Biomolecules

• Amino acids are the building blocks of which group of biomolecules?

  Proteins
• composed of the same chemical elements, but in different proportions

  carbohydrates and lipids
• Both carbohydrates and lipids serve as sources of energy but these compound contain different capacities for energy storage.

  True
• Polymers of amino acid. Proteins
• organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.

  Nucleotide
• both proteins and nucleic acids contain nitrogen in addition to carbon, hydrogen, and oxygen in their structures

  true
• It is a biological catalyst.

  Enzymes
• It contains the genetic instruction used in the development and functioning of all living organisms.

  deoxyribonucleic acud
• Most abundant and widespread organic substances in nature

  Carbohydrates
• Major source of energy for the body

  Carbohydrates
• From the prefix "mono" which means one, the monosaccharide

  is the simplest sugar and the basic sub unit of a carbohydrate. 
• These compounds are white solids at room temperature. 

  monosaccharides
• they have polar, hydroxyl (-OH) groups in their molecular structures are very soluble in water. 

  monosaccharides
• Examples of monosaccharides include glucose also called dextrose, fructose and galactose. The most common monosaccharides are glucose and fructose.
• What structure is this?

  Glucose

  
• What structure is this?

  Fructose

  
• What structure is this?

  Galactose

  
• Compounds with the same molecular formulas are called?

  isomers
• sugar is disaccharide also called as sucrose(C12H22O11).
• Condensation reaction is a reaction in which two molecules or parts of the same molecule combine. 
• When two glucose molecules are combined, maltose is formed and water is lost during the process. 
• A hydrolysis reaction occurs when the bond between monosaccharides is broken with the addition of a water molecule.
• what structure is this?

  Sucrose

  
• what happens when two monosaccharides join together?

  Glycosidic bond
• Lactose is made up of sugar called galactose and glucose.
• People who cannot digest milk products are called "lactose intolerant" because they do not produce the enzyme (lactase) necessary to break the bond between glucose and galactose.
• What structure is this?

  Maltose

  
• A starch molecule is a polysaccharide assembled from the simple sugar glucose.
• Starch is made up of two polysaccharides

  amylose and amylopectin
• Coiled or helical structure

  Amylose
• Branded polysaccharides

  Amylopectin
• Steroids are another class of lipids which molecules are composed of fused rings of atoms.
