WebbA protein may consist of a single polypeptide or more than one polypeptide linked together. The amino acid sequence determines the three-dimensional conformation of a protein. Living organisms synthesise many different proteins with a wide range of functions. Every individual has a unique proteome. WebbIn the laboratory, we can carry out certain tests to determine if the given sample has one of the key biological molecules such as carbohydrates, lipids, and proteins. The tests discussed here are qualitative in nature as they only tell us the type of biological molecule present in the sample rather than the quantitative value of the biological molecule in the …
