Protein combining (or protein complementing) is a dietary theory for protein nutrition that purports to optimize the biological value of protein intake. According to the theory, vegetarian and vegan diets may provide an insufficient amount of some essential amino acids, making protein combining with multiple foods necessary to obtain a complete protein. The terms complete and incomplete are outdated in relation to plant protein. The position of the Academy of Nutrition and Dietetics is that protein from a variety of plant foods eaten during the course of a day supplies enough of all essential amino acids when caloric requirements are met.

A method for improving the accuracy of determining the content of malondialdehyde in a biological sample
The application discloses a method for improving the determination accuracy of the content of malondialdehyde in a biological sample, which comprises adding a buffer solution, a protease solution and a thiobarbituric acid (TBA) into a malondialdehyde standard solution, and determining the absorbance of the malondialdehyde standard solution; subsequently, a standard curve is constructed, and the actual concentration of the malondialdehyde in the biological sample is calculated through the measured absorbance of the biological sample solution. The sample processing process of the method is simple, the Buffer A buffer solution and the protease used can release the MDA combined with the protein, can not only avoid the adsorption interference of the protein precipitation on the red complex of the MDA and the TBA and the extraction limitation of the supernatant, but also can detect the protein combined state MDA, can significantly improve the detection limit of the sample, is good in selectivity, improves the accuracy of the detection result, and can be used for the trace detection of clinical precious samples.
