By: Jayquan S Salmond Out of all the amino acids‚ 8 are classified as essential amino acids. The body finds it hard to combine them with other compounds at a normal level to assist in adequate growth. The 8 are known as phenylalanine‚ valine‚ threonine‚ tryptophan‚ isoleucine‚ methionine‚ leucine‚ and lysine. When the isoleucine‚ leucine‚ and valine are grouped they are called BCAA or branched-chain amino acids. 1/3 of the body’s skeletal muscles are made up of BCAA. Skeletal muscles are

Percent Acetic Acid in Vinegar Introduction: Acetic acid is reactive when combined with calcium carbonate. In this lab‚ we will use vinegar for its acetic acid and egg shells for their calcium carbonate. Marketable vinegar differs in its acetic acid concentration from 4-6%. Calcium carbonate reacts with the acetic acid in vinegar to produce carbon dioxide‚ water‚ and calcium acetate as represented by the equation: CaCO3 + 2HC2H3O2 CO2 + H2O + Ca(C2H3O2)2. The calcium carbonate reacts with

Experiment 2: Centrifugation Title Centrifugation of fresh milk and Acetic Acid Objective(s): 1. To separate coagulated milk from mixture of fresh milk and Acetic Acid by centrifugation 2. To determine the relationship of speed of centrifugation with the coagulation of milk which separate from mixture. 3. To study the process of centrifugation Introduction Centrifugation is a process which materials suspended in a liquid medium undergo separation or concentrate due to the effect of gravity

Chemistry Laboratory I Acid Base Review Definition In general‚ an acid is a substance that can donate a proton (H+) and a base is a substance that can accept a proton. Any proton in an organic molecule can potentially be donated. The most acidic proton in a molecule would be donated first. Any lone pair in an organic molecule can act as the proton acceptor. An acid (HA) reacts with a base (in this case H2O) to form the conjugate base of the acid (A-) and the conjugate acid of the base (H3O+).

BUTENEDIOIC ACID PRE-LAB ASSIGNMENT 1. Maleic acid is the cis version and fumaric acis is the trans version of butenedioic acid. 2. 3. See attached paper. 4. Maleic anhydride is the compound that crystalizes in part A in the experiment. 5. HCl acts as a catalyst to break one of the carbonyl group in the maleic acid which rotates the structure to form a trans structure of the butonal acid which is the fumaric acid. And it does so by donating its protons. 6. Maleic acid Chronic

Protein and Amino Acid Supplementation in Sports The popularity of increasing the “performance-enhancing” supplements‚ Protein and amino acids‚ has flourished among all athletes. This increase is attributed to the belief by many of the athletes that it provides endurance‚ strength and speed enhancement. Amino Acids (AA) enhanced physical feats‚ improved energy and recovery sooner from fatigue. The three vital Amino Acids which were given a high focal point among athletes are leucine‚ isoleucine

Also known as: ethanoic acid‚ Glacial acetic acid‚ Ethylic acid‚ Vinegar acid‚ Acetic acid‚ glacial‚ Methanecarboxylic acid‚ Acetasol‚ Essigsaeure Molecular Formula: C2H4O2 Molecular Weight: 60.05196 Acetic acid is a weak acid which is probably most famous for being the primary acid in vinegar. In fact‚ acetic acid has a wide range of uses beyond sprinkling on salads‚ and it is produced in large volumes all over the world. People have been working with this acid in a number of contexts for

#04: Synthesis of Salicylic Acid from Wintergreen Oil I. Introduction and Purpose Until 1874 commercial salicylic acid was synthesized entirely from natural wintergreen oil. In this experiment the salicylic acid is reproduced using methyl salicylate‚ the major constituent of wintergreen oil and later compared to salicylic acid made from benzene. The purpose of this lab is to determine the difference between salicylic acid made from methyl salicylate and salicylic acid made from benzene comparing

ethanoyl chloride or acyl chloride‚ is an acid chloride derived from acetic acid. It belongs to the class of organic compounds called acyl halides. It is a colorless liquid. Acetyl chloride does not exist in nature‚ because contact with water would hydrolyze it into acetic acid and hydrogen chloride. In fact‚ if handled in open air it gives off white smoke owing to the hydrolysis from the moisture in the air. The "smoke" is actually small droplets of hydrochloric acid formed by hydrolysis. http://www
