Why is the protein content of plant matter zero, when all cells have DNA, which codes for proteins?

Question

DNA is in all cells, both plant and animal, and, via RNA and ribosomes, codes for the production of proteins - the proteins have various functions. If this is the case, then why is it that in nutritional analyses of foods, specifically vegetables, there is no mention of proteins?

Answer 1

Plant foods in the US are often labeled as having no protein because of the weird US labeling laws. Just because the label says zero protein It doesn't mean they actually contain no protein.

The thing is that US labeling laws only allows a food to list proteins if it is COMPLETE. In simple terms that means that the food on its own has to contain protein in a form that the human body can use for everything.

In contrast plant proteins are INCOMPLETE. They lack certain essential amino acids so the body can't use them on their own. No matter how much proteins these foods may contain if you tried to live on them you would still die of protein deficiency.

Note that this doesn't mean that plants contain no protein. It also doesn't mean that people can't get all their protein requirements from plants of they want to. All it means is that for a plant food to be able to list protein on the label it has to be made of a mix of plant foods, usually a blend of beans and cereals. That blending makes the protein complete.

This weirdness in US labeling laws isn't just restricted to plant foods. Take a look at the label of gelatin or pork crackling some time: zero protein. And that is despite these being animal products and chock full of protein. But once again the protein in gelatin and pork crackling is incomplete so the law says it can't be listed on the label.

Answer 2

Plants have lots of proteins

"Plant protein foods contribute approximately 65% of the per capita supply of protein on a worldwide basis and approximately 32% in the North American region"

Answer 3

properly I understand the point yet random mutation is amazingly able to manufacturing the outcomes you word. remember genes mutate continually by using type of gene mutliplying and branch all at similar time and maximum of those mutation are impartial and reason no change to the species a minimum of it is measureable, although if it comes into play 1000's of generations later. some mirror DNA two times, some in 1/2, some fuse, etc. the area is that this isn't some ribbon being spun yet three-D geometric molecules so all of us get into the thinking "it truly is only a code" even as in reality that's an situation of stuff interacting bodily. Now might want to there be an intelliegence behind the comprehensive technique of Evolution? particular can we've any evidence of this today? No might want to cosmic rays or gravity itself someway play a position in those scenes? particular yet for my own own concept, my God might want to shift atoms and molecules the following and there to apply Evolution as a device to sculpting existence...because it would want to be a outfitted in version gadget to assist suggested lifeform live to inform the tale in an everchanging international. playstation , for the junk DNA area i replaced into lower than the impact that any gene it truly is circuitously attributed to a actual trait replaced into labelled "junk" basically as a time period like we use "gunk" to intend it truly is the goop that holds all of it in a million piece....yet my opinion in this and 1 / 4 nevertheless received't get you a cup of espresso blairnative> No it does no longer violate the second one regulation, in no way has, in no way will. the second one regulation talks about a *closed* device which each organism and Earth are not from now on..both are open platforms so the regulation does no longer keep on with the following. also if appliying common closed device nothign says the upward push in entropy might want to be even throughtout device and maximum of all organic and organic creatures deplete means to accomplish the artwork mandatory to opposite entropy (back in an open device means streams in to provide the juice mandatory for suggested artwork). those arguments are creationist bullcrap that surely demonstrates those people have 0 expertise of straightforward technology and easy English. Einsteinian> technology has a multitude of evidence on the evolution of the interest and has for truly your time...that declare is faux.

Answer 4

It's like saying an encyclopedia is just paper.

It's not the paper or ink, it's the knowlege captured within the pages that make up an encyclopedia.

The "code" is not protein. Just the "assembly directions."

Answer 5

They are wrong. Plants are full of proteins.
