Protien Flashcards
What are proteins made of?
Proteins are made up of long chains of amino acids held together by chemical bonds.
How do amino acid chains form proteins?
Amino acid chains fold to form proteins with specific structures and functions.
Name three functions of proteins in the body.
Proteins support cell growth and division, repair and maintain tissues, and serve as an energy reserve.
What are some protein-rich foods?
Meat, fish, dairy products, eggs, quinoa, Quorn, and soya products.
Name three foods that contain lower quantities of protein.
Bread, peanut butter, and lentils.
What are symptoms of protein deficiency?
Reduced growth, brittle hair and nails, weakened immune system, poor digestion, and kwashiorkor.
What are possible effects of consuming too much protein?
Digestive issues, dehydration, headaches, kidney and liver damage, and cardiovascular disease.
What is the recommended daily protein intake for an average adult male and female?
55 g for males and 45 g for females.
Why do dietary protein needs vary among individuals?
Needs differ due to factors like age, activity level, and pregnancy or breastfeeding.
What is the difference between essential and non-essential amino acids?
Essential amino acids must be obtained from food, while non-essential amino acids are made by the body.
What are high biological value (HBV) proteins?
HBV proteins contain all essential amino acids and are found in foods like meat, fish, eggs, soya, and quinoa.
What are low biological value (LBV) proteins?
LBV proteins lack one or more essential amino acids and are found in foods like beans, nuts, and pulses.
What is protein complementation?
Combining different LBV protein foods to obtain all essential amino acids, e.g., beans on toast.
What are examples of protein alternatives for vegetarians or vegans?
Soya products, tofu, textured vegetable protein (TVP), and mycoprotein (e.g., Quorn).
How is tofu made, and how can it be used?
Tofu is made by coagulating proteins in soya milk into a solid curd; it can be added to stir-fries and curries to boost protein content.
