What is/are "human proteins"?

Question

I keep seeing this in my biology textbook on the section about genetic engineering.

Answer 1

You can eat a chicken sandwich, fish sandwich, peanut butter sandwich, egg sandwich, pork sandwich, or etc. All the proteins from all the meat and plants(wheat and peanut) will be broken down into amino acids on digestion. Then they are put back together to form human proteins. These include your muscles, blood protein, skin, protein matrix of bones, etc.

Answer 2

If referred to in a general sense, a "human protein" is a protein (string of amino acids) which is encoded by a gene in the human genome. Your textbook may refer to engineering other organisms to express human proteins. This is done by inserting a human gene into the other organisms' genome.

Good luck!

lysozyme hydrolyzes bacterial cell walls .
collagen serves as scaffolding for support of tissues and organs, most abundant protein .
pepsin hydrolyzes dietary protein in the stomach .
trypsin hydrolyzes dietary protein in the small intestine .
casein found in milk, supplies amino acids to newborns .
insulin acts as a signal for the fed state .
glucagon acts as a signal for the starved state .
myoglobin stores oxygen in muscle cells .
cytochrome c involved in the mitochondrial electron transport chain .
