BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The human -amylase is a classical calcium-containing enzyme composed of 512 amino acids in a single oligosaccharide chain with a molecular weight of 57.6 kDa (88). The protein contains 3 domains: A, B, and C (Figure 1).

Detailed explanation-2: -While many separate enzymes are needed to interact with the food we eat, there are three amylase, protease, and lipase which are associated with the primary macronutrients in our diet; carbohydrates, proteins, and fats respectively.

Detailed explanation-3: -They belong to glycoside hydrolase family 13. Because it can act anywhere on the substrate, -amylase tends to be faster-acting than -amylase. In animals, it is a major digestive enzyme, and its optimum pH is 6.7–7.0. In human physiology, both the salivary and pancreatic amylases are -amylases.

Detailed explanation-4: -In the digestive systems of humans and many other mammals, an alpha-amylase called ptyalin is produced by the salivary glands, whereas pancreatic amylase is secreted by the pancreas into the small intestine.
