Monosaccharide and Polysaccharide

Monosaccharide: Monosaccharides, also called simple sugar, are the simplest form of sugar and the most basic units of carbohydrates.

Polysaccharide: a carbohydrate whose molecules consist of a number of sugar molecules bonded together.

Multiple Choice

Monosaccharides consist of..

• One simple sugar

• Lots of sugars linked together

Glucose and Starch

Glucose: is the most abundant monosaccharide, a simple sugar.

Starch: Is a polysaccharide, and is formed from multiple units of glucose.

Multiple Choice

Starch is a polysaccharide which means it...

• is a single molecule of glucose

• is formed from a bunch of glucose molecules

Protein

Protein: A protein is an organic compound made up of small molecules called amino acids. There are 20 different amino acids commonly found in the proteins of living organisms.

Amino Acids, Polypeptides, and Dipeptides.

Amino acids are organic compounds that combine to form protein.

Polypeptides is a short chain of amino acids that link with each other. 

Dipeptide is a form that has two amino acids joined with single peptide bond

Multiple Choice

How are protein made?

• Individual amino acids join together into polypeptide chains, and form proteins.

• Dipeptides build into large blocks, and then combine into protein chains.

Nucleotide

RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base

Multiple Choice

Nucleotides are...

• Carbohydrate building blocks

• Complex sugar building blocks

• DNA and RNA building blocks
