Protein Flashcards
Proteins are made up of-
Amino Acids
Proteins can serve in-
Transport, storage, or membranes
There are how many distinct amino acids?
20
Enzymes are a type of-
Protein
Enzymes are catalysts in-
biochemical reactions (like digestion)
Proteins have different-
Shapes and molecular weights
Antibodies, enzymes, muscle proteins, and proteins in the skin are all made up of-
Amino Acids
What are non-essential amino acids?
Amino acids that the body produces.
How many non-essential amino acids are there?
11
Essential amino acids are amino acids that the body-
Doesn’t produce itself
How many essential amino acids are there?
9
What is used to prioritize protein sources by applying a score (up to 100) based on digestibility and amino acid variety?
PDCAAS (Protein-Corrected Amino Acid Score)
When observing the PDCAAS, the higher the score-
The more digestible and diverse the amino acids in the food source
What are some things that contain complete proteins?
Eggs, tuna fish, peanut butter, almonds, etc.
What are some things that contain incomplete proteins?
Spinach, beans, wheat germ. (Most plant-based proteins)
How much of the body is made up of protein?
8-15%
Meat, poultry, fish, eggs, and milk products are all considered-
Complete proteins
A complete protein has a low PDCAAS score.
True or false?
False, they have a high score
A incomplete protein has a low PDCAAS score.
True or false?
True
Complimentary Proteins=
Food sources that work together to provide all essential amino acids
Does the body store excess amino acids?
No, so it’s vital that our body gets all of the amino acids needed every day.
What proteins serve as the scaffolding of the body and are therefore important for the structure of tissues?
Collagen, Elastin, Fibrin, and Keratin
Enzymes do what to chemical reactions?
They catalyze them (speed them up)
Substrates =
Substances on which enzymes act
