MOLECULAR COMPOSITION
NUCLEIC ACID a type of macromolecule WATER
that contains DNA
- DELIVERS ENERGY
that is most critical and the most - ABUNDANT IN THE BODY
radiosensitive target molecules - CONTRIBUTES TO RADIATION EFFECTS
1. Catabolism: breaking down of COMPOSED OF:
macromolecules into smaller units
1. HYDROGEN
2. Anabolism: production of 2. OXYGEN
macromolecules 3. CARBPN
(HOC)
2 TYPES
C1 RADIOBIOLOGY 3
, 1. GLYRCEROL (1 in each molecule)
2. FATTY ACID (3 in each molecule)
LIPIDS FUNCTION
- present in all tissues of the body
- under the skin: Thermal insulator
- fuel: stores energy
CARBOHYDRATES
COMPOSED OF:
1. HYDROGEN
2. OXYGEN
3. CARBON
(similar to lipids)
ALSO CALLED AS
SACCHARIDES
ENZYMES
- biochemical reaction
ALSO KNOWN AS SUGARS
2 TYPES:
1. MONOSACCHARIDES
2. DISSACHARIDES
CARBOHYDRATES FUNCTION
- provides fuel in the body
by: GLUCOSE
- provide shap and stability
HORMONES NUCLEIC ACIDS
- exercise regulatory control
2 PRINCIPAL COMPONENT
secretes by
ENDOCRINE GLANDS 1. RNA
- transfer RNA (tRNA)
- pituitary - messenger RNA (mRNA)
- adrenal -
- thyroid FUNCTION: PROTEIN SYNTHESIS
