human milk vs cow milk biochemical structure

[Guest guest]

Before I began I want to say that this will be long so

if there are any replies please delete it so we don't

have to read it in the digest everytime it comes up!

Second, I am pro- breastfeeding having successfully

breast fed twelve children and have been a speaker at

several La Leche groups around the world.

I did a research paper about 9 years ago while in

chiropractic college. I wanted to show how the

standard use of egg for the perfect protein was wrong

and that we should be using breast milk as the perfect

protein model. To make a long paper short, I will tell

you about the biochemical structures of milk.

There are two main proteins in milk. Lactoalbumim and

casein. In cow's milk, it is 80% Casien and 20%

lactoalbumin. In human milk it is the exact opposite

plus the lactoalbumin is l-lacto albumin instead of

D-lactoalbumin which simply means that there is a

molecule on the end of the chain turned left instead

of right.iIt makes a difference to the type of enzyme

that needs to digest that protein whether it is left

or right. In " CLinical Nutrition " the author( I can't

find the author's name sorry) states the all csein

proteins are similiar in all mamalllian milk. I look

up the biochemical structure of casein and found out

that they are not similiar. Casein is a protein and

all proteins are made up of amino acids. THe amino

acids are put in different orders byu the DNA in order

to make different protein structures. THe following is

a list of the different proteins by weight in mg. in

human milk and cow's milk. I will leave out egg here

but it is interesting to see how different egg is from

milk.

Whole cow's milk.

Try thr iso leu lys met cys phe try val arg his wt

Human milk

5 14 17 29 21 6 6 14 16 19 13 7 31g.

So if the weight of the amino acids are different then

there is no way the configuration of the protein can

be the same.What this means is that it takes a

different enyzme to digest the two different milks.

The assay of amino acids in mother's milk is meant to

help a child develop at a much slower rate that a cow.

Every animal has it's won blueprint of amino acid

assays just right for that animal.

One of the reason' why a achild with autism cannot

digest cow's milk is the immune response happening in

the gut. IT destroys the villa of the small intestine.

THis does not happen with mother's milk because it has

live bacteria and enzymes that protect the gut and

digest milk.Human bodies also have enzymes meant to

digest human milk. Cow's milk has a different

configuration and requires a different enzyme to chop

the amino acid chains at the right place.

Pasteurization heats milk to 118 deg. That is the heat

needed to reconfigure the enzyme needed to digest

milk. The test to see if the milk is pasteurized is to

see if that enzyme is gone. Yes. It also kills the

pacteria. However, that doesn't necessarily mean that

a chld with true milk allergies can digest raw cow's

milk. THe reason for that is the lack in the child of

the proper enzyme to help digest milk and also the

immune response to a foreign protein. I do not know if

Cow'w milk has the same antibodies as human milk to

help decrease the immune response.

If a child is reacting to mother's milk then should

find out the offending foods in her diet that the

child is reacting to and remove them. Then she should

clean her colon and liver and use digestive enzymes to

help digest her own food. THen she should put back in

slowly the offending foods to see if the child still

react. Hope this helps with your decision on whether

to breast feed or not.
