1. Inversion may be done by acid hydrolysis or by adding an enzyme, invertase. 2. Kappa particles are Feulgen-positive and stain with Giemsa after acid hydrolysis . 3. "beta "-Hydroxybutyrate can be extracted from poly ( 3-hydroxybutyrate ) by acid hydrolysis . 4. Proteins were found to yield amino acids after enzymatic digestion or acid hydrolysis . 5. Acid hydrolysis of calcium monosilicide ( CaSi ) produces ( SiH 2 ) x.6. These DNP-amino acids are moderately stable under acid hydrolysis conditions that break peptide bonds. 7. They were printed on acid paper and were thus subject to " acid hydrolysis ." 8. However, some proteins are resistant to acid hydrolysis . 9. Strong mineral acids can readily hydrolyse the peptide bonds in a protein ( acid hydrolysis ). 10. Acetal resins are sensitive to acid hydrolysis and oxidation by agents such as mineral acids and chlorine.
