PROTEINS (POLYPEPTIDES)
NUCLEOTIDES
CELLULOSE:
NUCLEIC ACIDS
POLYSACCHARIDES
LIPIDS
PROTEINS
AMINO ACIDS
NUCLEIC ACIDS
GLYCOGEN (or animal starch):
MONOSACCHARIDES
FATTY ACIDS & GLYCEROL
LIPIDS
NUCLEIC ACIDS
CARBOHYDRATES (POLYSACCHARIDES, COMPLEX SUGARS)
STRUCTURAL fibrous protein that provides elasticity to skin.
Contain the elements CARBON, HYDROGEN,
OXYGEN, NITROGEN and SULPHUR.
Are NOT considered to be polymers, as there
are a variety of structural units.
Nitrogenous bases of DNA are Adenine, Cytosine, Guanine and
Thymine. In RNA Uracil replaces Thymine.
structurally similar to fats but a phosphate
group replaces one of the fatty acid chains,
thus giving this molecule a POLAR and NONPOLAR region. Structurally form two layers to
create the plasma membrane vital to all cells.
PROTEINS
Contain the elements CARBON,
HYDROGEN and OXYGEN.
PHOSPHOLIPIDS:
Primary role is that of storing
of energy.
STARCH (amylose):
Four structural levels: PRIMARY, SECONDARY, TERTIARY and QUATERNARY.
There are 20 amino acids that differ structurally in the R-GROUP,
with only methionine and cysteine containing sulphur.
Two monosaccharides joined together form DISACCHARIDES, such as
sucrose (glucose and fructose) and maltose (glucose and glucose).
Contain the elements CARBON, HYDROGEN, OXYGEN,
NITROGEN and PHOSPHOROUS.
Contain the elements CARBON, HYDROGEN and OXYGEN.
is the hereditary material that can self replicate and be passed on from
parent cell/organism to daughter cell/organism.
All contain FATTY ACIDS that consist of chains of carbon and hydrogen.
As a monomer, primarily role is that of an energy source.
simplest is CHOLESTEROL that consists of a 4 ringed carbon
structure and has a structural role in the plasma membrane. Other
steroids act as HORMONES, eg testosterone and progesterone.
STEROIDS:
contains the information (in genes) for the instructions for making proteins.
a string of glucose monomers. Used by plants for energy storage.
Made up of phosphate group, ribose sugar and nitrogenous base.
Monosaccharides form carbon-ring structures (5C= fructose or 6C = glucose).
