equation, if pH of a solution is less than pKa, then the amino acid consists of primarily of next most protenated form, where as when the pH of the solution is greater than the pKa, then the amino acids consists of primarily of next most deprotenated form. If the pH of the solution equals that of a pKa, then the amino acid consists of 50% of next most protenated and 50% of next most deprotenated form. The ionization of the amino acid wholly depends on the pH of the solution that they are dissolved

The purpose of the experiment was to extract, purify and identify pigments from spinach leaves (including chlorophyll a, chlorophyll b and beta carotene). The experiment also compared and contrasted two different methods of separation. The first part of the experiment explored column chromatography and the second part explored thin-layer chromatography. Introduction: (3 marks)* The three pigments that can be extracted from spinach (chlorophyll a, chlorophyll b and beta carotene) all differ based

Stardust is the NASA spacecraft that took samples of the Wild 2 comet. This craft returned samples that showed sampled of glycine, an amino acid used to make proteins. The mission took place in January of 2004 and the data was sent back to Earth in January 2006. These results were the first to prove that there are life ingredients in space. This proof restarts the issue of whether our species was created by a meteor or comet that came to Earth and left these similar samples. It’s perfectly

lemon water everyday and you’ll reduce your body’s overall acidity. Lemon is one of the most alkaline foods around. Yes, lemon has citric acid but it does not create acidity in the body once metabolized.2. Balances pH: Drink lemon water everyday and you’ll reduce your body’s overall acidity. Lemon is one of the most alkaline foods around. Yes, lemon has citric acid but it does not create acidity in the body once metabolized. 3. Helps with weight loss: Lemons are high in pectin fiber, which helps

bodies do the repairs we need to and these foods contain one important thing we need and that’s protein. They can be good but too much or too little can have some impact on our body repairs. Proteins are basically building blocks called “Amino acids” which contain 20 or more essentials that come together to help repair the body’s damages. According to our text “proteins are essential to every cellular function” (Moore 166). These proteins come in essentials and non-essentials which the essentials

* * * Proteins * Proteins are complex molecules, chains of amino acids are proteins. Proteins are responsible for regulating our organs and body tissues, we must have them in order for our bodies to have structure and for our bodies to function properly.20 different amino acids work together to form a particular protein. The National Institute of Health shares that “The sequence of amino acids determines each protein’s unique 3-dimensional structure and its specific function” (nih

Acid-Base Properties of Amino Acids by IKENNA C. IKERI 02/23/2011 Chem 221 LACC Prof. Elaine Carter Definition: Amino acids are zwetterions. They form this from the intramolecular transfer of ions. H from the –COOH group is transferred to the –NH2 group to form a dipolar ion, an ion that has one (+) charge and one (-) charge. This makes the amino acid, a neutral dipolar ion also known as zwitterions. The net charge of an amino acid molecule
