Detailed explanation-1: -Amino acids are found in animal sources such as meats, milk, fish, and eggs. They are also found in plant sources such as soy, beans, legumes, nut butters, and some grains (such as wheat germ and quinoa). You do not need to eat animal products to get all the protein you need in your diet.

Detailed explanation-2: -Animal proteins are widely used for the formation of protein particles in the food industry, e.g., casein, whey protein, gelatin, egg proteins, and fibroin. Proteins isolated from milk are one of the most commonly used proteins from animal sources, e.g., caseins and whey proteins.

Detailed explanation-3: -Protein can come from both plants and animals, although the number and type of amino acids within them differ. Common sources of protein are red meat, poultry, fish, lentils, soy, nuts, legumes, grains and tofu.

Detailed explanation-4: -The protein in dog foods can be supplied by animal sources, plant sources, or a combination of the two. Common animal-based protein sources used in pet food include chicken, lamb, fish meal, and beef. Common plant-based protein sources used in pet food include corn-gluten meal and soybean meal.
