Proteins are essential for building and repairing tissues, such as muscles, bones, skin, and hair.

Leucine is an essential amino acid, meaning that it cannot be synthesized by the body and must be obtained from food.

Catabolism is the process by which proteins are broken down into amino acids, which can then be used for energy or to build new proteins.

Insulin is a hormone that stimulates protein synthesis, which is the process by which new proteins are made.

Peptide bond formation is the process by which amino acids are linked together to form a protein.

Hemoglobin is a protein that is responsible for transporting oxygen in the blood.

Collagen is a protein that provides structural support to tissues, such as bones, tendons, and ligaments.

Alanine is the most abundant amino acid in the human body.

Renaturation is the process by which proteins are folded into their functional shape.

Enzymes are proteins that catalyze chemical reactions in the body.

Denaturation is the process by which proteins are unfolded and lose their structure.

Leucine is known as the "limiting" amino acid because it is the amino acid that is most often limiting in the diet and can limit protein synthesis.

Aggregation is the process by which proteins are aggregated into larger structures.

Transporters are proteins that are responsible for transporting molecules across cell membranes.

Precipitation is the process by which proteins are precipitated out of solution.
