What is the R in protein?

The “R” groups come from the 20 amino acids which occur in proteins. The peptide chain is known as the backbone, and the “R” groups are known as side chains. Note: In the case where the “R” group comes from the amino acid proline, the pattern is broken.

What are some examples of protein?

Meat, seafood, poultry, grains, beans and dairy products are good sources of protein. Protein is a macronutrient that is essential to building muscle mass. It is commonly found in animal products, though is also present in other sources, such as nuts and legumes.

What are the 2 types of protein?

What does protein do in the body?

Protein is one of a complex group of molecules that do all kinds of jobs in your body. They make up your hair, nails, bones, and muscles. Protein gives tissues and organs their shape and also helps them work the way they should. In short, protein is one of the building blocks that make you into who you are.
