Exam 3: The Molecules of Life

A fat that is hydrogenated is ________.

Please read the following scenario to answer the following questions. Cooking oils,such as olive oil,are largely made up of unsaturated fats.If you have ever heated cooking oil in a pan,you might have noticed that eventually the oil begins to smoke.The temperature when this occurs is called the "smoke point." At the smoke point,the fatty acids and glycerol molecules that make up the unsaturated fats in the oil begin to break down and form smoke.Different oils have different smoke points,and these smoke points depend on the molecular composition of the oils.Below is a table with data for four different types of cooking oils,including their smoke points (values are for 1 tablespoon each [15 ml]). Type of cooking oil Calories Saturated fat () Unsaturated fat () Smoke Point Olive 119 1.9 11.4 375 Avocado 124 1.6 11.9 520 Canola 120 1.0 12.0 400 Peanut 119 2.3 10.3 450 -Which of the following statements about the data in the table is TRUE?

Enzymes are ________.

A friend of yours appears to have put on a lot of muscle very quickly.At the same time,you notice that your friend seems to have a lot of mood swings and appears depressed.It is reasonable for you to suspect that your friend has begun to take ________.

What name is given to the following reaction? glycerol + 3 fatty acids → triglyceride + 3 water molecules

By definition,what type of fatty acid has double bonds?

If one strand of a DNA double helix has the sequence AGTACTG,what will be the sequence of the other strand?

Complete the equation: monosaccharide + monosaccharide → ________ + water

The amount of carbohydrates in a food product is usually separated into two groups: 1)sugars,which refers only to mono- and disaccharides,and 2)fiber.Out of the 22 grams of total carbohydrates,there are 12 grams of sugars and 2 grams of fiber in the chocolate mint cookies.All of the following statements EXCEPT for one are true.Choose the exception.

Oleic acid is a fatty acid that occurs naturally in many animal and vegetable fats and oils.What can you tell about oleic acid just by looking at its structure?

________ is a hydroxyl group.

The ability to tolerate lactose throughout life most likely arose in ________.

The figure below shows ________.

What name is given to the following reaction? galactose + glucose → lactose + water
