Amino Acid Lab Report

Improved Essays
Protein is the building blocks of life (nlm.nih.gov). Amino Acids are the building block of protein. Amino acids bond together to make long chains, which is protein (nlm.nih.gov). Human body uses amino acids to make proteins to help the body break down food, repair body tissue, grow, and perform many other body functions (nlm.nih.gov). Amino acids can also used as a source of energy by the body (nlm.nih.gov). According to what I learned in Bioorganic lecture, the amino acid structure contains a carboxylic acid group (-COOH) and an amino group (-NH2) bonded to the carbon atom. The scientists have discovered over 50 amino acids, however, only 20 are used to make proteins in the human body (nlm.nih.gov). Of those 20 amino acids, 9 are defined …show more content…
They are not flammable, however propanol and acetic acid can pose health risks or flammable. The ninhydrin can stain your skin purple all day if you don’t wear gloves when using it. Phenylalanine was one of the amino acid that used in the lab. It falls under the essential amino acid group. There are 3 forms of phenylalanine: D-phenylalanine, L-phenylalanine, DL-phenylalanine (m.webmd.com). Meat, fish, cheese, milk, and eggs are the major dietary sources of phenylalanine. Phenylalanine is used for depression, attention deficit-hyperactivity disorder (ADHD), Parkinson’s diseases, chronic pain, etc. (m.webmd.com). Leucine is an essential amino acid and the most important for bodybuilder. Leucine has a greater power on stimulating skeletal muscle protein synthesis than any other amino acid (bodybuilding.com). Another amino acid is Lysine. It is also an essential amino acid. People use lysine to make medicine. It helps in preventing and treat cold sores caused by the virus (m.webmd.com). Alanine is the next amino acid that used in this lab, it is a non-essential amino acid. Alanine is an important source of energy for muscles and central nervous system, increases immunity, helps in the metabolism of sugar and organic acids …show more content…
TLC is a common use because it is simple to perform, inexpensive, and high sensitivity. TLC work based on different affinities for mobile and stationary phases of a mixture and this wills affects the speed at which it moves (chemwiki.ucdavis.edu). The goal of TLC is to achieve well-defined, separated spot. After the separation is complete, each component appears as spots separated vertically. Each spot has a retention factor (Rf), which is equal to the spot distance / the distance of base line to the solvent front. The Rf value can be used to identify compounds due to their uniqueness to each compound

    Proteins are built in the ribosome, an organelle inside of a cell. Many structures such as tissues and organs are made of proteins. They are the main components of hair, skin, muscle, heat and other important organs. Many important part of a living organism depend on these to proteins to function properly. For example, athletes are often recommended to eat foods high in protein for muscle development.…

    You should get 19 milligrams per kilogram of isoleucine and 24 milligrams per kilogram of valine. Sources for BCAAs: Branched chain amino acids have become a big hit in the fitness industry. However, you can get BCAAs from many whole foods. LEAN MEATS AND POULTRY: Branched chain amino acids (BCAAs) are made up of three essential amino acids that are necessary for protein synthesis. These amino acids include leucine, isoleucine and valine and they make up about one third of the muscle in the human body.…

    Made up of nitrogen-containing molecules known as amino acids, protein plays a fundamental role in the health of our bodies. “Begin the major component of nearly every cell” (pg.262), protein has gained the nickname “body builder” because of its role in developing and repairing bones, muscles and skin, and blood cells. However, that is only a few of the functions that proteins play in our health, they are also a key elements of antibodies that protect us from disease, they regulate hormones and transport iron, oxygen and nutrients through out the entire body. The need for proteins is vital to our survival. Providing 4 calories per gram, it is, recommend from the Food Guide Pyramid that we eat 2-3 serving of proteins daily, and that we receive 10-15 % (no less the 10 no more then 15) of our calories should come from proteins.…

    Lysyl-tRNA synthetase binds to transcription factors, which can lead to allergies. It also may be a target of autoantibodies, which can lead to disease (Smith, 1998). Lysyl-tRNA synthetase is also involved in the signaling pathway, which has a direct connection to the genes in the DNA of a person. Lysyl-tRNA Synthetase has some important rules. It is important for protein synthesis, helps regulate signal molecules, and an important activator of a person’s genes in their DNA.…

    The relationship between codons and amino acids is known as the genetic code where it defines how sequences of codons specify which amino acid will be added next. Ribosomes are large structures within the cytoplasm that house the translation process and catalyze some of its steps. These structures are made up of ribosomal RNA (rRNA) and protein subunits that provide a space for tRNA to bind to an mRNA template. Each ribosome contains 3 binding sites known as the A,…

    In this series of experiments the productivity and function of the enzyme Alkaline Phosphatase will be examined. Alkaline Phosphatase is an enzyme commonly produced and found throughout the entire human body. Its main function is the cleaving of phosphate groups from mostly organic molecules, including proteins, nucleotides and even alkaloids, which makes it a hydrolase enzyme (Ellis, 2016). In biochemistry, a hydrolase enzyme is an enzyme that speeds up the hydrolysis of complex biomolecules like proteins, starch and fats (Horak, 2014). The addition and elimination of phosphate groups is an important process in biochemistry, as many enzymes are catalysed or have their activity controlled by this process.…

    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 with a multitude of functions such as messengers, enzymes, antibodies, structural components, or even transportation and storage.5 Once protein has entered the body, it is digested in the stomach and small intestines. During digestion, protein molecules are broken down into amino acids. These amino acids are produced in an individual’s body by building off other amino acids or made entirely new.1 Once an amino acid is broken down in the…
