Study Notes
Primary Role of Proteins
- Proteins are essential macromolecules that perform a variety of functions in the body, including building and repairing tissues.
- They play a crucial role in the formation of enzymes and hormones, supporting metabolic processes and homeostasis.
- Proteins also contribute to muscle growth, immune responses, and transportation of molecules within cells.
Sources of Dietary Proteins
- Common sources of dietary proteins include meat, fish, dairy, legumes, and nuts.
- Plant-based foods like soy, quinoa, and lentils serve as excellent protein sources.
- Example of a non-source: refined sugars or starches do not provide dietary protein.
Building Block of Proteins
- Amino acids are the fundamental building blocks of proteins, consisting of a basic structure containing an amino group, carboxyl group, and a unique side chain.
- There are 20 different amino acids, nine of which are essential and must be consumed through diet.
Protein Synthesis Process
- Protein synthesis primarily occurs through a process called translation, where ribosomes create proteins by reading messenger RNA (mRNA).
- This process follows transcription, where DNA is converted into mRNA.
Effect of Extreme Heat on Proteins
- Proteins can denature when exposed to extreme heat, resulting in the unfolding and loss of their functional shape.
- Denaturation can lead to the loss of biological activity, affecting the protein's ability to perform its necessary functions.
