Branched-chain amino acids

of Macromolecules Using Benedict’s, Biuret’s, Sudan III, and Lugol’s Solution Betty Ngo Introduction Macromolecules are the critically important large molecules that fall into four main classes: carbohydrates, lipids, proteins and nucleic acids. Macromolecules are polymers which are built up by monomers. Monomers become polymers from the process dehydration reaction and polymers are broken apart by the process hydrolysis. Macromolecules are critically important to all living organisms…

The borax is acting as the crosslinking agent or "connector" for the glue (polyvinyl acetate) molecules. A cross-link is a bond that links one polymer chain to another. They can be covalent bonds or ionic bonds. "Polymer chains" can refer to synthetic polymers or natural polymers (such as proteins). Once the glue molecules join together to form even larger molecules called polymers, you get a thickened gel very similar to slime. Below is…

In a biochemical reaction, enzyme which are proteins based compounds are used as a catalyst to produce a high yields. Proteins are the macromolecular components of almost enzymes, except for ribozymes, a class of RNA modifying catalysts. Enzymes are classified on the basis of their composition; simple enzymes are those composed wholly of proteins, whereas, complex enzymes which also known as haloenzymes, composed of protein plus a relatively small organic molecule. In this terminology the…

Unit 2 Project In your own words Discuss why carbon is essential to life on Earth. (150 word minimum response) Carbon is a vital element in organic compounds. Organic compounds are compounds that are usually located in living things.Organic compounds are very vital and Carbon is an elemnt that makes up organic compounds. Carbon helps organic compounds make up cells and carry out important life functions.Additionally, carbon can form strong bonds with itself and many other elements. This…

the human body. Proteins are necessary to the survival of humans because without them humans would seize to exist. A protein is a large molecule that consists of multiple amino acids subunits, which are joined together by peptide bonds. When one consumes food, which contains proteins, it is broken down into its separate amino acid molecules, which can then be used by the body to form other proteins (8). Proteins aid the human bodies, not only in growth, but they also help with tissue repair, and…

through the hair follicle and towards the surface of your scalp, it is known as keratinization. Keratin is rich in sulfur protein. Most of your hair is made of proteins (amino acids). Amino acids are made up of theses elements; Carbon, Oxygen, Hydrogen, Nitrogen and Sulfur also known as side bonds.These elements help link the amino acids together and…

proteins. For the first part, you must observe egg albumin solution before heating and what happen to the solution after heating. Second part, first placed 3 ml of egg albumin solution in a test tube and carefully add 20 drops of concentrated nitric acid, while holding the test…

Report on Result and Discussion on isolation of protein from spinach leaves In this experiment, we tried isolating an actual protein called Rubisco from spinach leaves. The full meaning of these Rubisco means Ribulose-1, 5-bisphosphate carboxylase/oxygenase which is an enzyme that catalyzes the addition of a carbondioxide group to ribulose-1, 5-bisphosphate during sugar production in green plants. Although Rubisco is an abundant protein in plants, it is not the major component in all spinach…

bicomponent toxin with 30% amino acid sequence identity to the other known leucocidins. This novel leukocidin was named LukHG, where LukH refers to the S subunit and LukG refers to the F subunit (Ventura et al, 2010). Around the same time, during proteomic studies by DuMontetal to identify a novel leukocidin responsible for lytic activity on S. aureus culture supernatants derived from bacteria grown in Roswell Park Memorial Institute medium enriched with Casamino Acids (RPMI-CAS), LukAB toxin…

Biology Matching Terms DNA- is the replication of your parents and ancestors genes RNA- is the transcription of dna, ribonucleic acid; guides protein synthesis. Translation- process in which RNA is synthesized from the template DNA. Transcription- process in which RNA attaches to the ribosome and a protein is assembled. Replication- method of DNA replication in which parental strands separate, act as templates, and produce molecules of DNA with one parental DNA strand and one new DNA strand.…
