What is the difference between plant protein and animal protein?


From the perspective of protein molecules, proteins are a peptide chain (primary structure) connected by amino acids. The peptide chain forms a helix or fold (secondary structure), and further winds to form a group (tertiary structure). Various groups are combined in a certain pattern (quaternary structure). The secondary structure of plant proteins is dominated by β-sheets, while animal proteins are dominated by α-helices. From the state of protein in food, vegetable protein is often combined with carbohydrates (non-starch polysaccharides and dietary fiber), while animal protein mainly coexists with fat.
