Essential amino acid

Proteins are complex molecules that serve a variety of functions within the body. Proteins are made up of subunits called amino acids. There are several different types of amino acids such as lysine, aspartic acid, and histidine. Each type of amino acids have their own specific group called R-groups attached to them, this causes them to behave chemically different. The group on the amino acid histidine cause the amino acid to be basic; this feature of histidine makes it have a specific purpose in proteins, such as binding other molecules or atoms to a protein and also participating in a catalytic triad. Amino acids are usually put into two different groups, essential and non-essential, and histidine is classified as an essential. The difference between these two groups depend on if the amino acid could be synthesized in the body or not. Essential amino acids are the amino acids that can not be synthesized in the body. There are nine essential amino acids. These are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine (Wax). Since histidine can not be synthesized in the body, other organisms have to synthesis it for humans to ingest…

Many of us have been programed to believe that we should eat meat 3 times a day. After all it is an essential dietary component for all living organisms. Protein is an organic compound consisting of chains of amino acids that are important for the body in terms of hair, collagen, tissue, and muscles. Without consuming the proper amount of protein, our bodies can’t function properly. That is why American are so edge about not having enough of it. However, a recent infographic released by Door…

I. Introduction A. Eggs are widely known as a functional food because they are high in protein, modest in calories, low in cost and can be used versatilely in many different types of dishes1. They represent a complete food, meaning it contains all nine of the essential amino acids necessary for dietary needs2. Egg composition may vary slightly, but on average the macronutrient content of one egg is low in carbohydrates and high in proteins and lipids2. High protein foods, like eggs, have been…

children, bringing about bone deformities. Lack of Vitamin D, phosphorus or calcium are the most common causes of this condition. Symptoms can include; skeletal pain, skeletal deformities such as “bowed legs” or curvature of the spine. There is also a high chance of bone fracturing. Vitamin D is the most common cause and is essential for the absorption of calcium in the gut. The main source of Vitamin D comes from natural sunlight where the sun’s ultraviolet light allows the body’s skin cells…

vegetarianism is good for one’s health tends to be a controversial topic, as meat contains more essential nutrients than vegetables. Meat provides a higher-quality source of protein than vegetables because meat is packed with amino acids that vegetables do not supply. The type of iron in meat also absorbs better than vegetables which contributes to low iron levels in vegetarians. Due to these facts many believe that vegetarianism is not a good practice and will not provide the right amount of…

She asked numerous questions, which often involved repetition. However, when my mother came to visit, we watched the documentary, Cowspiracy (Anderson & Kuhn, 2014), and just as I did, my mother immediately became a vegan. What a relief to vent about everyday struggles vegans face with both my mother and husband. For example, when dining at restaurants, and asking for no cheese and no chicken, the server usually inquires, “well, what would you like for your protein then?” Ok, let us revisit…

I just realized after having a conversations with some of my friends on campus that I considered fish as the major source of this essential amino acids. I tend to like grilled fish not fried fish so I realized that tuna salad was the only way I had fish and was worried that I was not getting this amino acids. After doing a research and realizing that fish is just one type of meat that has omega 3 amino acids, I made it my goal to not worry about not eating fish but try and eat the kinds of…

sources. Proteins are considered a key source that is needed in the human body and are essential to one’s diet. This is true because proteins inhabit a spot in every cell in an individual’s body. Therefore, individual’s need to consume a large amount of protein in order to maintain good health. Proteins are essential to a variety of different functions for one’s body but are said to help with muscle growth and maintenance, bone health, and even weight management. Proteins provide the human body…

Protein in a nutrient found in the body, which is made up of carbon, hydrogen, nitrogen, oxygen, and sometimes sulphur. This is known to be the only nutrient that can give the body nitrogen. Protein is essential for life, as all cells use protein to perform their bodily functions. The body uses proteins and needs it for growth, maintenance and repair, production of enzymes, hormones and genes, and as a source of energy, only needed if the body is short on carbohydrates and fat. The elements in…

Transfer RNA Transfer RNA (tRNA) is a crucial component in Protein Synthesis. It serves as an adaptor molecule between the codon, the three nucleic acids and the amino acid after which a specific protein will be synthesized. It is the intermediate in Protein Synthesis which interprets the genetic code. Without tRNA, translation in prokaryotes or eukaryotes could not take place. Common Features of tRNA Molecule Each amino acid has at least one tRNA molecule. Therefore, these tRNA molecules have…
