- FADH2 – FLAVINE ADENINE DINUCLEOTIDE
- ATP – ADENOSINE TRIPHOSPHATE [chief]
- ADP – ADENOSINE DIPHOSPHATE
difference of organic compounds from inorganic compounds
presence of carbon atoms
4 organic compounds in the organism’s body
- Carbohydrates
- Proteins
- Lipids
- Nucleic Acids
simplest and the most abundant organic compounds
Carbohydrates
store energy and provide shape to organisms
Carbohydrates
3 classes of CHO
- sugars
- starches
- celluloses
the simplest form of sugar
monosaccharides
building blocks of more complex carbohydrates
monosaccharides
main building block of sugar
glucose
end product of digestion
glucose
fruit sugar
fructose
milk sugar
galactose
2 monosaccharides to disaccharides
dehydration synthesis
disaccharides to 2 monosaccharides
hydrolysis
two simple sugars bonded together
disaccharides
Fructose + Glucose
Sucrose
Galactose + Glucose
Lactose
Glucose + Glucose
Maltose
made of many glucose molecules bonded together in a long chain
polysaccharides
elements found in proteins but not in carbohydrates
- N (Nitrogen)
- S (Sulfur)
- P (Phosphorus)
- Fe (Iron)
large and complex molecules that consists of amino acid units linked together
proteins
building blocks of proteins
about 20 amino acids
results when two amino acids are joined together
dipeptide
results when two dipeptides are joined together
polypeptide
6 functions of proteins
- Movement
- Structure
- Regulation
- Transport
- Nutrition
- Defense
proteins necessary for the contraction of muscles
actin & myosin
the most abundant proteins in the human body that forms bone, tendons, ligaments, and cartilage
collagen
the hard parts of the skeleton of a vertebrate animal
bone
longest bone
femur
from the Latin word ‘tendere’ means to stretch a tough cord or band of dense white fibrous connective tissue that unites a muscle with some other parts
tendons
a tough band of tissue connecting the articular extremities of bones or supporting an organ in place
ligaments
translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos and in some joints, respiratory passages and the external ear
cartilage
process of bone formation
ossification
proteins that control chemical reactions in cells and can speed up some reactions by more than a million folds
enzymes
transport protein used to move Oxygen throughout the body
hemoglobin
stores amino acids for milk use by some newborn animals
casein
first milk that the body produces during pregnancy
colostrum
proteins that help animals fight off the invasion of viruses and bacteria
antibodies
fats and other substances that contain elements like C, H, with less O than in carbohydrates
lipids
group of chemicals that include fats, oil, waxes, phospholipids and steroids
lipids
carbohydrates when energy is stored for a longer period of time
fats
lipids that are solid in room temperature
fats
lipids that are liquid in room temperature
oils
important structural chemicals in cells
phospolipids
last group of lipids thst serves as structural and control function in our body
steroids
components of the membranes that surround the cells
cholesterol
large, complex molecules that contain hereditary or genetic information (DNA)
nucleic acids
building blocks of nucleic acids
polypeptide/nucleotide
the macromolecule that makes up the major portion of the chromosomes
nucleic acids
two kinds of nucleic acids
- DNA (Deoxyribonucleic Acid)
- RNA (Ribonucleic Acid)
found only inside the nucleus of the cell
DNA
carries instruction that control the activities of the cell
DNA
five-carbon sugar (pentose) in DNA
deoxyribose
Nitrogenous Bases in DNA
- cytosine (C)
- guanine (G)
- adenine (A)
- thymine (T)
found both inside and outside (cytoplasm) the nucleus
RNA (Ribonucleic Acid)
sugar in RNA
ribose
Nitrogenous Bases in RNA
- cytosine (C)
- guanine (G)
- adenine (A)
- uracil (U)
3 types of RNA
- Messenger RNA (mRNA)
- Ribosomal RNA (rRNA)
- Transfer RNA (tRNA)
purines nitrogenous bases
adenine (A) & guanine (G)
pyrimidine nitrogenous bases
thymine (T), cytosine (C), &Uracil (U)
a biochemist that shared with the scientific community two crucial insights into the composition of DNA
Erwin Chargaff
start codon
initiator - AUG
stop codon
terminator - UAA UAG UGA
