is turnover?
Foods scoring a perfect 1 on the PDCAAS scale include egg white, soy protein, whey, and this dairy component.
What is milk protein?
In equilibrium, protein input equals protein used plus this excreted amount.
What is protein excreted?
Unlike most proteins, collagen lacks this typical structure of four intertwined subunits.
What is quaternary structure?
When proteins are broken down and amino acids catabolized, this element is released as waste.
What is nitrogen?
In the small intestine, the pancreas secretes these two enzymes—trypsin and this—to continue protein breakdown.
What is chymotrypsin?
Basic amino acids are positively charged, while these are negatively charged.
What are acidic?
An adult weighing 90 kg (about 200 lbs) needs approximately this many grams of protein daily at the basic RDA level.
What is 70 grams?
The Acceptable Macronutrient Distribution Range for protein is this percentage of daily calories.
What is 10 to 35%
The simplest level of protein structure is the sequence of these building blocks.
What are amino acids?
