Explain the effect of motor reaction in a dc generator. 12. Explain the causes of armature losses. 13.
There are three main types of fat in food: saturated, monounsaturated, and polyunsaturated. Other types of fat are cholesterol and fats formed during processing of unsaturated oils (hydrogenated fat and trans-fat).Saturated Fat. The saturated form of fat is usually solid at room temperature.onounsaturated Fat. Monounsaturated fats appear to lower bad cholesterol levels in our blood while increasing good cholesterol. Olive oil is one of the richest sources of monounsaturated fat. Other food sources are canola or peanut oil; margarines made from olive, canola, or peanut oil; and nuts and seeds.
Monounsaturated fats are found in olive oil, peanut oil, canola oil, avocados, nuts and seeds. Polyunsaturated fats are found in many vegetable oils, including safflower, corn, sunflower, soy and cottonseed oils, as well as in nuts and seeds.
