Study Notes
Protein Digestion and Absorption
- Hydrochloric acid denatures proteins, breaking their complex structures, while protease breaks down proteins into smaller peptides and amino acids in the stomach.
- The combination of hydrochloric acid and protease enables the efficient digestion of proteins in the human body.
Protein as a Fuel Source
- Protein is a secondary fuel source for the body, providing energy when carbohydrates and fats are not available.
- The body can convert protein into glucose or ketones to meet energy demands.
Essential Amino Acids
- Humans require essential amino acids from their diet, as they cannot be synthesized by the body.
- A diet lacking essential amino acids can lead to protein deficiency, poor growth, and impaired health.
Characteristics of Protein
- Amino acids are the building blocks of body tissue, and a defining characteristic of protein from a nutritional standpoint.
- There are 20 different amino acids that the body uses to build proteins, with 9 being essential amino acids.
Essential Amino Acids Requirement
- Humans must obtain 9 essential amino acids from their diet, as they are not synthesized by the body.
