Lipid Identification and Calorie Energy of Food

Flashcards based on lecture notes covering the identification of lipids, energy yield of food nutrients, basal metabolism, and calorie requirements.

What components are necessary for the lipid identification activity?

Soyabean oil, ethanol and water.

What is the observed outcome when water is added and shaken during the lipid identification methodology?

The oil solution will be of somewhat muddy colour.

Which oils are specified to repeat the lipid identification experiment with?

Mustard, coconut and sesame oil.

How much energy does $1\,\text{gram}$ of carbohydrate yield?

$4\,\text{kilocalorie}$ of energy.

How much energy does $1\,\text{gram}$ of protein yield?

$4\,\text{kilocalorie}$ of energy.

How much energy does $1\,\text{gram}$ of fat yield?

$9\,\text{kilocalorie}$ of energy.

What is the calorie value of vitamins, mineral salts, and water considered to be?

Zero.

Which metabolic activities inside the body are mentioned in the transcript?

Digestion of food, respiration, and blood circulation.

What is basal metabolism?

The energy needed to run the metabolic activities inside the body.

How many calories make $1\,\text{kilocalorie}$?

$1000\,\text{calories}$.

What is the measuring unit of heat obtained from food?

Kilocalorie.

In what two ways is energy used in the human body?

1. Inside the body e.g basal metabolism and 2. Physical activity.

What three main factors determine the demand of calorie or heat energy for a person?

Age, height and weight of the body.

What additional factors cause the amount of daily energy used by a person to vary?

Sex, body-size, occupation and special conditions such as pregnancy.
