  • Artificial Sweetener Aspartame
    694 words
    Artificial sweeteners can taste wonderful to your taste buds, however can be very dangerous to a persons health. Almost everything people consume today has artificial sweeteners, such as Aspartame, Stevioside, Acesulfame, and Saccharin. The artificial sweetener Aspartame (i.e. Nutrasweet), (APM) is a dipeptide. A dipeptide is when 2 amino acids are linked together (as you know, amino acids make up proteins). The 2 amino acids are phenylalanine and aspartic acid. There is a certain configuration ...
  • Specific Amino Acid To T Rna
    611 words
    6.4 Translation 6.4. 1 Explain how the structure of t RNA allows recognition by a t RNA-activating enzyme that binds a specific amino acid to t RNA, using ATP for energy. Each amino acid has a specific t RNA activating enzyme that helps t RNA to combine with its complementary m RNA codon. The enzyme has a 3 part active site that recognizes three things: . A specific amino acid. ATP, . A specific t RNA. The enzyme attaches the amino acid to the 3' end of the t RNA. The amino acid attachment site ...
  • Ribosome By A Ribosome Recognition Sequence
    563 words
    Bio Essay of Protein Synthesis There are three stages are involved in polypeptide chain synthesis. The yare chain initiation, chain elongation, chain termination. All three stages require enzymes. Initiation and elongation also require energy which is provided by GTP (a molecule closely related to ATP). In initiation several proteins and GTP take part in the complex process that initiates polypeptide synthesis. This process determines both where translation will begin and how the sequence of nuc...
  • Amino Acids To The Mrna At Ribosomes
    681 words
    Proteins are some of the most essential compounds on the planet. They perform a variety of tasks ranging from muscle contraction to fighting diseases. Over 50% of the dry weight of organisms are made of proteins; this is because things like your nails and hair are made of proteins. Proteins are also components of biological membranes, and they help regulate the passage of molecules through the membranes. This is all very important to the body, but the most important function, by far, is their us...
  • Amino Acid Side Chains
    1,776 words
    1. Describe The Devices And Processes That Govern The Creation Of A Functional Domain In Any Enzyme. When discussing enzymes, one must have an excellent understanding of proteins, because nearly all enzymes are proteins. Enzymes are proteins that carry out specific functions such as bind molecules with a high degree of specificity or carry out chemical reactions. They catalyze such chemical reactions that would control the flow of particles through membranes, control the concentration of certain...
  • C 13 To C 12 Ratio
    761 words
    I was at home minding my own business when all of a sudden and my bag got sucked back in time. I don't know or I can't explain really what occurred, but I found my self at the beginning of time itself. So I decided to make down my own thoughts and what I saw. Here is my journal entry. Date: No sure when (around 4.5 billion years ago) Time: Don't ask. There were volcanoes everywhere, there was lava pouring out from the earth in large quantities. Ash was flying around my very own head landing in m...

  • High Levels Of Folic Acid
    591 words
    The New Sensation. Before you sit down to munch on your breakfast cereal or bread, you might want to take notice of a vitamin that seems to be popping up more and more in ingredients. This is being Folic Acid. The FDA is recommending that it be added to foods and that people take it in pill form every day. This is mainly because it is a key component in the never-ending battle our body fights against diseases. What is it capable of? It is proven to lower chances of birth defects, and heart attac...
  • O Tethered Agonist At Three Selected Sites
    921 words

  • Acid's P Ka Values
    1,851 words
    Determination of An Unknown Amino Acid From TitrationAbstractExperiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96, and the p Ka " sound experimentally were 2.0, 4.0, and 9.85. The accepted p Ka values we refound to be 2.10, 4.07, and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be acid, hydrochloride. Introd...
  • Natural Sources Of Tryptophan
    1,131 words
    The only ones still awake within an hour of Thanksgiving dinner were me and the dog. The dog sat hopefully underneath the table, waiting for the weight of the food to bring the whole mess crashing down to her. I sat on the back porch and watched my family sprawled across the living room like the aftermath of an inquest. "It's the trip... tripophen... trip to something", my mom had murmured drowsily right before spreading lengthwise in front of the fire. "It makes you fall asleep. I saw it on the...
