What are the senses of 'spike protein' in the context of sars-cov-2? Please give me an idea of how many 'spike proteins' in each sense there would be per spike, and per virus, to help me get an idea of what exactly is being referred to in each sense of the phrase.
Here are some actual examples:
https://childrenshealthdefense.org/defender/moderna-pfizer-vaccines-blood-clots-inflammation-brain-heart/ The injected spike protein was also found in the lung, spleen, kidney and liver of the mice. [The protein here is clearly more than one molecule.]
https://www.news-medical.net/health/What-are-Spike-Proteins.aspx The viral envelope of coronaviruses is typically made up of three proteins that include the membrane protein (M), the envelope protein (E), and the spike protein (S). [The protein here is clearly more than one molecule.]
https://www.sciencenewsforstudents.org/article/explainer-what-is-a-spike-protein Members of the coronavirus family have sharp bumps that protrude from the surface of their outer envelopes. Those bumps are known as spike proteins.[Sounds like individual molecules are being referred to this time. By the way, "sharp" is flat wrong, no pun intended, since the bumps are not pointed and hence "spike" is a bit of a misnomer. "Stud" or "knob" would seem to make much more sense and indeed they are often referred to as "studs".]
https://globalbiodefense.com/2020/12/22/what-is-the-spike-protein-and-why-are-mutations-on-it-important/ The spike protein is composed of a linear chain of 1,273 amino acids, neatly folded into a structure, which is studded with up to 23 sugar molecules. Spike proteins like to stick together and three separate spike molecules bind to each other to form a functional "trimeric" unit.['up to'? Wouldn't it be a different molecule if it had a different number of 'studs'? The spike molecule is one and the spike molecule is three? Doesn't the spike molecule have a unique name? How about I coin one: 'the thousand two hundred seventy-three plus sugars molecule'? But it does sound like individual molecules are being referred to.]
https://en.wikipedia.org/wiki/Peplomer "Peplomer (sic)[Gr. peplos = robe, (woman’s) dress + Gr. meros = part] (also called a spike) is one of the knoblike structures (spikes), generally composed of glycoproteins (spike protein (sic)), projecting from the lipid bilayer of the surface envelope of an enveloped virus." but on the side of the same part of the page is the image of a single peplomer (correct me if I'm wrong) https://upload.wikimedia.org/wikipedia/commons/thumb/0/02/Novel_Coronavirus_SARS-CoV-2_Spike_Protein_%2849583626473%29.jpg/330px-Novel_Coronavirus_SARS-CoV-2_Spike_Protein_%2849583626473%29.jpg which is captioned: "3D print of the peplomers (sic) of SARS-CoV-2". [glycoproteins are spike protein?; a single peplomer is peplomers? Also, I see six colors in that peplomer. How does that fit with it being a 'trimer']
