Study Notes
Amino Acids and Proteins
- The human body cannot synthesize essential amino acids, which must be ingested through diet.
- Proteins are made up of amino acids.
Essential Amino Acids
- Essential amino acids are termed as such because they cannot be synthesized by the body and must be ingested.
- There are 8 essential amino acids.
Protein Function and Digestion
- The primary function of body proteins is to build and repair tissues.
- During digestion, proteins are broken down into amino acids.
- After digestion, the liver processes the amino acids, and the remaining amino acids are released into the bloodstream.
Amino Acid Uptake and Synthesis
- The term "amino acid surge" describes the cells' tendency to take in as many amino acids as they can to maintain their own supply.
- Amino acids that can be synthesized by the body cells are called non-essential amino acids.
- The two sources of non-essential amino acids are:
- Recycling of existing proteins
- De novo synthesis from other nutrients
Protein Synthesis
- For protein synthesis to take place, the amino acid pool must contain the necessary amino acids.
- Vegetarians must be knowledgeable about combining plant-based foods to make complete proteins, as plant-based foods often lack one or more essential amino acids.
Incomplete Proteins
- Foods that contain only limited or improper amounts of essential amino acids are called incomplete proteins.
