Do proteins come from animal sources that are incomplete proteins?

proteins that come from animal sources are always complete proteins.  proteins that come from vegetable sources are never complete proteins.

That is why you have to eat a diverse diet. Different foods have different proteins and our bodies get the proteins needed from the food we eat.

True!! If you don't eat proteins then your body won't receive things that your body needs in order to develop! Your body won't  develop and you'll have serious illness that can affect you bad! That's why I encouareg you to eat as much proteins as your body needs. Just like we buyt thing we need in order to survive, our body also needs proteins in order to continue running like a car does!

proteins contain 20 Amino acids connected by dipeptide linkages. \n\neach and every amino acid has unique structure and properties, so when they are connected like beads in a chain, of 20 colours to simplify, arrangement can be made in millions of ways which makes it unique.\n\nso diversity comes from the arrangement of amino acids that is called Sequence which is represented in 20 diff alphabets \n\n   Alanine\n   Arginine\n   Asparagine\n   Aspartic acid\n   Cysteine\n   Glutamic acid\n   Glutamine\n   Glycine\n   Histidine\n   Isoleucine\n   Leucine\n   Lysine\n   Methionine\n   Phenylalanine\n   Proline\n   Serine\n   Threonine\n   Tryptophan\n   Tyrosine\n   Valine\n\nwhile giving this answer I came through similar analogy in the source given below that might give you a feel for the subject.

The Rhesis protein marker was first discovered in Rhesis monkeys on their red cells. That's where the name came from. It wasn't until later that they discovered the same protein cluster was present on some human blood cells.\nThe similarities probably stem back from before primates evolved into man. You will find many similar protiens in monkeys to those in humans, just as you will find the same mechanisms for constructing proteins from DNA in every living cell.\n\nBelieve what you will about Adam & Eve.

there is a dry nutritional meal made with the left-overs from the slaughterhouse ... the dry meal is protein rich and is fed to trout in trout farms. you don't throw it in fresh-cooked ... the drying process gives the meal a longer shelf-life.

The amino acids that go into making proteins are so-called alpha-amino acids. This is because they have an amino group (-NH2) on the carbon atom just next to the carboxyl group (-COOH). The simplest such amino acid is glycine, H2N-CH2-COOH. Another simple one is alanine, CH3-CH(-NH2)-COOH (three carbons, the NH2 group on the second one). There are about 22 amino acids that go into the making of proteins. Some are essential: This means that the body cannot make them, and they are needed in the diet. Others are nonessential: The body can make glycine and alanine from other raw materials.

Amino acids.  All proteins are combinations of only these twenty amino acids, which are known as the building blocks of proteins.  The listed source can give you a list of the twenty amino acids.

Whey protein is one of the highest quality proteins.  Protein quality is measured based on the amino acid composition of the protein in comparison with the amino acid proportions the body needs.  Egg is generally considered to have a quality of 100%, and some lecture notes I was given for my med school biochem class put whey protein at second best at about 93%.

Jello is an incomplete protein.(That means that it does not have all the essential amino acids) It contains several types of protein.The protein is obtained from animal protein.

amino acids, but the whole experiment was biased. why? they assumed that the first chemicals in the "primordial pool" were methane, ammonia, hydrogen and water. there is debate on this now because NASA has determined that the earth's "primordial soup" was not made of that. Water, oxygen and nitrogen seem to be more along the lines of reality. besides, linking amino acids together to form proteins is remarkably easy. if you are smart. by chance it "is about the same as the probability that a tornado sweeping through a junk yard could assemble a 747 from the contents therein" as Fredrick Hoyle has said (smart beyond belief, but weird)

It really depends on the hormone. \n\nMost protein hormones (such as insulin and HGH) are made by recombinant DNA technology. Most of the glucocorticoid (eg cortisone), mineralocorticoid (eg aldosterone) and sex hormones (eg estradiol and progesterone) are partially synthesized starting with certain readily available plant hormones. \n\nIn the past some hormones were indeed taken from animals and human cadavers, but with advances in DNA technology and improved methods of chemical synthesis, this has been almost entirely abandoned.

anti freeze proteins are protiens that are produced in fish, insects etc in extreme cold condition. one of the example of a fish which produces AFP is TELEOST fish.\nwhat these protiens mainly do is that they are capable of lowering the freezing point of a solution in a non-colligative manner by lowering the freezing point to the melting point.\nthe difference between the melting point and the freezing point is known as THERMAL HYSTERESIS.\nthese proteins prevent recrystallisation of ice , which is a thermodynamically a favoured process which involves the growth of large ice crystals at the expence of smaller ice crystals..... this is how these protiens work...

There are an estimated 200-300,000 different gene products.  Most of those are changed in some way by secondary modification, so figure about 500,000 to a million just for the types of protein alone.  In addition, there are thousands of lipid and carbohydrate products, as well as individual amino acids, bases, ions, etc.  Well over a million different kinds of chemicals, if you include large organic macromolecules such as proteins.

lack of protein perhaps....

no, proteins are not produced there.  proteins are produced in the cytosol and transported to the mitochondria by chaperone proteins that recognize the mitochonrial localization signal in the amino acid sequence of the specific proteins.  these proteins are then shuttled throught specific channel protein complexes across the mitochodrial membrane and into the mitochondria.

I'm a vegetarian. Lentils are full of protein.  I've posted a link that is awesome and full of tons of great info.
