Carbon-Carbon is the chemical element with
symbol C and atomic number 6. As a member of
group 14 on the periodic table, it is a non-metal
 Hydrogen-Hydrogen is the chemical element with
atomic number 1. It is represented by the
symbol H. Hydrogen is the lightest and most
abundant chemical element
 Nitrogen-Nitrogen is a chemical element that has
the symbol N, atomic number of 7 .Elemental
nitrogen is a colorless, odorless, tasteless and
mostly gas at regular conditions.

Oxygen-is the element with atomic number 8 and
represented by the symbol O. is a highly reactive
nonmetallic period 2 element that r forms compounds
with almost all other elements
Phosphorus-is the chemical element that has the
symbol P and atomic number 15. A nonmetal of the
nitrogen group, phosphorus is commonly found in
rocks. Elemental phosphorus exists in two major
forms - white phosphorus and red phosphorus.
Sulfur-is the chemical element that has the atomic
number 16. It is denoted with the symbol S. It is an
abundant, non-metal. Sulfur, in its native form, is a
bright yellow crystalline solid. In nature, it can be
found as the pure element and as minerals. It is an
essential element for life and is found in two amino
acids: cysteine and methionine.
A
chemical bond is an attraction between
atoms or molecules and allows the formation
of chemical compounds, which contain two
or more atoms.
 A covalent bond is a form of chemical
bonding that is characterized by the sharing
of pairs of electrons between atoms, and
other covalent bonds.
 An ionic bond is a bond formed by the
attraction between two oppositely charged
ions.
 Carbohydrates
are organic compounds that
consist only of carbon, hydrogen and oxygen.
 The physical properties of carbohydrates
include a chain like shape as shown in this
picture ->
 Lipids
are hydrophobic. Which means that
they are repulsive to water.
 Lipids also have Lipophilicity which means
that they are fat loving.

Enzymes are mainly proteins, that increase the rates of
chemical reactions.
Proteins-are organic compounds made of amino acids
and are arranged in a linear chain.
Amino Acids-Organic compounds made of carbon,
hydrogen, oxygen, nitro gen, and sulfur bonded in
characteristic formations. Strings of amino acids make
up proteins.
Catalysis-The act or process of cat alyzing, or speeding
up the rate of reaction between substances.
 In
water, each hydrogen nucleus is bound to
the central oxygen atom by a pair of
electrons that are shared between them.
 Water is one of the few known substances
whose solid form is less dense than the
liquid. Another interesting property of water
is its high boiling point.
