identify the presence of macromolecules in certain solutions. As in our daily lives‚ macromolecules are the essential nutrients that we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and nucleic acid. They are mostly made up of hydrogen‚ carbon‚ oxygen‚ nitrogen‚ sulphur and phosphorus. 1.

The leaves contains twice the amount of protein and quadruple the amount of calcium on milk‚ quadruple the amount of Vitamin A on carrots‚ seven times the amount of Vitamin C on oranges and quadruple the amount of potassium on bananas and other nutrients. In addition‚ the leaves are comprised of numerous distinguished amino acids (i.e. sitosterol and pectin esterase). Moreover‚ the trees’ flowers‚ leaves

4 Titration Curve of an Amino Acid pH Simple amino acid Acidic amino acid Basic amino acid 7 OH- equivalents Objectives: A) To determine the titration curve for an amino acid and B) to use this curve to estimate the pKa values of the ionizable groups of the amino acid and the amino acid’s pI. Introduction: A titration curve of an amino acid is a plot of the pH of a weak acid against the degree of neutralization of the acid by standard (strong) base. Consider the ionization

Topic: Protein Folding and Molecular Chaperones - What happens when proteins fold incorrectly? Consequences of Protein Misfolding Vina Ong 20554965 Section: 126 Ares Rao A protein is made of amino acids that supply cells with their formation and execute most of their activities. Proteins can easily be denatured and refolded which happens spontaneously as the denaturing solvent is added and removed‚ under the proper circumstances. (Alberts‚ 2014) Since they can be easily denatured there

Vol. 21 Summer 2005 Newborn Screening in the 21st Century From the Editors and Authors: Since our last Update on Newborn Screening in 1998‚ there has been significant expansion of newborn screening programs in various regions of the country‚ mostly to include metabolic disorders identifiable by tandem mass spectrometry. States in our region are just now starting to expand their programs. The Summer 2005 Genetic Drift provides an update on newborn dried blood spot screening (NBS). Specifically

constituents of many cells and their contents. Carbohydrates are tests by using Molisch’s test and Benedict’s test. Molisch ’s test is a sensitive chemical test for the presence of carbohydrates‚ based on the dehydration of the carbohydrate by sulphuric acid to produce an aldehyde‚ which condenses with two molecules of phenol‚ resulting in a red- or purple-colored compound. Benedict ’s test allows for the detection of the presence of reducing sugars (sugars with a free aldehyde or ketone group). All

WGU GRT 1 Task 2 Melissa Robinson March 21‚ 2015 A1. Threonine is an essential amino acid that is classified as slightly polar due to its hydroxyl group and the ability to easily donate a hydrogen atom. This as well makes it hydrophilic and often will saturate the outer region of a water soluble protein. They hydroxyl side chain can undergo glycosylation by adding saccharides and phosphorylation by adding phosphate through the actions of threonine kinase (New World Encyclopedia‚ 2015). B.
