Revision guides Exam 28 June Today: Become familiar with the nutritional content of protein Understand how proteins are made Be able to know and explain the difference between HBV and LBV proteins.
Protein. Sources, types, alternative proteins (sensory testing) Vegetarians & Vegans Meat Fish Eggs
It is the amino acids in protein which we need for the growth and repair of our bodies
Out of these 20 amino acids we require our body can make 11 of these naturally.
9 amino acids our body cannot make and we get them from the products we eat……...
HBV or LBV??? High Biological Value Protein These contain the 9 amino acids our body CANNOT make. Therefore they contain a high amount of protein. High protein foods are also known as ‘High Risk’ – because bacteria thrive on high protein foods. Low Biological Value Protein These do not contain the 9 amino acids our body CANNOT make. These are lower in protein, and so you must eat a large range of them to ensure you consume the 9 amino acids we cannot make. Nut allergies?
