Study Notes
Proteins
- Proteins are complex organic compounds composed of a chain of amino acids.
- They provide energy for the body and are an important component of every cell.
- Hair and nails are mostly made of protein.
- Proteins are used to build and repair tissues, make enzymes, hormones, and other body chemicals.
- They are an important building block of bones, muscles, cartilage, skin, and blood.
Macronutrients and Micronutrients
- Protein is a macronutrient, meaning the body needs relatively large amounts of it.
- Unlike fat and carbohydrates, the body does not store protein and therefore has no reservoir to draw on when it needs a new supply.
- Vitamins and minerals are micronutrients, needed in only small quantities.
Amino Acids and Protein Types
- Proteins are made up of 20 different amino acids that join together.
- Some amino acids cannot be made by the body and are known as essential amino acids.
- It is essential that the diet provides these essential amino acids.
Measuring Total Protein
- Serum total protein is a biochemical test for measuring the total amount of protein in blood plasma or serum.
- Protein in the plasma is made up of albumin and globulin.
- Globulin is made up of α1, α2, β, and γ globulins.
- The total protein test is a faster and cheaper test that estimates the total of all fractions together.
- Other methods for measuring total protein include the Kjeldahl method, dye-binding, and refractometers.
