Read this article to learn about the qualitative and quantitative tests for amino acids and proteins. There are six tests for the detection of functional groups in amino acids and proteins. The six tests are: (1) Ninhydrin Test (2) Biuret Test (3) Xanthoproteic Test (4) Millon's Test (5) Hopkins-Cole Test and (6) Nitroprusside Test. We divide the food we consume [...]
This article provides a note on protein structure. Proteins can occur in four structures such as: (1) Primary Structure (2) Secondary Structure (3) Tertiary Structure and (4) Quaternary structure. The primary structure of a segment of a polypeptide chain or of a protein is the amino-acid sequence of the polypeptide chain(s), without regard to spatial arrangement (apart from configuration at [...]
