Amino acids are the building blocks of proteins. They band together in chains to form the stuff from which your life is born. Think of amino acids as Legos for your life. It’s a two-step process: Amino acids get together and form peptides or polypeptides. It is from these groupings that proteins are made. And there’s not just one kind of amino acid. A total of 20 different kinds of amino acids form proteins. The kinds of amino acids determine the shape of the proteins formed. Commonly recognized

Comparison of Three Isomers of Butanol SCH 4UI Abstract The Hydroxyl group on alcohols relates to their reactivity. This concept was explored by answering the question “Does each alcohol undergo halogenation and controlled oxidation?” . Using three isomers of butanol; the primary 1-butanol‚ the secondary 2-butanol and the tertiary 2-methyl-2-propanol‚ also referred to as T-butanol‚ two experiments were performed to test the capabilities of the alcohols. When mixed with hydrochloric acid in a glass test

Ban Trans-Fat Although fats are considered to be a part of our health‚ there are certain types that should be ignored. One of which has drawn controversial issues is trans-fat. Trans-fat is mostly found in many food sources such as vegetable oil‚ crackers‚ cookies and margarine. It increases blood levels of low density lipoprotein that is considered to be bad cholesterol‚ and decreases level of good cholesterol‚ high density lipoprotein. Trans-fat is created when oils are partially hydrogenated

Stereochemistry of Butenedioic Acid Objective: To study the interconversion of two geometric isomers‚ maleic acid (cis isomer) to fumaric acid (trans isomers)‚ the differences in physical properties between this pair of cis-trans isomers and determine the stereochemistry of addition of bromine to butenedioic acid. Chemicals and Apparatus: 2 grams of maleic acid‚ 10 cm3 of concentrated hydrochloric acid‚ 10 cm3 of bromine water[1]‚ one 50 cm3 beaker‚ one 100 cm3 beaker‚ one 250 cm3

Essay 2 Should We Institute a State-wide Ban of the Use of Trans Fat? Trans fats are a type of fat often used in preparation of fried foods in order to enhance the flavor and‚ in some cases‚ increase the shelf life of a product‚ but these inexpensive‚ artificially produced fats have been liked to heart disease because they increase levels of bad cholesterol in the body while lowering levels of good cholesterol and that is why I agree that we should ban the use of trans fats in New

density of states and detonation properties of trans and cis configurations of azocubane. All properties have been obtained using the B3LYP functional and 6-31G(d‚p) basis set. Also‚ IR‚ UV-Vis‚ CD and NMR spectra of the structures were simulated. The volumes of the structures computed to get the densities of the molecules. All calculations carried out in gas phase at temperature 293.15 k and pressure 1 atm. The simulation results revealed that the trans configuration of azocubane exhibits more stability
