Answer 15

cellulose and pectin

Question 16

define monosaccharides

Answer 16

monosaccharides are the simplest unit of carbohydrates. Fructose, galactose and glucose are the most common monosaccharides fund in food.

Question 17

define fructose

Answer 17

Fructose, or frit sugar is the sweetest natural sugar. It can be found in honey fruits and vegetables.

Question 18

define galactose

Answer 18

Galactose does not exists alone in food. it bons with glucose to form lactose , a disaccharides found in milk.

Question 19

define glucose

Answer 19

Glucose is the most important monosaccharides as it serves as a main source of energy. It is found in fruits certain vegetables and honey

Question 20

define disaccharides

Answer 20

disaccharides consist of two units of monosaccharides bonded together. The most common disaccharides in food include lactose (milk sugars), and maltose (malt sugar) and sucrose (can or table sugar)

Question 21

define lactose

Answer 21

A molecule of lactose consists of a glucose molecule bonded to galactose molecule. Lactose is found naturally in dairy milk.

Question 22

define maltose

Answer 22

A molecule of maltose consists of two glucose molecule bonded together. Maltose is found naturally in sugar molecules (syrups), germinating barely and sweet potato

Question 23

define sucrose

Answer 23

A molecule of sucrose consists of a glucose molecule bonded to a fructose molecule. Sucrose is found naturally in sugar cane, honey fruit and certain vegetables.

Question 24

Answer 24

they tend to be more sweet

Question 25

what are the two neutral food groups that have both complex and simple carbohydrates.

Answer 25

fruits and vegetables

Answer 27

vegetables: tomato and yam Fruits: apple and orange Pulses: dhal and kidney beans Processed food: pasta and yellow noodles cereals: Oats and brown rice.

Question 28

Define complex carbohydrates

Answer 28

Complex carbohydrates consists of mainly polysaccharides. Starch and dietary fibre are examples of polysaccharides in food.

Question 29

define polysaccharides

Answer 29

Polysaccharides are large carbohydrate molecules made up of more than 10 units of monosaccharides bonded together. Starch can be digested but dietary fibre cannot be digested.

Question 30

Define starch

Answer 30

Starch consists of hundreds of glucose molecules joined together into a chain-like structure. It is abundant in cereals and tubers.

Question 31

Define Cellulose

Answer 31

Cellulose is an insoluble component of cell walls that provides support to plants. Fruits, vegetables, wholegrains and beans are good sources of cellulose.

Question 32

Define Pectin

Answer 32

Pectin is a soluble component found in the cell walls of certain plants. Apple, apricot, citrus fruit and plums are good sources of pectin.

Question 33

What are the two functions of carbohydrates in the body

Answer 33

- source of energy -aids digestion

Question 34

elaboration for source of energy (function)

Answer 34

Carbohydrates are one of the main sources of energy that fuels a persons daily activities. Due to it giving 4 Kcal enrgy for eah gram of carbohydrate digested
