Document Summary
As grass gets tall, it becomes lignified, which reduces nutrient quality and content. Sometimes carbohydrates and fat are combined to form one nutrient and, then there are only five different classes of nutrients. Fat is two and a half times more energetically dense than carbohydrates. Protein is for cell replication not for energy: however, protein can contribute in a minor way to the energy pool. Vitamins and minerals are cofactors for enzymes (it helps the enzymes works), metabolism, immune function, and general body function. Digestion begins in the mouth with mechanical digestion/mastication. Prehension taking food into the mouth. There are three types of digestion: mechanical, enzymatic, fermentative. No digestion occurs in the esophagus: there are two types of peristalsis that move food from the mouth into the stomach.
