PROTEIN AND NUCLEIC ACIDS Flashcards
what is the monomer of protein
amino acids
are made up of amino acids combined
through a dehydration link called a peptide bond.
Proteins
Proteins are made up of amino acids combined
through a dehydration link called a
peptide bond
four elements in protein
Carbon,
Hydrogen,Oxygen, and Nitrogen
5 examples of protein and their functions
- keratin
- fibroin/silk protein
- collagen
- enzymes
- myoglobin
found in hair, skin, and nails.
Keratin
found in silk.
Fibroin / Silk protein
has a smooth and soft texture
Silk
It is one of the strongest natural fibers that have high resistance to deformation.
Fibroin / Silk protein
It is also a good insulating material.
Fibroin / Silk protein
major insoluble fibrous
protein found in connective tissues
such as tendons, ligaments, skin,
cartilage and the cornea of the eye.
Collagen
-comprises as much as 30% of
proteins in animals.
Collagen
how many percent of proteins in animals
30%
what are the 5 connective tissues that has collagen
- tendons
- ligaments
- skin
- cartilage
- cornea of the eye
function to catalyze chemical reactions.
Enzymes
-either speed up a reaction, lower the needed energy for a
reaction to take place, or bind substances to their specific
partners.
Enzymes
3 Examples of enzymes
- lipase
- pepsin
- sucrase
help in digestion of fats
Lipase
help in breaking down proteins into peptides
(smaller units)
Pepsin
also called invertase; help in the digestion of
sugars and starches
Sucrase
are polypeptide that stores
oxygen in muscles. It contains a heme
group which has an iron where the
oxygen is stored.
myoglobin
are also known as polynucleotides
nucleic acids
nucleic acids monomers are —
nucleotides
their essential role in the storage, transfer, and
expression of genetic information.
Nucleic acids
