Protein Synthesis

Protein Synthesis

Protein synthesis is the process whereby proteins are produced , or synthesized , in living things according to "directions " given by DNA (deoxyribonucleic acid ) and carried out by RNA (ribonucleic acid ) and other proteins

Human Body

There are many applications that are being derived out of producing protein . As human being the bones of the human body are about one fourth protein , and proteins makes up a very high percentage of the material in our organs (including the skin , glands , and bodily fluids . The cells and tissue composing our body structure

is protein which promotes the growth and repairing bone , muscles , tissues , blood , and organs Observing the motions of a protein in our cells and tissue , they move molecules around within our cells to serve an array of needs and allow healthful substances , such as oxygen , to pass through cell membranes while keeping harmful ones out . During the process of eating inside the body the enzymes and other proteins have roles in digesting foods and turning the nutrients in them - including proteins - into energy

Human Health

Protein is one of the good factors in the health condition of the human body . Meat or such animal products as milk , cheese , butter , and eggs are one of the sources of proteins . A secondary group of foods that might appear on the average person 's list of proteins include peas , beans lentils , nuts , and cereal grains

Proteins are also one of the basic nutrients , along with carbohydrates lipids , vitamins , and minerals (see Nutrients and Nutrition . They can be broken down and used as a source of emergency energy if carbohydrates or fats cannot meet immediate needs . The body does not use protein from food directly : after ingestion , enzymes in the digestive system break protein into smaller peptide chains and eventually into separate amino acids . These smaller constituents then go into the bloodstream , from whence they are transported to the cells . The cells incorporate the amino acids and begin building proteins from them

According to the U .S . Food and Drug Administration (FDA , protein should account for 10 of contains 4 calories per 0 .035 oz (1 g , that would be about 1 .76 oz (50 g ) in a diet consisting of 2 ,000 calories a day . A pound (0 .454 kg of steak or pork supplies about twice this much , and though very few people sit down to a meal and eat a pound of meat , it is easy to see how a meat eater would consume enough protein in a day

For a vegetarian , meeting the protein needs may be a bit trickier , but it can be done . By combining legumes or beans and grains , it is possible to obtain a complete protein : hence , the longstanding popularity , with meat eaters as well as vegetarians , of such combinations as beans and rice or peas and cornbread . Other excellent vegetarian combos include black beans and corn , for a Latin American touch , or the eastern Asian combination of rice and tofu , protein derived from soybeans...
