Nutrition is crucial for maintaining overall health and well-being. It plays several key roles, including:
1. Carbohydrates: These are the body's primary source of energy. They can be classified into simple carbohydrates (sugars) and complex carbohydrates (starches).
2. Proteins: Proteins are essential for growth, repair, and maintenance of body tissues. They are made up of amino acids, some of which are essential and must be obtained from food.
3. Fats: Fats are a concentrated source of energy and are important for the absorption of fat-soluble vitamins (A, D, E, K). They can be classified into saturated, unsaturated, and trans fats.
4. Vitamins: These are organic compounds essential for various biochemical functions. They are divided into water-soluble (like vitamin C and B vitamins) and fat-soluble vitamins.
5. Minerals: Minerals are inorganic elements that play critical roles in processes such as bone formation, nerve function, and muscle contraction. Important minerals include calcium, iron, and potassium.
Carbohydrates: Mainly found in bread, rice, pasta, fruits, and vegetables.
Proteins: Found in meat, fish, eggs, dairy products, legumes, and nuts.
Fats: Sources include oils, butter, avocados, nuts, and fatty fish.
Vitamins: Fruits, vegetables, whole grains, dairy products, and meats provide various vitamins.
Minerals: Dairy products, meat, whole grains, fruits, and vegetables are good sources of vital minerals.
A balanced diet contains the right proportions of different nutrients to meet the body's needs. It involves:
A balanced diet helps maintain optimal health and prevents nutritional deficiencies.
Proper nutrition is closely linked to health. Good nutrition helps prevent various diseases, including obesity, diabetes, heart disease, and some types of cancer. It also plays a role in mental health, enhancing mood and cognitive function. On the other hand, poor nutrition can lead to malnutrition, impacting physical and mental well-being.
In summary, nutrition is vital for sustaining life, and understanding its components is essential for making informed dietary choices. Key aspects include:
By prioritizing good nutrition, individuals can lead healthier and more fulfilling lives.
chapter 5 enzymes
PH- 0 enzyme velocity = 0
bell shapre = Ph
Temperature = deformed bell
Extreme Ph- enzyme velocity - 0
ph = 7 =optimal Ph
Ph up = enzyme up to 7
after 7 ph up = enzyme down
bloodPh = 7.4 plus or minue 0.4
intracelluar = 7.2
Stomach = 1 or 2
pH = -log(hydrogen concentration)
pH = inversly propotional to hydrogen
Temperature damage in eznyme = permenent
mild pH damage in enzyme = reversable.( when pH is optimal)
Extreme pH = permenent
Factor control enzyme reaction:
To measure 1 variable, other factor must be constant.(fair experiment) (constant variable, control variable)
frozen enzyme will work again when back at optimal pH
