Protein And Carbs Flashcards
What is the definition for elemental composition
Elements are individual chemicals. The composition of something is the element that it is made up of. For example protein is made up of the elements carbon (C), hydrogen (H), oxygen (O), and nitrogen (N)
What is a source?
This is a food or something else that provides nutrients to the body. For example, milk is a source of calcium and sunlight is a source of vitamin D
What is an example of a protein source?
Meat,fish,eggs,soya beans,meat alternatives
What are examples of LBV protein foods?
Peas,beans,lentils,nuts,cereals
What are the sources of carbohydrates?
Sugar:table sugar,sweets,jam
Starch:bread,pasta,flour
Dietary fibre:whole cereals,whole meal bread,fruit and veg
What are the classification of carbohydrates?
Carbohydrates come from. 3 different groups:sugar,starch,dietary fibre
What are the classification of protein?
High biological value (HBV) proteins: these are proteins that contain all or most of the essential amino acids needed by body. Most HBV proteins are found in animal sources e.g. meat
Low biological value (LBV) proteins: these are proteins that do not contain many essential amino acids and usually come from plant sources, e.g. cereal
What are functions of proteins?
Protein is needed for the growth and repair of all body cells (skin, bod, tissues onl
• It is necessary for the production of important substances in the body, e.g. hormones enzymes and antibodies (which fight disease).
• It produces heat and energy.
A person needs 1 g of protein per 1 kg of body weight, e.g. a person weighing 70 kg needs 70g of protein
Functions of carbohydrates?
Carbohydrates supply most of the body’s heat and energy.
• Excess carbohydrates are stored as fat (adipose tissue), which insulates the body.
• Dietary fibre is vital for the movement of waste through the intestines, prevents constipation and helps prevent diseases e.g. bowel cancer
What are protein deficiency symptoms?
Slow healing of wounds,poor general health, poor or stunned growth with muscle wasting
What is the definition of classification?
This is a way of grouping similar things together. For example, proteins are classified as high biological value proteins or low biological value proteins
What is the definition of function?
These are the jobs a nutrient carries out the body. For example carbohydrates provide the body with heat and energy
What is the definition of deficiency disease?
These are diseases that occur when the body is lacking a particular nutrient over a period of time. For example, scurvy is a disease resulting from a lack of vitamin C
