It explains the importance of proteins in bodily functions, their classification into simple, conjugated, and derived proteins, and highlights the consequences of protein malnutrition such as kwashiorkor and marasmus. Protein metabolism refers to the breakdown, synthesis, and utilization of proteins and amino acids in the body. How does one group of molecules perform such a different set of functions? The amount and type of amino acids found in a protein and the sequence in which they are arranged in the polypeptide chains is a unique characteristic of each protein. Amino acids share common structure: All 20 amino acids are α-amino acids with a common structure. Each amino acid has a carboxyl group and amine group attached to the primary carbon (the α-carbon). 2 change in the 260/280 ratio.

Proteins are the most abundant and diverse molecules found in living cells. In this chapter, we begin the study of proteins by learning about their constituents, the amino acids. The details related to the structure of each of these different proteins are included in the Nutritional Biochemistry Course, Unit 2. Papers published in JBC can therefore fall under the umbrellas of not only biological chemistry, chemical biology, or biochemistry, but also allied disciplines such as biophysics, systems biology, RNA biology, immunology, microbiology Life is the result of the chemical activity of proteins (with nucleic acids essentially confined to encoding and producing them) Quaternary structure: results from the aggregation (combination) of two or more polypeptide subunits held together by non-covalent interaction like H-bonds, ionic or hydrophobic interactions. They differ from each other in terms of side chain or R group (Figure 32. 2.
