most significant in monosaccharides
glucose
Location of the Carbonyl Group: Co is located at the internal carbon
Ketose (Ketone)
Location of the Carbonyl Group: CO is located at the end of the carbon chains
Aldose (Aldehyde)
Type of Stereoisomerism: polygonal in shape, refers to the position of the -OH in the anomeric C1
Haworth Projection
mirror image, some chemical formula different configuration
Stereoisomerism
Type of Stereoisomerism: Refers to the position of the hydroxyl group AWAY from the aldehyde functional group
Fischer Projection
has glucose, galactose, fructose
simple sugars
cannot be hydrolyzed to a simpler form
Monosaccharides
All monosaccharides formed together or at least two
Disaccharides
Chaining of 3-10 sugar units
Oligosaccharides
Type of Disaccharides: Glucose + Fructose , Common table sugar
SUCROSE
Type of Disaccharides: Glucose + Glucose
Maltose
Type of Disaccharides: Glucose + Galactose, Milk Sugar
LACTOSE
Type of Polysaccharides: Primary CHO in the diet and is found in most plants (glucose molecules)
STARCH
Type of Polysaccharides: The storage form of CHO, Formed from glucose by the liver and muscle
GLYCOGEN
Type of Polysaccharides: Another polysaccharide in plants, Not digested by humans, it does not provide bulk for proper intestinal functioning (25-2500 glucose units)
CELLULOSE
osmotic resistance necessary for cartilage to resist
Aggrecan

source of salivary amylase
salivary glands
mechanical digestion
mouth
Completes the digestion of starch and glycogen
Pancreatic Amylase
source and route of pancreatic amylase
source: pancreas
route: small intestine
digestion of disaccharides
small intestine
Intestinal Absorption: need para makapasok sa energy or ATP, Glucose and Galactose
Active Transport
Intestinal Absorption: no need ng energy or ATP, Fructose
Passive Transport
meaning of genesis?
creation
Catabolism of Glucose to Pyruvate or Lactate with the production of ATP
Embden- Meyeroff (Glycolysis)

Hexose Monosphosphate Shunt
Glucose is converted to glycogen (occurs after heavy meal)
Glycogenesis
Breakdown of Glycogen to form GLUCOSE
regulates glucose levels between meals
Glycogenolysis
Breakdown of Glycogen to form GLUCOSE
Regulates glucose levels between meals
Glycogenolysis
