Which statement regarding digestion and absorption is true?
So, the correct answer is ‘ Fructose and amino acids are absorbed through intestinal mucosa with the help of carrier ions like Na+’.
Who would benefit most from eating a variety of protein foods so that amino acids that are low in some foods will be supplied by the others?
Who would benefit most from eating a variety of protein foods so that amino acids that are low in some foods will be supplied by the others? A vegan. The variable part of an amino acid is the _____.
Which protein rich food would be a good source of calcium for vegetarians?
Beans, peas, and lentils contain decent amounts of calcium and are great sources of protein and fiber. Soaking, sprouting, or fermenting them can improve nutrient absorption.
Which of the following is the variable part of an amino acid?
The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).
Where does digestion start?
Digestion begins in the mouth. The food is ground up by the teeth and moistened with saliva to make it easy to swallow. Saliva also has a special chemical, called an enzyme, which starts breaking down carbohydrates into sugars.
Where does protein digestion begin?
Protein digestion begins in the stomach, where the acidic environment favors protein denaturation. Denatured proteins are more accessible as substrates for proteolysis than are native proteins. The primary proteolytic enzyme of the stomach is pepsin, a nonspecific protease that, remarkably, is maximally active at pH 2.
What foods contain the 9 essential amino acids?
Meat, poultry, eggs, dairy, and fish are complete sources of protein because they contain all 9 essential amino acids. Soy, such as tofu or soy milk, is a popular plant-based source of protein since it contains all 9 essential amino.
What 3 factors determine the amount of protein a person needs?
Protein RDA Many factors can affect how much protein a person needs, including their activity level, weight, height, and whether they are pregnant. Other variables include the proportion of amino acids available in specific protein foods and the digestibility of individual amino acids.
What should vegetarians eat everyday?
As outlined in the Eatwell Guide:
- Eat a variety of fruit and vegetables every day.
- Base meals on starchy carbohydrates.
- Dairy or dairy alternatives are needed for calcium.
- Eat beans, pulses, eggs and other sources of protein.
- Choose unsaturated oils and spreads.
- Limit foods high in fat, salt and sugar.
How can I increase my calcium naturally?
Good sources of calcium include:
- milk, cheese and other dairy foods.
- green leafy vegetables, such as broccoli, cabbage and okra, but not spinach.
- soya beans.
- plant-based drinks (such as soya drink) with added calcium.
- bread and anything made with fortified flour.
What is the best food for vegetarian?
Foods to Eat
- Fruits: Apples, bananas, berries, oranges, melons, pears, peaches.
- Vegetables: Leafy greens, asparagus, broccoli, tomatoes, carrots.
- Grains: Quinoa, barley, buckwheat, rice, oats.
- Legumes: Lentils, beans, peas, chickpeas.
- Nuts: Almonds, walnuts, cashews, chestnuts.
- Seeds: Flaxseeds, chia and hemp seeds.
What makes each amino acid unique?
The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called “R” groups, interact with the environment.
What can denature proteins?
Proteins are denatured by treatment with alkaline or acid, oxidizing or reducing agents, and certain organic solvents. Interesting among denaturing agents are those that affect the secondary and tertiary structure without affecting the primary structure.
What are the 4 protein structures?
It is convenient to describe protein structure in terms of 4 different aspects of covalent structure and folding patterns. The different levels of protein structure are known as primary, secondary, tertiary, and quaternary structure.
