Carbohydrates Flashcards
Major food source and supply of the body but not the only source of energy
Carbohydrates
Carbohydrates contains
C,H,O
Carbon
Hydrogen
Oxygen
CHO are _ & _ derivatives of _
aldehydes / ketone derivatives of polyhydroxy-alcohol
Monosaccharides are characterized by:
- Functional Group
(Aldehyde & Ketone) - Number of Carbon Atoms
(Triose, Tetrose, Pentose, Hexose)
ALDEHYDE = Aldose = FG found in _
last part
KETONE = Ketose = FG in _
between 2 C groups
Examples of Monosaccharides:
Glucose
Galactose
Fructose
Ribose
Deoxyribose
Monosaccharide found in seminal fluid
fructose
has 3-6 carbon atoms only
MONOSACCHARIDES
(one saccharide unit only; simplest CHO)
Disaccharides (2 monosaccharide units) joined together by a _
glycosidic linkage
glycosidic bond
ALPHA – oriented _
BETA – oriented _
alpha: down
