Multistep Synthesis of Benzilic Acid The synthesis of several complex organic compounds follows a multistep synthesis. "Multistep synthesis" refers to the procedure in which the product of one reaction serves as the starting material in the subsequent reaction. The multistep synthesis of benzilic acid begins with a conversion benzaldehyde to benzoin through a condensation reaction. The benzoin then oxidizes into benzil‚ which undergoes rearrangement to give benzilic acid. Benzoin Synthesis * When

Once the peptide containing the signal sequence has bound to the respective receptor‚ the peptide is transferred through the lipid bilayer through the translocation channel. For example in case of 1. Endoplasmic reticulum- ER signal sequence is about 16- to 30- residues in length and they are located on the N-terminal of the protein. Two important components in targeting the protein to the ER membrane include signal-recognition particle

Extraction and analysis of two compounds from unknown solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119
