Introduction to Biochemistry Flashcards
Who was the father of modern ‘biochemistry’?
Carl Neuberg (German), 1903
What is biochemistry?
A branch of life science which deals with the study of biochemical reactions and processes occurring in living cells of organisms
What are the branches of biochemistry?
medical biochemistry
clinical biochemistry
Medical Biochemistry:
deals with the chemical basis of the human body
Clinical Biochemistry:
deals with clinical diseases/pathological conditions of the human body
What does clinical biochemistry support?
diagnosis, therapy and research of the medical field
What other life sciences does biochemistry relate to?
oncology , microbiology , immunology , medicine & physiology , biology , pharmacology, genetics, pathology, agriculture
What are the areas biochemistry can be divided into?
Conformational
informational
metabolism
CIM
Conformational:
structure and 3D arrangements of biomolecules
Metabolism:
energy production and utilization
Informational:
language for communication inside and between cells
Bioenergetics
the study of energy flow in cells
Name 2 notable breakthroughs of biochemistry
- discovery of the role of enzymes as catalysts
2. identification of nucleic acids as information molecules
The flow of information from nucleic acids to proteins
DNA , RNA , protein
Name some of the biochemical constituents of the cell
carbohydrates lipids proteins vitamins minerals water
Name some of the biochemical constituents of the cell
carbohydrates lipids proteins vitamins minerals water
What are polymers made up of?
single units called monomers
Each type of macro-molecule is an assemblage of
a different type of monomer
Give the monomer of each marcromolecule: Carbs (poly/disaccharide): Lipids (di/triglycerides) Proteins (polypeptides) Nucleic acids (DNA/RNA)
monosaccharide
glycerol and fatty acids
amino acids
nucleotides
A building block to a macromolecule is an example of
an anabolic reaction
A macromolecule to a building block is an example of
a catabolic reaction
Give the macromolecule for each building block: Simple sugar Amino Acid Nucleotide Fatty Acid
Polysaccharide
Protein (peptide)
RNA or DNA
Lipid
What are 3 ways biochemistry has helped us?
- The elucidation (clarification) of molecular causes of 1000s of diseases; sickle cell, inborn errors of metabolism, etc.
- nutrition & maintaining a balanced diet
- disease diagnosis
Vitamin C deficiency can cause what disease?
Scurvy
What are deficiency symptoms of scurvy?
Skin discoloration & bruising Hemorrhaging Anemia Dental issues Exhaustion/fatigue Swelling of joints (edema)
How does scurvy affect a person’s dental health?
loosened teeth and bleeding/ulcerated gums
What is gout?
a complex form of arthritis that is fairly common
Symptoms of Gout include:
SSRT
- sudden/severe attacks of pain
- swelling
- redness and tenderness in 1 or more joints, usually the big toe
Symptoms of selenium deficiency include:
WIMFH
weakened immune system infertility in men & women muscle weakness fatigue/mental fog hair loss
Clinical features of Glycogen Storage Disease Type 1 are:
SICKFH
- short stature - delayed puberty
- IBS
- chronic renal disease
- kidney and liver enlargement
- fasting hypoglycemia
- hyperlipidemia and hyperuricemia
What do biochemists look at?
the atomic level the structural level the cellular level the role of the cell in the organism -communication: cell to cell or biomolecule to biomolecule metabolic coordination
What is the goal of studying biochemistry?
SOFLOM
to describe the structure, organization, and function of living organisms in molecular terms
In order to understand life on the molecular life you must have:
- chemical structures of the biomolecules
- biological function of the molecules
- understanding of bioenergetics
What are the 6 most important elements of life?
COPSNH
- carbon
- hydrogen
- nitrogen
- oxygen
- sulfur
- phosphorus
Define monomer.
a molecule of any class of compounds, mostly organic, that can react with other molecules to form very large molecules, or polymers
What are the functions of water in the body?
- regulates the body temperature through perspiration
- moistens tissues in the eyes, nose, and mouth
- prevents constipation by moving food through the intestines
- carries nutrients and oxygen to cells
- helps dissolves minerals and nutrients to make them accessible to your body
- lubricates joints
