Pyridoxal (PL)
caa Pyridoxamine (PM)
STRUCTURE
Pyridoxal phosphate
PYRIDOXINE [B6]
Phosphorate •Intestine
alkaline
Deposohated •In blood
Phosphorate
Deposohated
In live by kinase
In blood Pl PLP Pyridoxine kinase
Alkaline phosphatase
Sensitive to high temperature
Transamination
Deamination
Decarboxylation
Desulfuration
Production of Niacin
Glycogenolysis
Healthy skin
Healthy mucous membrane
Metabolism and formation RBCs
In nervous and immune system
Maintain blood glucose level
Convert blood carbohydrate to glycose
Reaction type Example
Deamination Serine → pyruvate + NH3 Threonine → propionic acid + NH3
Decarboxylation glutamic → ϒ amino butyric acid (GABA)
-amino ẞ-keto adipic → ϒ amino levulonic acid
desulfuration cysteine → pyruvic acid

Vit B7(biotin ) Vit h
Coenzyme r Growth factor
Anti egg white injury factor
Heterocyclic sulfur Consist of imidazole ring + thiophene ring
It is widely distributed in the
foods
Liver, kidney, vegetables and egg yolk are important
source
Biotin also synthesized by
intestinal bacteria
Chocolate

Yeast
Mushrooms
BIOTIN - SOURCES
BIOTIN - FUNCTIONS
Cell growth
Hair & skin & mucous membrane
Co2 fixation
Production of fatty acid
Maintains of blood sugar level
Acetyl coA → methyl coA → in synthesis of fatty acid
Propionyl COA → methyl malonl COA
Acetyl co carboxylase
Propionyl COA carboxylase
BIOTIN DEFICIENCY
1) Hair loss 2) Muscle pains 3) Dermatitis 4) Vomition
