Fiber, also known as roughage, is the part of plant-based foods (grains, fruits, vegetables, nuts, and beans) that the body can’t break down. It passes through the body undigested, keeping your digestive system clean and healthy, easing bowel movements, and flushing cholesterol and harmful carcinogens out of the body.
What is carbohydrates chemical formula?
The chemical formula of a carbohydrate is Cx(H2O)y, which denotes some carbons (C) with some water molecules (H2O) attached—hence the word carbohydrate, which means “hydrated carbon.”
Are all carbohydrates polymers?
All carbohydrates are not polymer. Simple sugars are members of the carbohydrate group that are not considered polymers.
Why does your body need carbohydrates?
Providing energy Carbohydrates are your body’s main fuel source. During digestion, sugars and starches are broken down into simple sugars. They’re then absorbed into your bloodstream, where they’re known as blood sugar (blood glucose). From there, glucose enters your body’s cells with the help of insulin.
What are complex carbohydrates called?
Complex carbohydrates: These are also called starches. Starches include grain products, such as bread, crackers, pasta, and rice. As with simple sugars, some complex carbohydrate foods are better choices than others.
Why are starches called complex carbohydrates?
Complex carbohydrates, also known as polysaccharides, are starches formed by longer saccharide chains, which means they take longer to break down.

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 are amino acids found in the cell?
The 20 amino acids that are found within proteins convey a vast array of chemical versatility. 20 Amino Acids are found in living organisms. Amino acids play central roles both as building blocks of proteins and as intermediates in metabolism.
Where are amino acids found?
The best sources of essential amino acids are animal proteins like meat, eggs and poultry. When you eat protein, it’s broken down into amino acids, which are then used to help your body with various processes such as building muscle and regulating immune function ( 2 ).
