Peptides are the building blocks of proteins, offer many of the structures in the body – including hair, skin, muscles, tendons and ligaments. They form the hemoglobin in the blood, which carries oxygen around the body to the muscles and organs. Peptides are also the major building blocks for enzymes that catalyze chemical reactions of cellular functions, and provide the signals on the outer surface of cells can communicate their body systemically. Peptides have many uses, and most of them are necessary for life.
Silk is a chain of peptides formed in a structure called a beta-pleated sheet. Silk is strong, light and durable because of the way and the peptides bind protein folds. Silk is produced from spiders and some worms. Peptide structure is essential for the survival of organisms to catch food and protection from the elements.
Collagen has been a focus for cosmetic industries, as the cure for wrinkles. Collagen is a part of the skin that makes tight and firm as well as maintaining the appearance of wrinkles. The sun destroys collagen, causing it to die prematurely. Several companies offer collagen cosmetics products to reverse the progression of wrinkles. Moisturizing also protects collagen damage, leaving the healthier skin.
HIV is an RNA virus that infects immune cells. More specifically, T cells are infected, inhibiting the body’s ability to destroy invading microbes. Researchers at Purdue University have developed enzymes that prevent dimerization of the HIV structure. Inhibition of HIV bonds allows drugs that interfere with virus binding to cells, limiting the number of infections in people.
Peptides are the building blocks of proteins, and proteins are hemoglobin. Hemoglobin circulates oxygen within the air inhaled tissue and organs within the body. However, researchers in the USA discovered that hemoglobin also helps in protecting bacteria from entering into the body.
