Why some triglycerides are in liquid form while others are in solid form at room temperature? Introduction: The lipids are non-polar hydrophobic molecules that include phospholipids, waxes, oils, steroids, and fats which make up the biological membranes. Structurally and functionally, the lipids are a diverse group of compounds. They are defined by their nature of insolubility in water.

Expert Solution & Answer

Explanation of Solution

Triglycerides are the simple lipids that have three fatty acids joined with one molecule of glycerol. The triglycerides are hydrophobic. Since the fatty acids in the triglycerides possess the maximum possible amount of hydrogen, they would be called as saturated fats. In the saturated fatty acids, all bonds present between the carbon atoms in the hydrocarbon chain possess single bonds. They are relatively straight molecules and are able to tightly pack together. This makes the triglycerides to remain in a solid-state at room temperature. The molecular structure of unsaturated fats makes them liquid at room temperature. In unsaturated fatty acid, the hydrocarbon chain possesses one or more double bonds between the carbon atoms. The double bonding between the carbon atoms results in kinks that prevent them from tight packing. Thus, they have relatively lower melting point.

Older adults have unique challenges in terms of their nutrient needs and physiological changes. Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply. Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.

When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.
