próteína

Proteína is a Spanish word that translates to "protein" in English. Proteins are large, complex molecules that play many critical roles in the body. They are essential for the structure, function, and regulation of the body's tissues and organs. Proteins are made up of smaller units called amino acids, which are linked together in long chains. The sequence of amino acids determines the unique three-dimensional shape and function of each protein.

There are many different types of proteins, each with its own specific job. Some proteins, like collagen and keratin, provide structural support to the body. Others, like enzymes, act as catalysts to speed up chemical reactions. Hormones, such as insulin, are also proteins that regulate various bodily processes. Antibodies are proteins that help the immune system fight off infections. Muscles are largely composed of proteins like actin and myosin, which enable contraction.

Dietary protein is obtained from various food sources, including meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds. The body breaks down dietary proteins into amino acids, which are then used to build new proteins needed for growth, repair, and maintenance. A balanced diet that includes adequate protein intake is crucial for overall health and well-being. Protein deficiency can lead to various health issues, including muscle loss, weakened immunity, and impaired growth.
