Proteins.<\/p>\n<p>Proteins are essential for the contraction of muscles, digestion of food, and clotting of blood. They are made up of amino acids, which are the building blocks of proteins. There are 20 different types of amino acids, and the human body can only produce 11 of them.

They are essential for the growth and repair of tissues, the production of hormones and enzymes, and the transport of nutrients and oxygen. Proteins are also involved in the immune system, and they help to protect the body from disease.<\/p>\n<p>The three main types of proteins are structural proteins, functional proteins, and regulatory proteins. Structural proteins provide support and structure to the body, such as collagen, which is found in skin, bones, and tendons. Functional proteins perform specific tasks in the body, such as enzymes, which help to break <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> down food, and hormones, which regulate body functions.
