Proteins
A protein is a complex, high molecular weight organic compound that consists of amino acids joined by peptide bonds. Protein is essential to the structure and function of all living cells and viruses. Many proteins are enzymes or subunits of enzymes. Other proteins play structural or mechanical roles, such as those that form the struts and joints of the "cytoskeleton." Proteins are also nutrient sources for organisms that do not produce their own energy from sunlight. Proteins differ from carbohydrates chiefly in that they contain much nitrogen and a little bit of sulfur, besides carbon, oxygen and hydrogen. Proteins are a primary constituent of living things.
In carnivores protein is one of the largest component of the diet. The metabolism of proteins by the body releases ammonia, an extremely toxic substance. It is then converted in the liver into urea, a much less toxic chemical, which is excreted in urine. Some animals convert it into uric acid instead.
Protein nutrition in humans
In terms of human nutritional needs, proteins come in two forms: complete proteins contain all eight of the amino acids that humans cannot produce themselves, while incomplete proteins lack or contain only a very small proportion of one or more. Humans' bodies can make use of all the amino acids they extract from food for synthesizing new proteins, but the inessential ones themselves need not be supplied by the diet, because our cells can make them ourselves. When protein is listed on a nutrition label it only refers to the amount of complete proteins in the food, though the food may be very strong in a subset of the essential amino acids. Animal-derived foods contain all of those amino acids, while plants are typically stronger in some acids than others. Complete proteins can be made in an all vegan diet by eating a sufficient variety of foods and by getting enough calories. It was once thought that in order to get the complete proteins vegans needed to do protein combining by getting all amino acids in the same meal (the most common example is eating beans with rice) but nutritionists now know that the benefits of protein combining can be achieved over the longer period of the day. Ovo-lacto vegetarians usually do not have this problem, since egg's white and cow's milk contain all essential amino acids. Peanuts, soy milk, nuts, seeds, green peas, Legumes, the alga spirulina and some grains are some of the richest sources of plant protein.
All eight essential amino acids must be part of one diet in order to survive and are needed in a fixed ratio. A shortage on any one of these amino acids will constrain the body's ability to make the proteins it needs to function.
Different foods contain different ratios of the essential amino acids. By mixing foods that are rich in some amino acids with foods that are rich in others, one can acquire all the needed amino acids in sufficient quantities. Omnivores typically eat a sufficient variety of foods that this is not an issue, however, vegetarians and especially vegans should be careful to eat appropriate combinations of foods (e.g. nuts and green vegetables) so as to get all the essential amino acids in sufficient quantities that the body may produce all the proteins that it needs.
Protein deficiency can lead to symptoms such as fatigue, insulin resistance, hair loss, loss of hair pigment (hair that should be black becomes reddish), loss of muscle mass (proteins repair muscle tissue), low body temperature, and hormonal irregularities. Severe protein deficiency is fatal.
Excess protein can cause problems as well, such as causing the immune system to overreact, liver dysfunction from increased toxic residues, possibly bone loss due to increased acidity in the blood, and foundering (foot problems) in horses.
Proteins can often figure in allergies and allergic reactions to certain foods. This is because the structure of each form of protein is slightly different, and some may trigger a response from the immune system while others are perfectly safe. Many people are allergic to casein, the protein in milk; gluten, the protein in wheat and other grains; the particular proteins found in peanuts; or those in shellfish or other seafoods. It is extremely unusual for the same person to adversely react to more than two different types of proteins.

Thank you!

While your body has to break down various animal proteins, whey protein is quickly absorbed into the body.
Thank you!

I was wondering the same thing.

There is a certain type of protien wimmins should take regularly. I have plenty in stock.

Absolutely! I'll get your order right over to ya!

I am so very blessed
So, is there a benefit for the whey protein being absored quickly into the body? Does it exit your body just as quickly? And is whey protein better for you than animal protein? If you body has to break down the animal protein, is your body burning more calories to do it?
Probably stupid questions, but I'm asking anyway.....

You got my price yet?Does this have anything to do with that high-protein hand lotion you are always boasting about...

Working on it... geez, you know how hard it is to find and then get a quote from people willing to service you... patience, dude! Patience!You got my price yet?

All those questions above, and "are the protein shakes to help your muscles, or does it provide good energy also?". TIA
I appreciate everyone's information.

Since whey is absorbed faster, it makes a great choice for a meal as soon as you wake up and right after you work out. (Both are times when you're body is starved of nutrients and it offers a quick and effective fix) It's absorbed in the gut faster than animal protein... does it exit as quickly... not sure.
Overall, animal protein is better, especially if you're trying to lean out since it requires your body to work harder to break down animal protein (bruning a few more calories) over whey (plus animal protein takes longer to digest so you feel a bit fuller over a longer period of time), BUT whey is effective post-workout and as soon as you wake up.
