IPublished methods for the determination of plasma triglycerides are of two kinds, enzymatic (1-3) and colorimetric (4-7). Both require preliminary removal of phospholipids and saponification of triglycerides. With the enzymatic method, glycerin released is quantitatively determined with the specific enzyme GPDH’ and NAD. In the colorimetric methods, glycerin is oxidized to formaldehyde with pe...
Colorimetric recognition and sensing of sulfite by melamine-modified gold nanoparticle is reported, using Tris-HCl as the operating buffer. Furthermore, indirect determination of hypochlorite is accomplished by its oxidation of sulfite.
1. The conditions required for sensitive and specific colorimetric determination of proline with acidified ninhydrin were investigated. 2. A method applicable to protein samples was developed. 3. The only compound found to interfere appreciably was a hydroxyproline.
