hydrolize by enzyme lactase present in the intestine
Disaccharides
Composed of 3 to 10 monosaccharides some up to 20
Oligosaccharides
In the body they are called glycans (glycoprotein and glycolipids)
Oligosaccharides
What are Oligosaccharides called in the body?
Glycans (glycoprotein and glycolipids)
process of binding oligosaccharide to proteins or lipids
Glycosylation
Oligosaccharides that participate in immune responsee
cell recognition- cell receptors
auto antigens (RBC antigen)
The building block of A and B antigen in RBC
H-antigen
Consist of many units of monosaccharides linked together by glycosidic bonds
Polysaccharides
Serves as storage of energy in human and plants
Polysaccharides
Integral part of the cell and tissue structure
Polysaccharides
Exogenous Polysaccharides
Starch
Cellulose
Insulin
Chitin
storage form in plants (amylopectin annd amylose)
Starch
forms the cell wall of plants. also known as dietary fiber
Cellulose
Cellulose is also known as?
dietary fiber
also known as fructans (dietary fibers) found in plants. Used for Glomerular filtration rate estimation
Insulin
forms the cell wall of fungi and exoskeleton of arthropods
Chitin
Endogenous Polysaccharides
Glycogen
Hyaluronic acid
Heparin
storage form in human (liver)
Glycogen
lubricants of the joints
Hyaluronic acid
natural anticoagulant in the blood
Heparin
Major source of energy(glucose) in the body
Polysaccharide
Found as part of the cell membrane of the cell the glycoprotein and glycolipids
Polysaccharides
Forms the building block (oligosaccharides) of ABO antigen in the surface of RBCs
Polysaccharides
One of the major component of nucleotides (pentose)
Polysaccharides
starch and glycogen (polysaccharides) are broken down into Disaccharide in the mouth through?
salivary amylase
Limit dextrin and maltose (disaccharide)
In the small intestine hydolysis occur by the action of ______ to breakdown into monosaccharide
Pancreatic amylase, maltase, sucrase and lactase
From the duodenum and ileum monosaccharide is absorbed into the blood circulation for further metabolism
Glucose
Galactose
Fructose
Depending on the need of the body glucose can be?
Used as energy
stored in the form of glycogen
stored in the form of triglycerides
converted in protein, amino acids and keto acids
used for energy production through production of ATP, CO2 and H2O
GGlucose
3 process of energy production through ATP (glucose)
Glycolysis
TCA cycle (Krebs cycle)
Electron Transport Chain
The process of storing in the form of glycogen in the liver and peripheral tissues like skeletal muscle.
Glycogenesis
Process of storing as triglyceerides in adipose tissues
Lipogenesis
Process that occurs in the skeletal muscle converted into keto-acids, amino-acids and protein
Cori cycle (glucose-alanine cycle)
Processes of glucose metabolismm
Glycogenesis
Glycogenolysis
Gluconeogenesis
Glycolysis
Lipogenesis
Lipolysis
Conversion of excess glucose to glycogen to be stored in the live and peripheral tissues
Glycogenesis
This process occur when cell is already met the energy requirement, glucose is stored as glycogen
Glycogenesis
Process of glucose metabolism that reduces blood sugar level
Glycogenesis
Stored glycogen in the liver is broken down into glucose for energy production
Glycogenolysis
This process occur during fasting state
Glycogenolysis
Process that is stimulated by glucagon and epinephrine
Glycogenolysis
This process is inhibited by insulin and increases blood sugar
Glycogenolysis
Formmation of Glucose-6-phosphate from non-carbohydrate source such as lactate, amino acids (keto acids) and glycerol
Gluconeogenesis
This process occurs in the liver, kidney, skeletal muscle, intestine, and brain
Gluconeogenesis
This process occur during prolong starvation and increases the blood sugar level
Gluconeogenesis
process where glucose is metabolized into pyruvate and lactate releasing energy (ATP) and this process reduces blood sugar level
Glycolysis
