also causes dry and rough skin.

one can become more susceptible to infectious diseases because damages the lining of the gastrointestinal and respiratory tracts, so they can't act as effective barriers against bacteria.

plugging of hair follicle with keratin, forming white lumps

calciferol
1,25-dihydroxy
vitamin D ( calcitriol)
animal version :
chilecalciferol
plant version :
ergocalciferol
function of
vitamin D

mineralization of bones by :
a) raises blood calcium and phosphorus by increasing absorption from digestive tract.
b) withdrawing calcium from bones
c) stimulating retention by kidneys.
sources of
vitamin D
synthesized in the body with the help of sunlight.
fortified milk, margarine, butter, cereals and chocolates mixes
beef, egg yolks, liver, fatty fish, (salmon, sardines) and their oils.
vitamin D
deficiency
rickets in children
a) Inadequate calcification, resulting in misshapen bones (bowing of legs).
b) enlargement of ends of long bones (knees and wrists).
c) Deformities of ribs (bowed with beads or knobs).
d) Delayed closing of fontanel, resulting in rapid enlargement of head.
e) Lax muscles resulting in protrusion of abdomen.
f) Muscle spasms.
vitamin E
alpha-tocopherol
alpha-tocotrienol

Menaquinone
Menadione
Naphthoquinone
function of vitamin K

deficincy of vitamin K
WATER SOLUBLE
vitamin B
vitamin C
1) antioxidant (stabilization of cell membranes, regulation of oxidation reactions, protection of polyunsaturated fatty acids and vitamin A)
2) reduce platelet aggregation and oxidation of LDL and reduce heart disease.
3)protect oxidative damage to red blood cell membrane.
4) help in iron metabolism
5) maintain nervous tissue and immune function
deficiency symptoms :
a) red blood cell breakage
b) nerve cell damage
necessary for blood clotting and synthesis of proteins found in plasma, bone and kidneys.
bacterial synthesis in the digestive tract
liver
leafy green vegetables, cabbage type vegetables.
milk
more likely to have bruising and bleeding
hemorrhaging (the loss of blood or blood escape from the circulatory system
