Proteins are biological polymers constructed from amino acids joined together to form peptides. These peptide subunits may bond with other peptides to form more complex structures. Multiple types of chemical bonds hold proteins together and bind them to other molecules. Take a closer look at the chemical bonds responsible for protein structure.
The most obvious way to reduce the shortage of food is to reduce population which seems like a long term effort however science has enables us to develop certain ways that could be used to reduce the shortage of food. We are familiar with the term genetically modified plants and animals.
