BIOELEMENTS Flashcards
Elements that constitute more than 99% of the matter found in living things
Bioelements
Elements in biomolecules
Carbon, Oxygen, Nitrogen and Hydrogen
Essential element of any living matter. 0.09% of by mass of carbon
Carbon
Most abundant element in Earth’s crust. 46% by mass 23% by atmosphere
Oxygen
The most abundant element in Earth’s atmosphere. 78% by volume
Nitrogen
Simplest element known, one proton one electron. 10th most abundant element in Earth’s crust
Hydrogen
4 biomolecules
Carbohydrates, proteins, lipid and nucleic acid
Greek “Sakcharon” means
Sugar
Also called saccharides. Diverse group of biomolecules that contain carbon, nitrogen and oxygen
Carbohydrates
Two types of carbohydrates
Simple carbohydrates and complex carbohydrates
Called simple sugar, sugar found in fruits, vegetable and milk
Simple carbohydrates
Also called starches, examples are whole grain bread, cereal, starchy vegetable. Contains fiber that helps in digestive health
Complex carbohydrates
3 classification of carbohydrates
Monosaccharide, disaccharide and polysaccharide
Are simple sugar. Derived for Greek single sugar. It is soluble in water
Monosaccharide
3 common monosaccharide
Galactose, fructose and glucose
Sugar found in milk and dairies
Galactose
Mostly found in vegetables and fruits
Fructose
Six carbon sugar carries in bloodstream. Also called blood sugar or dextrose
Glucose
It consists of two monosaccharide. Table sugar or sucrose
Diasscharides
Obtained from sugar cane and sugar beets
Sucrose
3 common diasscharides
Lactose, sucrose and maltose
Commonly know as milk sugar. Found in milk products
Lactose
Composed of glucose and fructose
Sucrose
Known as malt sugar, made up two glucose unit
Maltose
Are complex carbohydrates made of chains of monosaccharide. May act as food in plants in form of starch
Polysaccharide
Four common polysaccharide
Starch, glycogen, chitin and cellulose.
Is a storage polysaccharide in plants. Glucose polymer made up of amylose and amylopectin
Startch
Molecules chains are linear
Amylose
Molecules are long and branched out
Amylopectin
Stored reservoir of energy in animals
Glycogen
Main component of fungi cell wall and exoskeleton.
Main component of beaks.
Useful in industrial and medical purposes
Chitin
Found in all animal products and it is essential to life because it is found in every cell of the body
Proteins
Prokios
Protein
It is the building blocks of protein
Amino acid
Building blocks are linked together by unique chemical bonds
Peptide bonds
Determined by covalent peptide bond
Primary structure
Determined by hydrogen bonds between backbone of the chain
Secondary structure
Determined by all electrostatic interactions
Tertiary structure
Determined by the subunits and different subunits
Quarternary structure
Proteins are made of hundreds or thousands of small unit called
Amino acid
How many amino acid
Twenty common amino acid
Do not have 2p amino acid and have
Incomplete proteins, complete proteins
Amino acid that cannot be produced by the body
Essential aminod acid
Biological molecules that are insoluble in water, but soluble in nonpolar solvent
Lipds
Waxy greasy and oily, known as fats and oil
Lipds
Two classification into two classes of lipds
Saponifiable, non saponifiable
Hydrolyzed bases such as fats, oil and waxes, fatty acid and alcohol
Saponifiable
Phospholipids and sphingolipids
Complex saponifiable
Cannot be broken down by basic hydrolysis
Non saponifiable
Long chain carboxylic acid
Fatty acid
Known as triglycerides
Fats and oil
Are esters but they are harder and less greasy
Waxes
Are important molecules that provide structure and protection to cells
Phospholipid
A class of an organic compound characterized by a molecular structure of 17 carbon atoms. Are family of lipids. Important in field of biology
Steriods
Most abundant steriod in the human body
Cholesterol
Biomolecules present in all living cell. Blueprint of life
Nucleic acid
Made of nitrogenous base, sugar and phosphate group
Nucleotide
Most well known type of nucleic acid and carries the most genetic information
DNA
